    • Se la spatola è stata acquistata da iFixit.com, è possibile saltare questo passaggio. Le spatole vendute da iFixit hanno i bordi già sottoposti a molatura.

    • Per aprire il case, occorre una spatola. Una spatola sottile da 3,81 cm è l'ideale, tuttavia occorre levigarne il bordo. Strofinare il bordo corto della spatola in avanti e all'indietro su un foglio di carta vetrata a grana grezza (da 100 è ottimale) finché non si ottiene un bordo levigato.

    I used a tool for opening the back of watches to replace the battery (the type that have the non screw-on backs). Worked fine!

    IMHO there are many steps not necessary. The guide is very good but i can't find the reason for steps 7-15. It is all about freeing the internal frame. As far as i know it is enough to remove the antennas and the 4 screws holding the optical drive?!?!

    • Inserire con attenzione una spatola nella fessura fra il coperchio superiore e l'alloggiamento inferiore. Iniziare dal lato sinistro. Premere la lama finché non si avverte una certa resistenza (circa 0,95 cm).

    • Allargare delicatamente la fessura facendo leva sul manico della spatola verso il basso e lontano dal Mac mini.

    • È consigliabile iniziare dal centro e quindi procedere lungo il bordo finché l'alloggiamento inferiore non si sgancia leggermente.

  3. ICQlx2LJIi3i5DWr

    • A questo punto, inserire la spatola nella fessura sul lato dello slot dell'unità ottica del computer.

    • Far pressione sulla spatola verso il basso, mentre si opera lungo il bordo del Mac mini, finché l'alloggiamento inferiore non si separa ulteriormente da quello superiore.

  4. DVYVrvGA3cTpItRn

    • Ripetere la medesima procedura indicata nei passaggi precedenti per il lato destro del Mac mini.

    • A questo punto, attorno al perimetro del Mac mini, dovrebbe essere presente una notevole apertura fra gli alloggiamenti superiore e inferiore.

    • Capovolgere il Mac mini.

  5. VPN5xWMbATEaIwmV

    • Sollevare delicatamente l'alloggiamento superiore dal Mac mini e conservarlo altrove.

    • Potrebbe essere necessario inclinare da una parte e dall'altra l'alloggiamento superiore durante il sollevamento da quello inferiore. Se le linguette si bloccano sull'alloggiamento superiore, liberarle mediante la spatola.

    For reassembly, test your Mini before replacing the cover. This could save time, should the test reveal problems.

    • Più avanti nella guida, occorrerà rimuovere diverse viti con testa a croce incassate. Di solito, i portapunta sono troppo grandi per entrare negli incassi, pertanto accertarsi di avere a disposizione un cacciavite con testa a croce sottile e con albero.

    • Per prima cosa rimuovere l'antenna AirPort (la più grande delle due), in prossimità del pulsante di alimentazione.

    • Premere leggermente le due linguette di fissaggio l'una verso l'altra e sollevare l'antenna AirPort dal proprio alloggiamento.

    • Premere eccessivamente le due linguette può spezzarle dal telaio interno, pertanto operare delicatamente.

    • Durante la reinstallazione, occorre premere leggermente le due linguette affinché si adattino alle aperture sulla scheda dell'antenna AirPort.

    • Utilizzare la punta di un inseritore per sollevare leggermente il lato sinistro del bloccacavo ZIF dal rispettivo connettore femmina.

    • Il bloccacavo ZIF si solleverà di circa 1 mm per poi arrestarsi. Non tentare di rimuovere completamente il bloccacavo ZIF.

    Now also lift the right side of the ZIF cable lock up from its socket.

    Good catch of the incomplete unlocking instructions. ;P

    lamarhavard -

    Hmmm... what if I didn't read this before and I removed the cable and the lock sort of broke?... what would happen... would I experience problems? I can still put the cable back in place and push the lock back down with the spudger.

    Dan O -

    Same. I totally removed the lock , the edges are busted and won't stay in place, How can I get the cable to stay? what's the fix?

    Suzanne -

    Dan O & Suzanne, hold the cable in the socket and put a dab of hot glue on both sides, It's non-conductive and should hold...worked for me.

    lamarhavard -

    does any one know, where to get the connector from zhe ZIF Cable?

    someone, that preowned my mac broke the holder!

    julian gmeiner -

    Julian, did you ever find where to get a replacement lock for the Zip Cable. Mine is also broken..

    Suzanne -

    This is not my first memory replacement in a Mini and I got over-confident and stupidly fully removed the audio cable ZIF lock and assumed I had broken something. But, now that I have read this guide more carefully, I am not sure. I sure would love to hear some detailed instructions for putting a ZIF lock back on.

    Is it possible that I have removed it without having broken it? If I have broken it, do I have to buy a new cable? Just a new ZIF lock? A new audio board? This is a 2.0 GHz A1176.

    Thanks!

    GalvanicMacPro -

    Michael, Mine seems to be broken. I bought & tried the Kapton Tape that was suggested & still no sound.

