Introduzione

Segui i passi di questa guida per aggiornare o sostituire l'hard drive nell'iMac Intel 21.5" EMC 2889. Nota che se stai aggiornando il tuo disco, dovrai clonare il tuo hard drive attuale su quello sostitutivo prima di eseguire questo aggiornamento, per mantenere i tuoi file e il sistema operativo.

    • Con il cardine libero di muoversi, l'iMac sarà sbilanciato e la lavorazione risulterà difficoltosa. Le riparazioni saranno più rapide e facili con un cuneo di supporto per iMac, ma potranno essere completate anche senza di esso.

    • Se intendi usare il Cuneo di cartone di supporto dell'iMac di iFixit, segui queste istruzioni di assemblaggio per montarlo.

    • Prima di iniziare a lavorare sull'iMac, scollega il computer dall'alimentazione e tieni premuto il pulsante di alimentazione per 10 secondi per scaricare i condensatori dell'alimentatore.

    • Fai molta attenzione a non toccare i contatti dei condensatori o qualsiasi punto di saldatura esposto sulla parte posteriore dell'alimentatore. Maneggia la scheda tenendola solo dai bordi.

    The wedge is an extremely tight fit for this model. I was worried that the amount of force needed to use it as shown might damage the stand, so I used it with the long side down instead. It worked fine that way and didn’t need anywhere near as much force to insert.

    Here are a couple tips from me:

    1) Expose the adhesive to extreme temperatures. I did this by transporting my iMac in my car, screen-down on a piece of cardboard on a cold February morning (in Chicago). When I went to pick up the iMac, the screen practically fell off the chassis. I would have been distraught by this if I hadn’t already planned this replacement. So it was a happy accident.

    2) Remember to expell the residual power from the power supply by pushing the power button while the iMac is unplugged. This does NOT guarantee it’s safe to touch, but when I accidentally brushed the solder and exposed capacitors, I didn’t get shocked.

    jerrid_foiles -

    Instead of using the wedge, I placed the iMac faced up with the top side (web cam) facing me while I ran the pizza roller around. It worked out great!

    Sam Fung -

    “All iMacs also come with a traditional hard drive” mine doesn’t!! it’s HDD bay is completely empty, no SATA cable or anything. I guess I’ll have to upgrade the PCIe SSD instead.

    Chris Hughes -

    There is no replacement glass for this model, it is part of the LCD and impossible to remove or replace- the entire LCD has to be replaced unfortunately if the glass is cracked or damaged. You will have to Google search for a replacement. Also be careful with some of the lock tight tork screws as I broke one of my screw mounts taking one out.

    Phil Tesone -

    I used this service wedge but also found it a very tight fit. The same stabilization can be achieved by using a big rolled up towel.

    Ernst -

    While this is a good instruction guide, I recommend to also look at OWC’s instruction video about drive installation, before starting the exercise. Those install videos are very detailed and useful.

    Ernst -

    Main advice: TAKE YOUR TIME with the pizza roller.

    Make several passes, until you really feel like there's no more sticker in the way. Stay away from the camera though (approx. 1inch / 2.5cm on both sides). This will reduce the work left with the plastic card. Adhesive is really on the edge of the screen so there is absolutely no need to go any further than the recommended 1cm / 3/8inch depth.

    Where are the sensitive parts?

    Facing your iMac, imagine you're looking at a watch. There are antennas on 1, 2 and 4 o'clock. Do not insert any metal piece there (nor anywhere else, btw). Other than that AND the screen cables underneath the camera, not much danger.

    • Iniziare sulla parte sinistra del display, accanto al pulsante di alimentazione, inserire l'attrezzo per l'apertura dell'iMac nello spazio fra il pannello di vetro e il case posteriore.

    • Il perno sull'attrezzo per l'apertura dell'iMac impedisce di inserire la ruota troppo a fondo. Nel caso di utilizzo di un altro attrezzo, non inserirlo nel display per più di 0,95 cm, In caso contrario, si rischia di tranciare i cavi dell'antenna e provocare danni gravi.

