Accessing the RAM in this computer is straightforward and requires minimal disassembly.

  1. With the case closed, place the Unibody top-side down on a flat surface.
    • With the case closed, place the Unibody top-side down on a flat surface.

    • Depress the grooved side of the access door release latch enough to grab the free end. Lift the release latch until it is vertical.

    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.

    • Grab the white plastic tab and pull the battery up and out of the Unibody.

    Great tutorial ! great step !

    Even though it’s specifically stated, you have to make sure the access door latch is vertical or the battery won’t be removable.

  4. Remove the following eight screws securing the lower case to the chassis:
    • Remove the following eight screws securing the lower case to the chassis:

    • One 3 mm Phillips screw.

    • Three 13.5 mm Phillips screws.

    • Four 3.5 mm Phillips screws.

    On my model, it seemed the top-left was 3.5mm and the bottom 4 were 3 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.

    Nickolas Michelinakis - 답글

    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.

    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.

  5. Using both hands, lift and remove the lower case off the upper case.
    • Using both hands, lift and remove the lower case off the upper case.

  6. Release the tabs on each side of the chip by simultaneously pushing each tab away from the RAM.
    • Release the tabs on each side of the chip by simultaneously pushing each tab away from the RAM.

    • These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

  7. After the RAM chip has popped up, pull it straight out of its socket.
    • After the RAM chip has popped up, pull it straight out of its socket.

    • Repeat this process if a second RAM chip is installed.

    So happy :D Why to go elsewhere ?

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.

mrstiffanyjudson - 답글

I just upgraded to 2 4GB chips. Works fine sofar!

Sten Folkerman - 답글

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.

Jonathan -

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?

dunkelcreature - 답글

Sounds like bad RAM. I would contact who you purchased it from. If it was us, email support [at] ifixit [dot] com

Scott Dingle -

I noticed the back of the Macbook Pro in the picture looks different than mine but I have an A1278 too. What year is the one in the display and would I follow these same directions to replace RAM on a mid-2010 Unibody Macbook Pro.

Sharizzel - 답글

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.

I replaced my 2x 1GB ram by 2x 2GB out of my Mac Book Pro. Works fine with the faster DDR3 RAM 1333 Mhz PC3-10600 so far!

Hi, which model of the macbook? I tried but did not succeed!

Can i upgrade it to 16gb in yosemite?

Melvin - 답글

hi is it possible to upgrade RAM from 2 X 2GB to 2 X 4GB

Sesan Munusamy - 답글

I need know too if it’s possible upgrade to 2x4gb (8gb total memory), has anyone prove it?. Thanks.

Ramón

ramonol - 답글

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.

Matthews - 답글

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

Sergio Rojas - 답글

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