    Suzanne -

    C’est la première que je doit déverrouiller un câble ZIF. Je précise qu’il faut lever à gauche et à droite, ça force un peu, prendre appui sur le boitier du Mac, comme e montre la photo.

    La partie noire reste dans la partie blanche (+1 mm), et la nappe flexible sort par le haut.

    • Sollevare il cavo piatto della scheda audio dal connettore femmina.

    • Se non si solleva dal connettore, il bloccacavo ZIF non è del tutto sbloccato. Verificare che sia sollevato in modo uniforme di circa 1 mm dal connettore femmina nella scheda di interconnessione.

    As an option to avoid potential damage when disconnecting the cable from the ZIF socket and clip, it is possible to unscrew the audio board and remove it along with the internal frame.

    • Ruotare il Mac mini affinché il meccanismo di caricamento dello slot SuperDrive sia rivolto verso l'utente.

    • Mediante un paio di pinzette, sollevare connettore del cavo del sensore termico del disco rigido dal connettore femmina sulla scheda logica.

    • Prendere il connettore con le pinzette (come indicato nell'immagine), ma non prendere i fili.

    • Il connettore si trova sotto l'apertura dell'unità ottica, accanto alla batteria PRAM.

    Managed to leave this connected by flopping back the drive rather than totally removing

    WATCH OUT!!

    separated one of the wires from the connector very easily. i would have preferred to use a spudger at this step. the tweezers in effect snipped the wire!!

    mklsvg -

    As my experience you should definitely use angeled tweezers as shown in several pictures. To avoid stripped cable deflash sharp edges of the tweezers a little bit. I never experienced problems when using that kind of tool carefully.

    Timpetou -

    I've had to remove a few of these connectors on iBooks and other small Apple devices ... I've found that, with careful and gentle pressure (working first one side and then the other) using a small flat-headed jeweller's screwdriver is best.

    Mike Haines -

    I agree Mike.

    dixieskettlecorn -

    Note where the airport antennae connecting wire comes out from the interior along the top. When reassembling, it has to be routed the same way, or it won't reach its install position.

    robert -

    If your fan runs at high speed after you complete this project, you have forgotten to reconnect the thermal sensor.

    • Nei prossimi passaggi, verranno rimosse le quattro viti con testa a croce che fissano il telaio interno al case inferiore. Ciascun passaggio comprende un'immagine riepilogativa che mostra la posizione generale e un primo piano sulla vite specifica.

    • Rimuovere la vite con testa a croce incassata accanto al pulsante di alimentazione, che fissa il telaio interno all'alloggiamento inferiore.

    • Rimuovere la vite con testa a croce incassata accanto alla spia della modalità sospensione, che fissa il telaio interno all'alloggiamento inferiore.

    • Delle quattro viti che fissano il telaio interno al case inferiore, questa è la lunga.

    • Rimuovere la vite con testa a croce dal telaio interno, in prossimità dell'antenna Bluetooth.

    Before removing any of these screws, there is another step needed which is not here:

    On the front of the optical drive, right side as you look at the slot-load, is a small blue board attached by a single black screw. This needs to be removed before the optical drive can be taken out.

    • Rimuovere la vite con testa a croce accanto alle porte audio, che fissa il telaio interno al case inferiore.

    On reassembly, if you don't have a magnetic screwdriver, a tiny dab of grease at the tip of your screwdriver will help hold the screw on the driver so you can lower it into the recessed slot.

    • Sollevare delicatamente il telaio interno dall'alloggiamento inferiore, facendo attenzione a non incastrare il cavo dell'antenna AirPort o altri cavi.

    • Potrebbe essere necessario tirare in prossimità della scheda di interconnessione per la separazione dalla scheda logica.

    At this point be careful that you don't pull out the Airport antenna ... but if you do, just check that it is back before re-assembling.

    Mike Haines -

    During re-assembly, the internal frame has to go in at an angle ... the back of the optical drive goes in first.

    This means that you can seat the fan cover correctly, but more importantly, there is an interconnect board on the back of the optical drive that must be firmly pushed back into its housing on the logic board.

    Mike Haines -

    Reassembly: Before slipping the main frame back into its place, refer to earlier photos, ensuring proper routing of the WiFi cable.

    Steve -

    If, like me, you pull the wire on the airport antenna free, it snaps back into place easily. The connector is on the extra card screwed to the motherboard that looks like it has a phone battery embedded in it. The connector is at the top of the 'battery'. This accessory card is the wifi card, so it makes sense that the antenna plugs onto this.

    • Estrarre contemporaneamente le linguette su ciascun lato del chip di memoria RAM, allontanandole dal centro. Queste linguette bloccano il chip in posizione. Sganciandole, il chip "salterà" fuori.

  16. TyAYFjaA6mGdU2IS

    • Estrarre il chip di memoria RAM direttamente dal connettore.

    • Se sono presenti due chip di memoria RAM, ripetere la procedura precedente per il secondo chip.