    Don’t get too worried about starting exactly where the picture says. The glue is stronger in some parts so just start wherever is easier and then work slowly and patiently around in the direction shown.

    Richard Cook -

    As this guide doesn’t cover replacing the adhesive strips, I found referring to the following was useful (noting that it’s not for the same model of iMac, so the modification they mention wasn’t necessary): Sostituzione strisce adesive iMac Intel 21.5" EMC 2544

    Alan Digby -

    It is very easy to crack the glass in front of the LCD during this step. I used the guitar pick, maybe it was too thick… crack is just on the frame but anyway it is disappointing :(

    Nikolay -

    This part of the exercise should be done with extreme patience. I took my sweet time with the opening tool, rolling it through the entire panel and enclosure gap over and over again, until I was very sure no parts were sticking together anymore. And when I thought I was I done, I decided to do it over again.

    Ernst -

    You can "warm up" the adhesive before try to cut it with the tool using a hair dryer. Heat the edges for about a minute, keep moving it so you don't cause stress in the glass. Also the above note.. use the tool and then the cards. Do not use a guitar pick or other objects as the thickness will cause you to break the front glass, which is a bonded part of the display (expensive).

    • Utilizzare l'attrezzo come una taglierina per la pizza: ruotarlo lungo lo spazio per tagliare la schiuma adesiva al centro.

    • Effettuare sempre una pressione con l'impugnatura dietro il disco tagliente. Tirando, il disco potrebbe uscire dall'impugnatura.

    • Far scorrere l'attrezzo lungo il lato sinistro del display.

    If re-opening a screen that was opened and re-attached using iFixit’s adhesive strips, I would strongly recommend heating it first with an iOpener, heat gun or hair dryer. 20 minutes after attaching with the iFixit adhesive I tried to open it again with the pizza slicer to fix something and cracked the screen on the left-hand side.

    • Continuare lungo la parte superiore del display.

    • È consigliabile far scorrere ripetutamente l'attrezzo avanti e indietro lungo la parte già tagliata, per fare in modo di separare il più possibile l'adesivo.

    In this step can I cut along the display without make any damage to the front camera?

    arisnordico -

    Hi! Actually - there is no need to cut the tape around the camera area - there is no tape to cut at all! And so, the way go is easy - just pass 10 mm to the left and to the right from camera and start cutting!

    P.S. Just did the whole procedure to replace a RAM and to add SSD on PSIe an hour ago! Seems to be different reading the instructions... you know - 2/10 and so on. But it's really not that hard, trust me. I'll give it 5/10.

    P.P.S. By the way there is one trick to pass the difficult steps. Any action which requires pulling smth (motherboard, speaker, power supply unit) from the narrow crack (or should i say - slit?) at the bottom of your Imac is really not so easy.

    And the trick is to first remove a thin metal stripe with some kind of insulation on it which held by 5 small (very small!!) screws at the bottom of your Imac. After you done it - it's easy to pull everything! Pay attention to the fact that one of this 5 screws at the center are more shortly than others.

    I did all steps like this manuell but now the Display wont work only some colered strips are to see! Whats happend??

    Can anybody help me ? Maybe the connector cable is broken?

    djfanta -

    Check both connectors, probably one of them not seated well

    pzhivulin -

    You can add a SATA SSD if you already have a PCIe SSD Factory?

    kaserlik -

    If you're changing cracked EMC 2638 display to new assembly, there's two more steps:

    Step 24: Use the tip of a spudger to flip up the metal retaining bracket on the display data cable.

    Carefully pull the display data cable from its socket on the display assembly.

    Step 25: Use the tip of a spudger to unplug bracket of the thermal sensor small cable near display data cable.

    Carefully remove scotch tape covering thermal sensor. Using iSesamo or flat tip of the spudger carefully peel the thermal sensor away.

    pzhivulin -

    omg - forgot to switch the termal sensor from the old display...

    now fan runs like crazy...

    Andrei Balotescu -

    The key thing is to never put any force on the opening tool when working through the tape. Just roll it back and forth with ease.

    • Terminare l'applicazione dell'attrezzo per l'apertura nella parte inferiore del lato destro del display.

