    • Fai aderire una ventosa accanto a ciascuno dei due angoli superiori del pannello di vetro.

    • Per far aderire le ventose, per prima cosa posizionale con la maniglia orientabile parallela alla superficie del pannello di vetro (come indicato nella prima e nella seconda immagine).

    • Tenendo delicatamente la ventosa contro il vetro, solleva la maniglia orientabile finché non è parallela all'altra maniglia (come indicato nella terza immagine).

    • Se la ventosa non aderisce, prova a ripulire il pannello di vetro e la ventosa con un solvente delicato.

    • Non usare le ventose per traspostare il vetro del display perché se una di esse si stacca lo schermo potrebbe cadere e rompersi.

    • La scatola originale dell'iMac e' un buon posto dove collocare il pannello di vetro. Altrimenti una superficie piana imbottita, come un asciugamano disposto sul tavolo, può andare bene.

    You can easily lift the glass panel off the magnets with only your fingernails (or something thin like a credit card or a guitar pick). No need to buy suction cups you will only use once.

    Nick Caron -

    Yes, you don't need the specific suction cups to remove the display cover - it's held on by magnets, and if you start at the center by the iSight you can work out to the edges and remove it. I had an iPhone screen suction cup around and it helped with balancing the screen when you pull it out fully, but by no ways is it required.

    jtowner -

    Great guide and pretty straight forward the only thing that took me ages and I didn't manage to undo were the power btn cable (step 28) and the thermal sensor (step 25) Seemed like they were glued on! Very difficult to remove and obviously conscious so I didn't break anything!

    Eddie -

    Thanks!!! Worked excellently.

    I used a plunger (clean first ;-) to get the screen off, and http://exirion.net/ssdfanctrl/ for fan control.

    Then, i did not take out the whole display and left it in the hinges on the bottom side and held it up with two small cardboard boxes. Easy enough to disconnect the hdd then.

    I replaced with an ssd, put that into a ssd enclosure. Had to drill an extra hole in it to fasten the pins that hold it in place.

    Used Carbon Copy Cloner to make an image from the old hdd, with the sad connected via usb. Checked it of it booted via System Preferences > Startup Disk. It worked so the took the imac apart and replaced the disk. Booted, everything was working as always, only faster!

    Frank303 -

    I'm replacing my optical drive too. what exactly needs to be plugged into the SSD? I don't have the kit - as I am not sure one is required if I buy something like this: http://www.amazon.com/gp/product/B0056OB...

    Can you please advise? Can I do it with this piece, or do I need to get the entire bracket kit?

    Allen Borza -

    My display data cable forks, with a smaller section going up near the camera board. Where it forks, it is attached to the aluminum plate that attaches around the cpu board. I haven't seen any images that look similar, and I'm stumped at how to remove this second section of the cable. 2010 i7 build to order

    Awolf -

    Agree with the other comments here. Despite buying suction cups, not sure they were necessary as the screen removed very easily. A sat nav suction cup would do the job fine.

    Stuart Bloomfield -

    I can confirm that it is possible to remove the front glass using fingernails rather than suction cups. It isn’t easy, but if you try you should be able to pry off the glass.

    I did this twice: once at the beginning of the procedure and once again at the end, when I realized that a big pice of lint was trapped under the glass.

    gordonhamachi -

    Don’t use suction cups. totally unnecessary. screen pops off with fingernails.

    Kieran Hobbs -

    The reason for caution about suction cups tends to be making sure you don’t apply uneven pressure on the edges of the glass and crack it in the process of removal. I do agree however that some pretty small suction cups would do fine. These suction cups can be had at your local princess auto (Harbor freight) for a few bucks and are useful elsewhere as well. if you use your fingernails or other items just try and do it evenly :)

    Abirinder Brar -

    good duct tape or gaffer tape wrapped around your hands makes an excellent glass removal 'tool'. Even clear packing tape works a charm.