    When (re)inserting RAM, the connector is tight - push firmly on both sides evenly - usually will "click" when fully seated. Look at the RAM connector edge - the gold should be almost completely within the socket (if not fully seated, it won't be recognized).

As a quick warning for noobs (that'd be me before I attempted this repair :P ), you need a matching pair of RAM (two chips the same size and spec). Otherwise, the computer won't boot up. ^_^

Skylar MacDonald -

There were 2x 1GB chips in my 2007 mini. I bought 1x 2GB chip, because I read somewhere that model only would allow 3GB. After replacing a 1GB chip with the new 2GB chip, the system is only showing 1GB RAM installed. Is this what you’re talking about? If I buy another 2GB chip, will it work? PC2-5300 2 GB RAM Chip

Jeff Box -

That is not always true. Often, perhaps…60/40, ish? My 2007 mac mini 2,1 is running one 1gb stick and one 2gb stick, a 500gb Kingston SSD and a salvaged superdrive from a MBP. I am tempted to try a core 2 quad or Xeon in it. For no particular reason than to see if it runs. anyone tried that one? I also had a 2008 mac pro 3,1 running four 2gb and four 4gb of under spec ram without issues.

In the 25 years i’ve been hanging out in server rooms, the client side of the working guidelines for ram matching has become less strict., but still, I believe, the ability to mix is in the manufacturing process. there’s no way but experience to be able to confirm that different makes, speed or size will function together. Unless of course stated in manufacturers documentation. The quality of the individual components will decide.

It will either work or it wont.

If you don’t have ram laying about, then your 100% right, buy matching pairs. otherwise, try it 'till it fires!

I successfully run 3GB in my A1176 Minis. When I put the 2GB chip in the bottom slot with the 1GB chip in the top slot, the machine would not boot and the power LED would blink continuously. When I put the 1GB chip in the bottom slot with the 2GB chip in the top slot, the machine works perfectly and sees all 3GB of RAM. (I don’t know if this is a rule or not, this is strictly my anecdotal experience.) I have *not* experienced installing 3GB and having the Mini run and only report 1GB. If you do that, I’d recommend checking to assure that the 2GB stick is seated properly.

I’ve also used 4GB without any trouble in A1176 Minis, but this model can only address a maximum of 3GB RAM. I have run performance comparisons between one equipped with 4GB and equipped with 3GB RAM and they measured identically. If you’re upgrading an A1176 from 2GB (equipped with a pair of 1GB chips) to 3GB, you can save a few dollars by just buying a single PC2-5300 2GB stick.

Mark B -

Thanks a lot, 1Gb -> 4Gb is done !

Eric Seigne -

This was easier than it looked, the only thing I had trouble with was getting the cover off (tried to use a flexible palette knife, bad idea) and getting the little sensor plug back in (it's SO tiny.) Oh, and one screw I had trouble getting back into the hidden recessed hole because my screwdriver isn't magnetized.

Speaking of which, size of screwdriver matters, I bought a set with a size 0 and size 000, but no 00, neither worked. Fortunately I had one of those cheap eyeglass repair kits, and the Phillips screwdriver worked perfectly.

Alexa -

The covers are the Worst….then and Now!!!

Stu Blair -

Thank you so much iFixit! Very nice guide. Followed and worked like a charm. Keep up the good info coming!

Eddie Abner -

Great step-by-step instructions, but now it won't boot... What to do?

John Nichols -

did you change ram

john korteman -

Great job, went like a charm. btw, the old Mac mini 2007 can accept 4 Gb, and it looks like it uses the full monthly according to the memory app I am using.

Some say t can't but how can I make sure of that, does any one knows?

Went from 2 towards 4 Gb, now my old iMac from the same year is most lightly the same hardware as this Mini and that one can hold 4 to 6 Gb.

Instructions along with comments worked well. Thank you. Tab of silicon grease very helpful on reassembly.

Excellent! Thanks a million! :-)

Sven Bornemark -

Nice equipment

Michał Szpak -

This update worked very well. Tougher to get apart than expected. My experience was that the prying tool is very flexible and bends. You are trying to find and push the plastic hooks inward slightly to release them rather than prying on the back housing. Also be careful with the Airport antena - it can pop off the connector from the interior pc-board. I didn’t find this out until I went to re-attach it and found he wire had popped free and I had to take out all the screws and and connectors and disassemble a second time to re-connect it! Fortunately ifixit has instructions on where that goes, thanks!

Will Snow -

that is so right. the prying is not good. the tabs, especially on a ten or more years old device, are brittle and the intake vents don’t leave much for them to be mounted on. I have broken a couple, when I was a Mac mini virgin.

there’s always that one screw/bolt/nut that gives you the gears. cars, macs, anything mechanical always has that one @#!@#@ fastener.

Stu Blair -

Thank you, it has worked very good!

Michael Westeroth -

Thank you! Works very well!

I found a pizza cutter is the best tool to separate cover from the bottom part.