    • A questo punto, si consiglia di ripassare nuovamente l'attrezzo lungo tutto il display, per fare in modo di tagliare il più possibile l'adesivo.

    Yes, do it many times to loosen the adhesive.

    Noah Ralston -

    Would be good data to show the 3 areas (wifi antennas where the "tape" is larger and covers them. The rest of the "tape" is 1.4" and easy. Also after removing the display, be sure to remove the old "tape" from both the display and the rubber parts of the case. Use the spudger to start an end and it should pull off easily. Careful on the baackside of the display as you can scratch off the black paint/covering.

    • Sebbene l'attrezzo per l'apertura tagli la maggior parte dell'adesivo, il display sarà ancora leggermente attaccato al case. Occorre una scheda di plastica per liberare la parte restante dell'adesivo.

    • Poggiare l'iMac su un tavolo, rivolto verso l'alto.

    • A partire dall'angolo superiore destro dell'iMac, inserire una scheda di plastica fra il display e il telaio.

    • Fare attenzione a non inserire la scheda di plastica per più di 0,95 cm, in caso contrario si rischia di danneggiare i componenti interni.

    this step is extremely important NOT to stick in the cards too far….. doing so, you risk a 600 euro replacement as I experienced………

    Edgar Broekema -

    I drew a 3/8” line on my cards with a marker first.

    Max Romano -

    I’m reading this on the EU store, please change all measurements to cm/mm.

    Morgana Devina -

    @ifixit The next batch of cards you create should have a line printed on the card 3/8” in from the edges. Would make a nice reference.

    Richard Giratd -

    Here’s where OWC provides glass removal suction cups, which is a better solution than plastic cards.

    The suction cups help to easily lift the glass panel, without risking the damaging of any internal wiring that the plastic cards could cause.

    Ernst -

    Better to remove stand wedge at this point? Can’t see from pics

    • Ruotare delicatamente la scheda di plastica lateralmente per creare uno spazio fra il display e il telaio.

    • Eseguire movimenti lenti, facendo attenzione a non fare troppa pressione sul vetro del display, poiché occorre solo uno spazio di circa 0,63 cm.

    This part must be done very carefully or you can damage the flat cable from display, despite it was under a iron cover.

    • Far scorrere la scheda verso il centro del display per tagliare il resto dell'adesivo lungo l'angolo destro dell'iMac.

    • Occorre fermarsi prima della fotocamera iSight per non danneggiarla.

    You don't need to do it like this, simply open the iMac bendidng the LCD completely and use the pizza cutter to remove the adhesive.

    Felix -

    Using glass removal suction cups will avoid running this risk of damaging the camera (or any wiring).

    • Mantenendo entrambe le schede di plastica inserite vicino agli angoli come indicato, ruotarle delicatamente sui lati per aumentare lo spazio fra il display e il case.

    • In presenza di sezioni ancora incollate che non si separano, fermare la rotazione e utilizzare una delle schede per tagliare l'adesivo restante.

    • Iniziare a sollevare la parte superiore del display dal telaio.

    • Sollevare il display di pochi centimetri, poiché i cavi di alimentazione e dei dati sono ancora collegati alla scheda logica.

    • Solleva lo schermo abbastanza in alto da avere un accesso facile al connettore, ma non tanto da strappare i cavi e forzare i rispettivi connettori (alzalo di circa 20 cm).

    • Mantieni lo schermo con uno mano mentre con l'altra stacchi il cavo di alimentazione dello schermo .

    It was difficult to remove this connection. I ended up having to gently pull-up vertically a little on the wire side to unsnap it about 1mm and then horizontally wiggle it out.

    I had a difficult time removing this connection. I had to lift the wire-side about 1mm before it unsnapped and then carefully wiggle it out horizontally.

    delacrj2 -

    Can this cable be replaced? I am worried mine is damaged. I have no display after the screen fell and stressed the display flex cables following an SSD upgrade.

    Jeremy Brainard -

    This step should be done with extreme caution and care, as this step 19 is not described in great detail (sorry, author).