    Stu Blair -

    A great first step that minimizes that first gust of dust migration when the glass is lifted is to clean the glass, sides *and the back* before lifting the glass, and then lift SLOWLY. Most of that dust is already trapped inside and pulled up as the screen lifts, but with care you can keep it there (or gently vacuum out with a micro vac…).

    John -

    before starting any of this…there is a device that you can use that comes with the IFixit kit to format and either clone or restore your hard drive to the new drive…it will save you a lot of headaches..it is a SSD enclosure that you can plug into your existing computer …

    Tomr -

    Thanks for the instructions. Before doing this the first time, suggest to everyone, read through at least twice. This is the easiest step, as you’ll soon see. As for removing the glass, USE suction cups, either the ones the sell here, or others. DON’T skimp. Also wear gloves when handling the glass. Don’t take chances.

    ECJohansen -

    Duct tape works too!

    • Solleva delicatamente il pannello di vetro in perpendicolare rispetto alla superficie dello schermo LCD affinché sia possibile sgombrare i piedini di montaggio in acciaio inseriti lungo il lato sottostante al bordo superiore del pannello di vetro.

    • Estrai il panello di vetro dal bordo inferiore dell'iMac e riponilo da parte con attenzione.

    • Non utilizzare le ventose per trasportare il pannello di vetro; se una sola perde la presa, il pannello può cadere e rompersi.

    • Dopo aver posizionato il pannello di vetro in una posizione sicura, assicurati di rilasciare le ventose, perché con il tempo la forza che esercitano può rompere il vetro.

    • Durante la reinstallazione, pulisci con attenzione la parte interna del pannello di vetro e la superficie dello schermo LCD, poiché la polvere e le impronte digitali saranno sgradevolmente visibili durante l'uso della macchina.

    you should do this mac up, because, for me, one of the suction cup failed, and the glass fall into the lcd screen. Now there is a big hole in it...

    Lau -

    do you still have this panel?

    Alpha Dimension -

    Reassembly: After powering on and running for a few minutes, found a large whitish patch on the screen. Persists after powerdown.

    Turned out to be condensation, though it didn't look like it - more like fine white powder rubbed in. Humidity is very high this time of the year. Fix: start airconditioner in a room, leave it running a while, take iMac in, prise open the glass again. Condensation vanishes instantly. Keep it out for a ~15 minutes running infinite loops to get iMac nicely heated up and fans running. Snap glass back.

    I used a Swiffer dry cloth to get all the dust off the screen while just blowing with my mouth at a steep angle. I know I didn't get every speck, but the screen looks perfect once assembled and lit again. Removing the glass from the screen is pretty easy if you need to re-clean it.

    Jay Gillibrand -

    I used a microfiber cloth instead, which worked well. The same type as yo use to clean eye glasses, but in a larger form factor.

    Daniel -

    The Swiffer idea worked great! I just brush it over the LCD and glass panel lightly, and all dust particles are gone quickly. The screen after boot up looked beautiful. Thanks!

    dtsai2 -

    I strongly recomment to detach the suction cups while working at the rest of the steps. In my case after half an our i heart a crack noise behind me on the table... The vacuum of one of the suction cups braked the glass! maybe there should be a warning in the Repair guide

    shippe -

    I didn't crack the screen, but it popped out of the shims and then popped back in, as if the glass edge is magnetic or has steel in it to connect to magnets. Be careful with this step — it is pretty nerve-wracking, but doable!

    Alex Reynolds -

    You need a big clean surface free, or at least 2 or more free surfaces because the iMac, the glass and the LCD display are quite bulky. You'll also probably need space for a tablet or a laptop to read this guide while you are working. And don't forget room to work on the optical unit and for the tools you are going to use. I covered a large table with a double layer of bubble wrap. In my opinion it's better to put the glass face down to limit powder sticking on the internal surface.

