    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.

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

  5. 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 - Yanıt

    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.

    Bill Cole - Yanıt

    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.

  7. 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.

  8. 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.

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 - Yanıt

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

Sten Folkerman - Yanıt

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 - Yanıt

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 - Yanıt

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! :)

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!

oxolong - Yanıt

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

newageemo -

Can i upgrade it to 16gb in yosemite?

Melvin - Yanıt

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

Sesan Munusamy - Yanıt

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

Ramón

ramonol - Yanıt

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).

Kim Vexborg - Yanıt

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.
