Introduction
La RAM est facilement accessible sur cet ordinateur et le travail de démontage nécessaire est réduit au minimum.
Ce dont vous avez besoin
-
-
Boîtier fermé, placez l'Unibody à l'envers sur une surface plane.
-
Appuyez sur le côté rainuré du loquet de déverrouillage de la trappe d'accès de manière à saisir l'extrémité libre du loquet. Soulevez le loquet de déverrouillage à la verticale.
-
-
-
Tirez sur la languette en plastique blanc et retirez la batterie de votre MacBook Unibody.
Great tutorial ! great step !

Retirez les huit vis suivantes par lesquelles le boîtier inférieur est fixé au châssis :
-
Une vis Phillips 3 mm.
-
Trois vis Phillips 13,5 mm.
-
Quatre vis Phillips 3,5 mm.
Make sure you have a good quality Phillips screwdriver. Mine had removable tips and had a small play at the connection. As a result I didn't have a good feel and damaged my screws (those securing the fan and the top left in step 23). Game over for me installing new thermal paste...
Be very carefull with your screws! Especially those on the inside.
You can get away with a Phillips #00 for many of the screws involved but the 4 at the bottom case split are likely to strip if you don’t use a JIS #00 or, in a pinch, a Phillips #000.
I used the Phillips #00 tip from my Pro Tech Toolkit, and it worked well enough. But yes, maybe #000 might have been better on the lower row of screws. Note to myself: Always read the comments first.
When replacing these screws, the order to replace them in is as follows:
1, Top left
2. Top right
3. Top center-left
4. Top center-right
5. Bottom center-right
6. Bottom center-left
7. Bottom right
8. Bottom left
I hope this information is helpful.
I followed my usual process of putting in all the screws loosely, then tightening them gradually in distributed pattern, to help ensure that the panel settles in place evenly. But maybe some orders are better.

En vous servant des deux mains, soulevez le boîtier inférieur et retirez-le du boîtier supérieur.
Thanks for the guide!
It's implicit in the two photos, but worth mentioning because it blocked my progress in this step for a bit: You have to put the release latch back into its horizontal, closed position before you can lift off the lower-case panel.

Écartez les deux clips de chaque côté de la barrette de RAM simultanément pour libérer cette dernière.

Lorsque la barrette de RAM se soulève, sortez-la de son emplacement en la levant bien droit.

Open back of unit, press two grey sides surrounding the chip, pull out the top (leave the bottom 2gb in) put in the new (4gb) chip; now there are 6gb of ram.
I just upgraded to 2 4GB chips. Works fine sofar!
That's awesome! I thought that I could only upgrade the RAM to 4GB (which is what I have now). Can you give me the type of RAM that you installed? I have this exact model MacBook.

Uh oh. I replaced my 2 1GB ram with 2 2GB. I turned it on and it beeps at me about every second, the front status light blinks in time, but nothing else....what next?
Sounds like bad RAM. I would contact who you purchased it from. If it was us, email support [at] ifixit [dot] com
I have used your guide several times, and appreciate how clear you are. I found that my PH#00 tool was too big; the PH#000 worked perfectly-- we did buy this used and it's "possible" that the screws were replaced-- but it would seem odd if all of them were-- having said that, there are 3 missing-- luckily the case seems to be holding together ok.
Piece of cake! :)
hi is it possible to upgrade RAM from 2 X 2GB to 2 X 4GB
Hi Ramón,
Yes, you can indeed upgrade the memory to a total of 8 GB. Just remember to use 2 identical RAM modules (PC3-8500).
Hi peoples
I’ve had my 2010 A1286 MBPro die and am thinking about putting the 8gb of RAM into my 2008 A1278 Macbook. Is this possible or wise? Looking into compatibility now. Its currently running 2gb in total and desperately needs a bump.
If anyone has any insight would love to hear!
Thanks in advance.
Hi Matthews
Your 2008 has a SSD?
There’s no big difference between 4Gb and 8Gb of RAM
if you have and SSD.
If you want a rocket ? change your HDD
Disculpa Una pregunta la Memoria RAM 8GB 2x4GB Corsair CMSA8GX3M2A1333C9 Mac Memory son compatibles con la MacBook de finales de 2008, con procesador Intel Core 2 Duo a 2Ghz es que ando buscando estás que si son compatibles memoria de Corsair para Mac, un kit de dos memorias CMSA8GX3 de 4gb y no las encuentro
Hola Sergio
No son compatibles en teoría.
Esa corre a 1333 y necesitas una que corra a 1066 Mhz
Yo se las cambié pensando que iba a haber una gran diferencia y no fue así, la gran diferencia está en cambiarle el HDD por uno sólido.
Hola amigos, tengo un Macbook 13” Late 2008 Processor 2 GHz Intel Core 2 Duo Memory 2 GB 1067 MHz DDR3 - con OS 10.9.5 y esta caducando ya. He estado leyendo en foros que cambiando el disco a SSD (Disco sólido interno SanDisk SSD Plus SDSSDA-240G-G26 240GB) y subiendo el RAM a 8gb (me recomiendan Memoria RAM Mac Memory 4GB 1x4GB Corsair CMSA4GX3M1A1066C7) ya podria actulizar el OS a una version bastante decente (no se si OS 10.15). Uds. que recomiendan? Vale la pena la inversion? (el gasto aca serian Us$100 en la hardware) + horas hombre (no conozco pero a punta de tutoriales.
Gracias por su tiempo
Thanks Walter Galan (and other contributors). With this guide I was able to upgrade my Unibody Macbook A1278 to 8GB RAM (2 times 4GB). Very nice!
Next job is some LVM surgery to expand my swap partition from 4GB to at least 8GB (taking the space from my /home partition) so I can still have hibernation working. I'm running Debian Linux on this machine. Not only is it liberating, but it's the only way of keeping such an old machine running up-to-date software.
I originally bought the RAM sticks from iFixit intending to upgrade my old Lenovo Thinkpad X20 from 4GB RAM to 8GB. But that didn't work. Not having time to diagnose the problem, I found a home for the RAM by using it to upgrade this Macbook.
Correction: That was a Thinkpad X200.
This is not a a1278 unibody MacBook Pro. A1278 MacBooks backs are one solid metal piece not two separate pieces. This guide is for a different MacBook Pro.

This guide isn’t for a pro; it’s a MacBook unibody.

So, it turns out that Apple used the model code A1278 for quite a few different Mac models, including both Pro and non-Pro versions! This guide is for the non-Pro Macbooks. There’s also one for the Pro models with the same A1278 identifier.