    Roberto Blandino -

    Thanks good advice! I was wondering exactly about the working space issue!

    matteoslataper -

    I am doing this repair now. After successfully lifting off the glass panel (yay!), dust blew out of the lower open edge. So I sprayed a can of air around edges. But a poof of the “air” condensated on the LCD. Does anyone know if I can clean the LCD same as how the glass is cleaned (damp cloth with equal parts white distilled vinegar/distilled water) and if not then how?

    Amy C -

    Hi Amy,

    To clean the LCD panel, I would suggest using a clean microfiber cloth and rubbing alcohol. Distilled water can be used, but avoid regular water, which contains minerals. Make sure the microfiber cloth is absolutely clean and has no hard particles sticking on the surface, which will scratch your LCD when you wipe it.

    Wet the surface with some alcohol and gently wipe with the microfiber cloth. Wipe in one direction.

    Arthur Shi -

    I find that the LCD is not as fragile as we all think. they are very much like any LCD on a tv or monitor. There is no extra glass on the front of a monitor. Not the 23 HP Pro Displays I have anyway. I know this because I punctured one moving my video wall. so I took it apart to know how its put together. I will say, there are several 'lens’ like sheets and a reflective (silver} sheets that are the same size as the panel. and a 1/8”piece of acrylic, all behind the LCD panel. Take care with them and clean as you would your monitor.

    My suggestion is to stand the iMac up after the panel is secured back into the body of the iMac and clean while its vertical. took me 3 attempts before I realized that while laying flat the surface is large and collects dust with mind blowing speed.

    Stu Blair -

    If the LCD glass is badly cracked and broken you need to be extra careful removing as the sharp shard of broken glass can scratch/harm the underlying screen as they may “fall in or onto” the screen below.

    I found that strategically putting sheets of 8x11 paper(s) under the sharpest, largest broken sections help protect the underlying screen. A vacuum was also helpful removing some of the small glass shards.

    Mark Hilliard -

    Be advised: I did a perfect replacement of the hard drive, temperature sensor to the SSD, LCD screwed in, glass cleaned. I went to put back the final glass, I set the bottom edge in place and as I slowly moved to have the magnets take hold, they pulled the screen out of my gingerly held fingers, and smacked into place……cracking the glass! Ugh! So, on this last step, hold tight as you put the glass back in slowly. It will cost you about 40-50 bucks for a new glass (mine is on it’s way).

    R R MOOS -

    Yikes... that sucks. thanks for sharing this information. I took everyone's advice and removed and placed this back very very carefully.

    iSeeU ChilinHomie -

    Don't trust the suction cups after you remove the screen cover. Used both hands to hold this piece carefully!

    iSeeU ChilinHomie -

    As far as the last point of step 2 goes, I would add to the parts list a can of compressed air to get rid of all the dust on the screen frame and the interior body once the lcd is off). When the magnets clip back in dust will shower down onto the lcd and glass if you do not clean the frame well. It will not matter how much you clean the LCD and inside of the glass panel.

    • Rimuovi le otto viti Torx T10 che fissano l'LCD al case esterno.

    Be careful not to lose these screws when they are unthreaded. Use tweeters to grab them before removing the Torx driver.

    Gavin McMorrow -

    To prevent screws close to the magnets to leave your screwdriver, use a straw to encapsulate your screws. This is especially useful when putting them back. See pictures for details: http://cjoint.com/?CLCpN1nmK4M and http://cjoint.com/?CLCpOy6aF9G

    Marc66 -

    That was a brilliant idea. After trying for ten minutes without luck, the straw technique helped immensely.

    • Posa con cura l'iMac su una superficie piana con il supporto in basso.

    • Le tolleranze molto ridotte potrebbero costringerti a usare un piccolo attrezzo a uncino per sollevare il display dal case esterno. Come si nota nella terza immagine, ne abbiamo ricavato uno da una graffetta appositamente ripiegata.

    • Usa un piccolo attrezzo a uncino per sollevare un lato del bordo superiore del display agganciando la cornice esterna in acciaio del display stesso.