    The first (most outward) cable will slide out by gently pulling it by its tabs. The second (inner) cable is more tricky, as the locking lever must be moved backward first, before gently pulling backward on the cable connector. The angled tweezers are useful here, to help lift that locking lever, because fingers are too big for this.

    Ernst -

    be VERY careful and SLOW...take your time. These displays crack VERY easily when removing and they'll spider web on you. I've done probably 20 or so of these and cracked 3 being super careful.....ugh.

    Faslane -

    I found the best way to unplug this display power cable was to use my right hand, and the fingernails of my index finger and thumb to grab the ends of the tabs on either side of the connector, squeeze, and pull the connector out gently.

    Phil McInnis -

    i think the cable nearest the case edge is held in by friction and can be gently pulled, maybe with fingernails or a spudger. The next cable is held by a wire lever clip as described above it unlocks so the cable can be removed. These cables are also fiddly to re-insert, I didn't get one of them home and had no display after power-up, so at the end, don't re-seal the screen until tested.

    • Continua a tenere lo schermo con una mano, sblocca la staffa metallica di ritenuta del cavo dati dello schermo.

    • Stacca con cautela il cavo dati dello schermo dalla sua presa nella scheda madre.

    • Assicurati di tirare il cavo dati dello schermo direttamente fuori della sua presa, mantenendolo parallelo alla scheda madre, per evitare di danneggiarlo.

    Cannot seem to find a replacement cable for this, as I suspect mine is damaged. Can’t even find a part number. Anyone know what it might be?

    Jeremy Brainard -

    https://www.amazon.com/gp/product/B08TTL...

    That's the part I ordered for mine and it seems to work ok. I did make a point of contacting the seller and advising them of my requirement and they ensured I got the right part and it matches the description of the link. Bear in mind I bear no responsibility if yours does not work since I am just sharing what I did and what I ordered. Thanks.

    Jim Stanford -

    I also need that cable.

    cameronjpu -

    It's a little difficult to tell... but looking at the connection to the logic board on the video data cable, are the pins faced up or down?

    On the display, same question since it appears you have to "twist" the cable during the reconnection step.

    Jim Stanford -

    For this particular cable, take a good look before pulling on anything. Plug is locked on its socket with a bracket. You can lift this bracket by holding the small, flat black plastic handle that is attached to it. If you're struggling to grab it, use the end of the pizza roller handle to lift it, or the tweezers. Cable then comes off by pulling parallel to the main board.

    Froggy Manny -

    How can I tell if either of this cable is bad? My iMac display won't turn on after reconnecting it. I'm using an external display and everything is working except for the iMac display. If I go to settings - display the built-in display is recognize. But again nothing shows up in the screen - not even the apple logo when turning it on.

    • Solleva lo schermo in posizione all'incirca verticale.

    • A questo punto c'è ancora una striscia di adesivo lungo il bordo inferiore dello schermo che tiene ancorato il display alla scocca come se fosse una cerniera. Puoi indebolire questo adesivo muovendo lo schermo su e giù per alcune volte di seguito.

    The adhesive strip along the bottom is designed with a pull tab on each outer end. Rather than lever and pull the screen simply carefully pull the tab which removes that half of the lower adhesive strip and frees up the screen.

    Andrew Stephens -

    Yes, use the tabs as Andrew indicates. Super easy.

    • Fai attenzione a non toccare i conduttori del condensatore o le saldature esposte sul retro dell'alimentatore (in rosso).

    • Afferra la linguetta all'estremità di una delle strisce adesive del bordo inferiore dello schermo e tira l'adesivo verso il bordo superiore dell'iMac per rimuoverlo.

    • Ripeti questo passo con l'altra striscia adesiva e rimuoverla.

    • Se una delle strisce adesive si rompe prima di essere rimossa, usa una scheda di plastica per tagliare l'adesivo rimasto.

    • Solleva lo schermo dalla scocca e rimuovilo dall'iMac.

    • Può rendersi necessario sollevare lentamente il display da uno dei bordi laterali per staccare l'adesivo rimasto.

    • Stai molto attento nel maneggiare lo schermo: è grande, pesante e di vetro.

