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.

    • 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.

    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.

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

    • 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.

    • 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.

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 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.

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!

Melvin - Ответить

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

Sesan Munusamy - Ответить

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


ramonol - Ответить

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).