    • Dopo aver sollevato il bordo da una parte, mantienilo sollevato dal case mentre usi uno strumento a uncino per sollevare l'altro lato. Per tenere alzato il primo lato mentre sollevi il secondo, Puoi posizionare una matita o una penna sotto il bordo del display, parallela al lato superiore e sporgente dal lato del computer.

    • Non sollevare troppo il bordo superiore del display rispetto al case esterno, perché le due parti sono collegate da diversi cavi a piattina.

    Be very careful not to hook the Bluetooth antenna cable while you're lifting the display out. It's hiding under the top left corner of the iMac. I managed to snag mine with the paperclip and ended up pulling the antenna cable clean out of the tiny gold connector. Some very precise reconstruction work was required to get the cable seated in the connector again and back up to full signal strength.

    Ben Davies -

    My iMac has a couple of bits of mesh tape at the top. I don'r see these mentioned?

    andy pugh -

    I used an isolated screwdriver, since paper clips were too weak.

    • Usa un paio di pinzette per tirare la piattina della sincronizzazione verticale fuori dalla sua sede sulla scheda di controllo del LED vicino all'angolo superiore sinistro del tuo iMac.

    • Su alcuni iMacs invece della piattina ci sono quattro cavi separati, molto fini e molto fragili. Stai molto attento perché se le pinze scivolano lungo la spina, è facile che un cavo fuoriesca dalla spina stessa.

    I had a friend with me so all I did was disconnect the vertical sync ribbon cable, and I had my friend hold up the LCD for a couple of minutes as I swapped out my HDD with an SSD, thus avoiding steps 6-9 and going straight to step 10.

    Gabe -

    Can I purchase this cable separately?

    mamedovmarat -

    After removing the display, I noticed a high pitched whine coming from the machine, different loudness for different levels of display brightness. Reading up on it, it seems that the problem is with the vertical sync cable (and this is a well-known issue with Apple with new machines, too). So be careful when reinserting this cable!

    Adam Hintz -

    I noticed that the vertical sync cable seems to have been updated since the guide was produced. It now has a more normal plug and socket and 'regular' wires instead of the flat ribbon cable shown here. I used narrow nosed pliers instead of tweezers to unclip it as I was afraid that just pulling on the wires could have broken them.

    Eoin -

    WARNING: Take extreme care when removing these wires as mine were not a ribbon cable but individual tiny wires. I removed them cautiously with tweezers OK but when re-inserting, one of the wires came off. Obviously someone had been in here before.

    Peter Sinclair -

    Hi Peter, did you manage to get a replacement? Let me know please - Thanks Paul

    Paul Randall -

    be sure to keep this cable, because it does not come with a new display!

    Julian -

    I changed the HD yesterday and when I reinstalled the Display I had the same problem then Peter Sinclair. I started to panic first. But then I reinstalled the Pannel without re-insterting the cable at all and nevertheless my iMac works perfectly since 14 hours now. I'm really confused!

    muggooz -

    My vertical sync ribbon cable had two of the four contacts bent back, it may even have been like this originally. I straightened them out as best I could under a magnifying glass, and after reinserting, everything is working OK. Seems this cable is not particularly critical. Also, I used needle nose pliers for this and the other connectors, I can't get enough grip with tweezers.

    Andrew Crabb -

    Tweezers didn't work for me due to the angle and lack of grip (they kept slipping and I was concerned about squeezing any harder). I just used my fingers to grab the connector as close to the connection as possible for both removal and insertion and it worked just fine. I have big hands and meaty fingers, so this method should work fine for anyone.

    David -

    I have a late 2009 27" Mac and did something similar to Gabe, but being alone, after unplugging the vertical sync cable, I used two wooden chopsticks to hold the screen at about 45° and without disconnecting any more cables I could quite easily access the Superdrive to remove and replace with a 240GB SSD with help from a caddy from TheNatural2020, which required a tiny modification.