    • Dopo aver tagliato l'adesivo, non può essere più riutilizzato per rimettere al suo posto il display. Segui questa guida per sostituire le strisce adesive che fissano lo schermo alla scocca.

    The adhesive strip along the bottom is designed with a pull tab on each outer end. Rather than lever and pull the screen simply carefully pull the tab which removes that half of the lower adhesive strip and frees up the screen.

    • Rimuovi le seguenti viti Torx T10 che tengono ancorato il supporto del'hard drive sull'iMac:

    • Due viti da 21 mm

    • Una vite da 9 mm

    • Una vite da 27 mm

    At step 26, when reassembling, it's super easy to over-tighten the 9mm screw and strip the brass ferrule out of its hole in the plastic bracket (%#*@).

    Charlie -

    buongiorno, l'imac del 2019, non monta alcuna ssd, ma monta una m2 direttamente sulla scheda madre!

    pertanto nella guida andrebbe aggiunto il cavo sata con sensore temperatura da aggiungere sulla scheda madre, per poter collegare un nuovo hd ssd altrimenti rimarrete come me bloccati con un imac aperto e non assemblato, in attesa di ricevere il cavo acquistato su internet da amazon o terze parti.

    vi consiglio inoltre di aggiungere una foto reale del ò'imac 2019 nella guida in cui manca l'ssd, renderà subito la problematica che avranno in molti!

    • Usa uno spudger per disconnettere il singolo cavo SATA spingendolo con delicatezza lontano dal disco rigido.

    • Rimuovi l'hard drive dall'iMac.

    I’ve found that loosening the T10 screws on the enclosure to the left helps give some room to remove and reinstall the drive. Otherwise reattaching the SATA cable can be a hassle.

    rothgar -

    Not only is it useful to loosen up the speaker next to the SATA connector I found it helpful to use a pen to mark the exact location of the edges of the SATA connector on top of the new drive, so I could guide the connector in place. It also helps to put the bumpers in after you get this SATA connector in place.

    bsmith1 -

    Waiting to put the bumpers on until after the SATA cable is attached was a must! Also loosing the speaker and moving over a couple centimeters was a huge help. Thanks

    • Stacca la protezione gommata da un lato del tuo disco fisso.

    • Ripeti l'operazione dall'altro lato del disco fisso.

    • Quando installi un nuovo disco, e' utile utilizzare un nastro biadesivo per attaccare le protezione al tuo nuovo disco.

    reconnecting the new drive can be a little tricky as the sata connector in the Mac is hard to align. I found that it helps to move the end of the bumpers out of the way, then push them back into position once the drive is connected.

    Gareth Jones -

    Thank you for the tip!

    Michael Gagne -

    thats what it did as well, thx for the hint. also i used a plastic spudger to reconnect the plug unto the new drive and leveled it against the speaker casing thats so close to the drive bay

    Yes you can install ANY SATA SSD.

    And no … there is no thermal sensor on the drive. You don’t need them on these models.

    Did you ever find out if you could replace your 500 GB with that Firecuda? I’m looking at doing that. I need more storage for my 500 GB photos library and don’t want to pay so a ton for the SSD that is big enough.

    shippster -

    where is the guide for the follow up ?

    installing a new hard disk and closing the screen back up.

    The SSD was a HUGE performance boost over the 5400rpm drive my iMac came with. If you’re pulling your hair out because Lightroom has become excruciatingly slow, upgrade your hard drive to SSD. You will not be disappointed.

    The kit has everything you need. Follow these instructions carefully and you’ll be fine.

    Mike Mullis -

    Huge improvement! It’s like a new machine. Highly recommended upgrade.

    Take care with the adhesive strips, and don’t forget to set new SSD as the boot disk (System Preferences, Startup Disk) after you’ve tested its bootable.

    I previously had a fusion drive and installed a SSD. Will there be any issues with the ssd portion of the fusion drive? I still see it there in disc utility. Also, I’m showing two SSDs, along with the 32 gig one. Is that correct or did I create something that shouldn’t be there?

    rossmueller -

    I have this same question. I’m showing 2 drives but 1 is grayed out on the computer screen when I click on it nothing happens.