    All in all it took me about 45 minutes and was much easier than expected. It is working at a negotiated SATA speed of 3 Gbps Some report a speed of only 1.5 Gbps, but from what I had read before purchasing the Crucial M500, going for a 6 Gbps SSD is worse on a late 2009 Mac as it has to default to the basic SATA 1 speed of 1.5 Gbps, while the slower 3 Gbps SATA II drive works at 3 Gbps. The time from the Apple logo till the sign-in screen on startup has gone from 33.5 seconds to 8.5 secs, and my internal hard drive is a 7200rpm

    I am VERY satisfied and it was much easier than expected.

    Adam Griggs -

    Thanks for this suggestion! I didn't have chopsticks, but was able to use some pens instead. The pens are shorter, but still provided sufficient room for my tools to get to the screws holding the HD. I noticed there are two large, thumb size, indentations in the frame under the LCD that the pens fit into nicely. Since I did the repair by myself, this really sped up the process and I was able to complete the HD swap and memory addition in about 25 minutes. (I had planned 2 hours. Happy, happy, happy!)

    barry -

    I also did this step and then went straight to step 10. I installed a SSD so I didn't do step 15 either. You can use this to control the fans: http://exirion.net/ssdfanctrl/

    Overall, great guide! Thank you.

    Sam Im -

    Adam's technique with the chopsticks works great. I didn't even have to disconnect the V-sync cable. Mine wasn't plugged in for some reason. I guess the LCD works without it.

    Ashok -

    This was for me the hardest step when reassembling the iMac.

    I had to open and close the iMac several times as each time some of the cables was not properly connected: The vertical sync, the display data cable connector, even the Bluetooth antenna was off at some point and I had to re-open every time! Finally I left the vertical sync cable disconnected as with each operation it was in very bad condition and impossible to plug in. I'm amazed at how bad designed is this cable and how easy is to break it! It's nice to know that they improved it, poor technicians.

    I'd like to replace it in the future but I really don't know how or if it is available in its more up-to-date version… I didn't feel like dissasembling everything again to see how is it connected.

    carolaclavo -

    The portion of this little cable that plugs into the receptor is stiffer than the rest of the cable, but it is very slippery. For me, it was also very tight. Tweezers and fingers just slipped right off of it. Fortunately, I didn't tear the cable. I ended up using needle-nose pliers wrapped with cellophane to get traction. It was also very difficult to reinsert. By raising the display to the maximum level with all the other cables connected, I was able to push it in with my fingers.

    Also: if you get any smudges on the display, a lens pen works great to remove them. I used a swiffer to pick up dust.

    Michael Morris -

    I opened the case as far as I could without stretching this cable and used my fingers to get it. The end of the ribbon where it connects is stiff, so you can grab it there. There's not connector; the stiff part just slides in and out. Getting it back in is a pain, but if you get the perfect angle it slides back in without much force.

    Jay Gillibrand -

    That's what I ran into with my friends iMac as well. it was just (very carefully slid into place. a piece of celotape held it in as we put the pieces together.

    Wizbang FL -

    Pull the cable AWAY from the connector. Some cables have a plastic connector cap attached to the end. This one does not. The cable just slips out as if pulling a stick of gum out of a package. I used my index finger and thumb, no tweezers needed.

    Cameron Moll -

    I also plugged it out with my fingers, got more feeling in them. Put it in the same way. There is no barb or something on the cable, so this should be quite safe when not using too much force. And I also used chopsticks to keep the display up, just like an engine hood.

    Oliver Hahn -

    This ribbon had me flumoxed for a while. I had expected to have to remove the terminal from the circuit board. All you need to do it gently pull on the ribbon directly and it will come out of the terminal.

    Stuart Bloomfield -

    I followed the above tips and used chop sticks as struts to support the internal screen at an angle, whilst I worked on the hard drive. Allowed me to skip the remaining cable removal steps and go straight to step 10. And I didn’t need an extra set of hands to hold the screen whilst I worked.

    Stuart Bloomfield -

    So far so good. Had trouble with this first ribbon wire and not even sure I got it back in all the way. Computer is working just fine right now with Windows 10. The chopstick idea was absolute genius and saved me so much time!

    Matthew Muratore -

    Does this repair require a Hard Drive of the same brand like some of the later iMacs do?

    lee webb -

    The brand doesn’t matter per se, but it’s helpful to have a disk with the same temperature sensor connector. In some cases, it’s stuck to the disk. In other cases, it’s a long, thin connector with 4 pins. Or, it’s a thick, square-ish connector with two pins. I usually take the old disk to the store and ask “do you have a disk that has a temperature sensor that looks like this?” And….if you can’t find such a disk or you want to stick an SSD in there (they’re getting cheaper by the day!), then make sure you get Macs Fan Control software to help you manage the fans that will possibly run at full blast.

    • Ruota il display sollevandolo dal case esterno quanto basta a disconnettere il cavo della retroilluminazione LED dalla scheda di controllo LED.

    Step 7 MAY be better done prior to Step 6. 7's cord comes tight before there is enough lift room to get to Step 6's plug in my opinion.

    Gavin McMorrow -

    Maybe it's just me but I couldn't see how to unclip this. It felt like it should just be a case of squeezing both sides and then pulling, but it was so stuck I was concerned about damaging it.

    If anyone has a little more detail on this step it'd be useful.

    Chris -

    The connector has a simple locking mechanism, essentially a ridge on the top where the thumb is placed in the picture. If you push down gently there the latch raises and you can pull the cable out.

    Rob Purcell -

    Thank You That was very helpful

    Patrick Zelenka -

    I found step 6 the most difficult of the whole procedure. The way I unclipped the connector was from the front, with my thumbnail. There's a little ridge over which the cable clicks tight. If you use your thumbnail to lift the connector over that ridge, you can then easily remove the cable. (Maybe iFixit should that advise to the guide, since especially step 6 is a bit too concise imho.)

    Daan -

    Agreed with previous comment :You should be very careful after step 5 - it may be necessary to do the step 7 before the step 6 because the connector on the motherboard for the LCD data is very very fragile. I broke it and found that a lot of people broke it as well .

    • Premi insieme i due braccetti laterali della spina del cavo di connessione dati per sbloccarla dalla sua sede sulla scheda logica.

    • Sfila la spina del cavo di connessione dati dalla sua presa sulla scheda logica.

    • Stai molto attento quando scolleghi questo cavo perché sia la spina sia la presa sulla scheda logica sono estremamente fragili. Quando sarà il momento di ricollegarlo, usa la massima delicatezza possibile.

    I just spent 100€ at the Mac shop to learn this: when reattaching the display data cable be sure you get the ends right. Even if the cable fits perfectly the other way round, the computer won't even start.

    Julian -

    NOTE!  The internal video connector on the logic board is quite fragile - proceed with extra care when disconnecting. There are many postings of Mac users who have broken the display connector and are then left with quite a challenging proposition to replace it. Here is the link to one such thread: http://forums.macrumors.com/showthread.p....

    thorjurgen -

    Ditto. It is very fragile. Mine pulled off the motherboard while doing the upgrade (all else went well). Problem occurred because I tried to do the drive swap without removing the display. I had someone hold it up for me. Display is heavy and you can't feel the tug of the cable. Disaster.

    The repair is beyond most computer repair folks. Found these guys http://www.dttservice.com/ and they are great. For $195 they fixed it in 24hours.

    Dave -

    I ran into a big problem with step 7: my display data cable did not have any sort of plug to connect to the logic board. Instead, the cable seemed to be soldered onto the board or simply run under this small copper-colored band. There was no plastic plug to detach/attach.

    I was afraid to pull on the cable and break something, so I simply had a friend hold up the LCD and I replaced the logic board without removing the display. I'm not sure what I would have done if I needed to replace the drive.