    Frank -

    A fusion drive combines two physical disks via software to act as one. It it something that has to be done manually and expressly. When you first got the computer, your fusion drive combined disks A (SSD) and B (HDD). If you replaced B, then you probably have an unused 32 GB blade SSD along with your new SSD. It possible to create another Fusion drive, but you’d have to start from zero, because creating a fusion drive erases the individual disks completely.

    also, not 100%, but I tried for several hours the other day and I’ve come to the conclusion that my version of Big Sur (11.1) doesn’t support Fusion Drives. Correct me if I’m wrong. Or maybe it’s because I’m running Big Sur on an unsupported iMac.

    David -

    It is also possible install the bumpers after getting the drive cable attached. This gives you more room to work with the cable and drive.

    Sean Kane -

    The hardest part was to plug the connector into the new SSD. I loose the two screws of the adjacent (left) speaker and move it just enough to have sufficient space to introduce my fingers to push the conector into the SSD. Left the replace of the rubber bumpers after reconnect the SSD, is easy to handle without it.

    Dennis Salas -

    I bought Samsung QVO 1TB SSD and now the fan is blasting fast and loud. So if these don’t use the thermal cables then what seems to be triggering the high temp? Obviously it’s the hard drive but could it be that the drive was cloned? I’m kinda stumped, I know I can control with software but some of you are saying it should run normal after install. Thanks for the info.

    Is there a PCIe slot for an SSD instead of the SATA 3.0 2.5”?

    thank you,

    deejaysurfer -

    Not unless your iMac shipped with a Fusion drive or SSD.

    roberttrevellyan -

    The step-by-step guide was awesome and easy to follow. As others have commented, getting the SATA connector onto the SSD is tricky but not impossible. Just pull back the rubber bumpers long enough to reach the connector, then flip them back into place before seating the drive. One comment for my machine (late 2015 21.5”): There is no mic hole for my model, so while I was a little confused at the instructions on reinstalling the adhesive, the drive replacement went like a dream. And I saved myself the $120 labor the local Mac shop wanted to charge me.

    Glenn Pettit -

    Hat alles prima funktioniert. Leider läuft der Lüfter jetzt auf 100% und kernel_task Prozess ist bei über 300%. Was habe ich falsch gemacht. Diagnose meldet jetzt einen SMC Fehler und CPU-Proximity liefert keinen Wert.

    Kann jemand helfen?

    Michael Schmitz -

    schau doch mal hier https://apple.stackexchange.com/question...

    This is the least accurately described step (sorry, author). While removal is easy, inserting the new drive in its place is a bit tricky. The key here, is to insert the new drive with its rubber bumpers back in its space, so that it is fully seated down in its place *before* the connector can be re-attached. Once it is seated in place, use the flat end of the spudger to gently manoeuver the connector back into place until it is firmly connected to the drive.

    Ernst -

    Reassembling the iMac is not simply following these instructions in reverse order (sorry, author).

    Before embarking on the home stretch, it is very important to carefully study the guide about the Adhesive Strips Replacement (iMac Intel 21.5" Retina 4K Display (2017) Adhesive Strips Replacement - iFixit Repair Guide), as this a tedious and time consuming process. Perfect alignment of those adhesive strips takes some concentration, because you will want to have your display panel back nice and tight and fully aligned with the case. Once all strips are in place, the 2 display connectors need to be gently reattached to the motherboard, before closing up the panel. I took my sweet time for that step, and thankfully have a perfectly aligned display panel back in place looking no different from the factory fit.

    I got a 4 TB Seagate Barracuda HDD as a replacement for a client. (Going for capacity over speed.) Does anyone know if it will fit? It’s definitely fatter than the other HDD/SSDs I’ve installed before.

    David -

    There needs to be more added to cover the first part of re-assembly. To connect up my SSD, I needed to remove screws that held in place the black plastic to the left of the drive bay. This was only way to get the added space needed to connect the SSD to the drive cable. I also connected the SSD first, then attached the rubber bumpers, simply to give me more room to maneuver the drive next to the connector. All in all, yes, a person well familiar with tearing down iMacs could do it in an hour or so. But frankly, the design of this iMac is a total horror show when it comes to repair or replacement of parts, especially given its reliance on glue and adhesives. Gee, just like other Apple products.