    Has anyone else run into this issue where the display data cable doesn't have a plug? And are there alternative ways to detach it safely?

    fronesis -

    @fronesis - on my iMac it wasn't possible to pull out the connector at first. There was a small rectangular metal clip which locked the connector in place - this had to be pulled up first, and then the connector came out extremely easily.

    johnrowell -

    I'm having blackscreen issue and this cable is my main suspect. Here is my post regarding this issue.

    Black screen after SSD install (suspect is monitor cables)

    Mads -

    you will break your computer if you follow this step during the reassemble!

    it’s not possible to reconnect the display with the board because the cable is way to short to maneuver the connector in place and you have almost no sight - you’ll not see what you’re doing! the better approach is disconnect the cable on the display as well (since the connector here is more robust) and insert the connector on the board as a first step without having the display in front of your face..

    • Solleva il display quanto basta per scollegare il cavo del sensore termico dell'LCD dalla sua presa sulla scheda logica.

    • Se la ventola girasse sempre alla massima velocità dopo aver eseguito il lavoro, controlla questa connessione oppure il cavo del sensore termico dell'hard disk. La presa del sensore termico è molto fragile, quindi stai molto attento quando riconnetti il cavo del sensore termico.

    Be very very careful when you pull out this plug as it is extremely fragile and also reattaching the LCD thermal sensor plug and very very gently ensure that the pins are actually going into the connector before you push the plug in. i damaged the top part of the plastic housing which then made it difficult to insert the plug into the connector. I can't believe how easy it was to damage this connector!! If you don't attach the LCD thermal sensor plug correctly the Mac fans will go crazy at full speed. It took a good 15 minutes to get the pins to finally go into the plug and they can bend easily.

    j74656 -

    This was too tight to get with my hands. I used needle nose pliers to grab the plastic connector and it popped right out. I need pliers to get it to snap back in too. The wire itself if very thin so be sure to only grab the connector.

    Jay Gillibrand -

    The connection of this cable is moot (and to the main drive too) if you purchase HDD Fan Control Monitor software that uses the SMART tech inside the drives to set the fan speeds. It was rather expensive but worth the $35

    This plug pulls out straight up towards the top of the screen. That is, standing above the top edge of the screen, straight towards yourself. DO NOT pull it ‘up’ 90 degrees from the board it is mounted on! You will deflect it away from the board—like I did, after reading this vaguely written instruction for this part of the procedure….

    You can easily remove it by using two fingernails on either side of the plug to gently and slowly lever it out of the socket. BEFORE YOU DO, paint one side of it white or yellow, so you can re-install it properly….

    If you look at the connector, one side has two slots through which the gold connector pins are visible. This side is “up” (faces the screen) when reinstalling.

    Is it possible to use the DVD drive after installing the SSD, or is there no space left?

    Joel -

    Yes, it is possible. The SSD fits below the dvd drive; it doesn't replace it

    • Scollegare il connettore del cavo del sensore termico dell'unità ottica dal connettore femmina sulla scheda logica.

    This step is not necessary. I have problems with the pulling out, and found that it's not necessary to out it in this case.

    Steve -

    Agreed. Leave it plugged in and peel the buffer tape and temp sensor off the optical drive assembly while it's still in the computer.

    John Lavenia -

    What problems did you have?

    Toni Marmol -

    Don't do that! It's not necessary to pull the sensor cable out. And it cost me an hour to find out that it was this sensor cable and not the LCD sensor cable that made the fans spin at 3000+rpm. The less sensor cables you remove, the easier to find the culprit if you stumble into fan issues.

    • Inserire un inseritore fra il connettore dell'unità ottica e quest'ultima.

    • Ruotare l'inseritore per separare leggermente il connettore dall'unità ottica, quindi estrarre il connettore dall'unità con le dita.

    Hello, is the sata & power cabla from the mac can directly feet inside the SSD?

    Roman Quenin -

    Can the superdrive connector cable (possibly just SATA and SATA power bundled) be used for SSD? I wanted to replace the superdrive completely with an SSD, and thus having in total 2 SSDs and one HDD inside the iMac. Thanks in advance.

    Krisna -

    There is another SATA connector on the back side of the logic board for an SSD.

    • Sollevare leggermente il bordo sinistro dell'unità ottica ed estrarla dal lato destro del case esterno.

    • Durante il rimontaggio, ricordati che ci sono due fori nella placca del lettore CD, nei quali si devono infilare due perni in plastica per posizionarla correttamente.

    • Sollevare la parte del nastro di alluminio evidenziato in rosso, lasciando la parte restante aderente alla staffa di plastica nera dell'unità ottica.

    • Non è necessario rimuovere completamente il nastro EMI dalla staffa dell'unità ottica.

    Found it easier to remove the four screws in step 16, then rotate the drive out of the plastic frame so the tape acts as a hinge, making it easy to peel the tape. This also eliminates step 17 as the tabs vacate their slots as the drive is rotated.

    • Se hai un disco o altro incastrato nella tua unità ottica, abbiamo una guida per risolvere il problema.

    Do I have to reattach the optical drive thermal sensor to the SSD?

    Ignatius Lee -

    Yes, just stick it onto the SSD and cover it with the buffer. Better than leaving it loose in the computer, or worse omitting it altogether.

    John Lavenia -

    looks like you cracked the edge of that sensor :)

    Replacing an HDD was easy as PIE compared to this, the replacement Superdrive's holes did not line up the same way the original did. The original was a Sony drive, the replacement was made by H-L. But the shape was the same. By holding the bracket in place with my hand I was able to worm two screws in sideways until the pressure lined it up, then I was able to get the rest of the bracket screws back in. I had to do that while making sure the little tabs in the front of the drive were orientated properly - And not messing up the silver tape much. After that it was all relatively easy. The instructions were spot on and for the exact iMac (11,1) I was working on. The replacement Superdrive works perfectly despite the Brand change, I installed Bootcamp to make sure- It read and installed from my Windows 7 install DVD, NO Problem. I set the monitor screen in place without screwing it all back in just in case I had to open it back up again, not needed. Thank you SO much for your easily understood instructions.

    I had it easy with replacing dead optic drive in 2011 27" with a 2010 27" optic drive so did not even have to take the optic drive out of its holder. Now I have an internal dvd super drive again. Thank you ifixit.

Great tutorial. The recommended T10 Torx Screwdriver was too big - I had to use a T9.

Also, it isn't necessary to unplug the optical drive thermal sensor connector socket on the logic board (Step 10), I just disconnected the optical drive thermal sensor from the drive (Step 17) before removing it.

Awesome guide! I bought your suction cups for the front glass, and a toolkit, along with a 2TB HDD to replace the original 1TB drive. It was easy to replace both the optical drive and the HDD with the right tools and this very detailed guide to follow. I have had no problems with the internal cooling fans running fast with the new HDD either. It all came apart easily and seems to have gone back together without any problems as well. A huge help! You saved me several hundred dollars in repair bills. Thank you!

Great guide, it worked perfect for me. Thanks!

I have seen another instructional video I have replaced a HD in an Imac 27 I have all your tools thing is this can be done in my opinion with the computer in its standing position and I will do that for the optical drive soon

Left a comment in the other area too, I used this guide and another linked to it to replace both an HDD and the Superdrive. Perfect Instructions - I was daunted by this task the moment I opened the iMac, but these instructions made it doable. I also replaced the HDD and the Superdrive while in standing position. All I needed were a bunch of Pill Bottles for the screws, my cheap precision ratchet screwdriver set which had the proper size Torx Screw Bit, and an old iPhone Toolkit which had the rest of the things I needed. I used a Palette Knife to remove the sensor. The hardest part is getting the Screen screws back in, because the magnets make it difficult. I can probably do this now with other Model iMacs- This was the second iMac I used your guides to replace the HDD, this was my first Superdrive. Thanks a LOT.

Merci grâce à votre tutoriel, j’ai pu remettre en état de marche mon iMac 27” de 2009.