    Ben Myers -

    Ben, after you replaced the HDD with SSD, did you have any fan issues on the A1418 model iMac? Thinking of doing this but I’ve been reading for hours and seeing mixed reports about thermal sensors.

    Christopher Henley -

    This iFixit tool (iFixit Opening Tool) will be your best friend when it's time to install your new 2.5" hard drive. Simply hook the tool to the back top corner of the iMac SATA adapter, connect your hard drive loosely to the SATA ports and use the tool to pull the SATA adapter forward into the hard drive.

    iannai29 -

    After replacing the hard drive. All went well BUT -now my mic does not work. It's the single hole on the bottom. Any ideas anybody?

    Paolo Alberto -

    Did you notice step 14 in the guide to replacing the adhesive strips?

    roberttrevellyan -

    Please update the end of this guide, pointing the customer to the guide for replacing the display adhesive strips. You provide a single kit for this procedure, and the customer has to figure out that they must follow two independent guides, in order to successfully complete the installation.

    Ich habe den unteren Klebestreifen gar nicht gelöst! --> Monitor (Glasscheibe) nach vorne auf ein dickes Kissen gelegt - so dass das Glas nur ca. 80° Winkel nach vorne zu liegen kommt und dann habe ich die Festplatte getauscht! So konnte ich die untere Klebeleiste wieder verwenden und hatte genügend Platz um die senkrechten und oberen Leisten zu verkleben! ⏎
    Tip: Klebestreifen zuerst auf dem Alugehäuse befestigen......

Well done and thank you for this very precise description to access the hard drive. After that, reconnecting the hard drive or SSD is difficult because the very short SATA connector wires do not allow it to be presented well in the axis of the drive connector and it is impossible to hold it firmly with your fingers. Space is very small.

Hubert Despré -

Thank you SO MUCH for this guide. I bought my iMac used from someone who was upgrading to a newer SSD model, and once I got it home and reset, I was understood all too well why he upgraded. So I ordered the kit here and followed these directions. With my iPad propped up next to the iMac on my table, I was able to follow it right through. As others have commented, the drive cable is very short, but I held back the rubber bumpers until I got it connected, and then everything else went smoothly. Now my iMac is like a new machine (minus the newer Thunderbolt ports and other newer amenities). Thanks again!

Glenn Pettit -

I was just looking at the dismal trade in options for all my old apple products, and just assumed Id be buying a new computer every 2-3 yrs at retail whenever apple decided mine was out of date, but after stumbling on this site i love the mission, and am actually excited to try some of these articles on my old products and maybe learn a few things. Thank you for all this work its awesome and appreciated.

Christopher Pina -

Can someone explicitly answer if the Temperature Sensor is need for this model? The internet says yes, but the space inside says no.

Thurston -

I’ve the same question Thurston made. I’m planning to upgrade to a SSD but I’m worried about thermal sensor and the kernel_task issue some that some people mention. Is there a solution? This should be a concern?

Leonardo Lellis -

Thanks for this great manual.

I recommend loosing the screws on the left speaker to connect the new drive. It just gives some more space to connect the SATA port.

Anton Krackhardt -

Does someone know about the Thenal Sensor issue?

Hans Popp -

iMacs which require a thermal sensor cable:

2009-2011 21.5” and 27”

2012 and later 27” only

The thermal sensor cable for 2009-2011 and the one for 2012 and later 27” iMacs are different from each other. The 2009-2011 cable has one end with a 90 degree connector.

iMacs prior to 2009 do not need the OWC thermal sensor cable.

For those requiring the thermal sensor cable, both HDDs and SSDs require them.

Dale Forbes -

I have a iMac "Core i5" 2.8 21.5" (Late 2015). Will this require the thermal sensor cable or additional software?

Thank you

The question immediately above relates to replacing the original hardrive with a SSD.
