Replace the RAM in your MacBook Pro 13" Unibody Mid 2010.

Originally, the maximum possible RAM configuration was 8 GB. However, systems running OS X 10.7.5 (or higher), updated with the latest EFI, and equipped with proper specification memory modules can support up to 16 GB of RAM. —Source

    • Remove the following 10 screws securing the lower case to the MacBook Pro 13" Unibody:

    • Seven 3 mm Phillips screws.

    • Three 13.5 mm Phillips screws.

    Compare the short screws carefully before reinstalling them. The shouldered screws go in the holes on the front edge.

    Before I started removing any screws I took a piece of paper and drew the bottom of the laptop and put a piece of double-sided tape in the spot where each screw goes. That way when I took out the screws, I could put them on the tape so I knew exactly which screw went in which spot. I did the same thing for dismantling the inside on another sheet of paper, then a third sheet for the screen after getting the front glass off.

    I use a similar technique: I print out the iFixit manual for the job, and Scotch-tape down the screws/brackets/cables I remove at each step next to the component descriptions. That way, when I'm reassembling, the bits are taped right next to the photo of where they came from.

    That's exactly what I do for all my repairs! It's the best way to keep track of all of the parts ' original location and to make sure that you don't miss any parts during reassembly.

    Great idea and one I use often

    Thomas Overstreet -

    Excellent idea! Thanks for sharing it here.

    I used a 00 that fit but the screws were very tight so I used a tiny paintbrush with some wd40 on it and put it around the edges of the screws. Worked like a charm

    • Slightly lift the lower case and push it toward the rear of the computer to free the mounting tabs.

    In the introduction you should link fixers to this excellent doc: https://www.ifixit.com/Misc/HD_Software_...

    It is really critical, super easy, and free(!) to clone your existing drive onto the new one you will install. I ran into one error, but SuperDuper! support replied immediately on how to fix it...Thanks ifixit and SuperDuper! (I ponied up the $28 for the software anyway, I was so impressed!)

    why is step 3 necessary?

    Just to disconnect any power source to avoid damages by short-circuits.

    MrKane - 답글

    How do you get that battery connector back on? Do you just press it in back in place after you're done?

    Horace Chung - 답글

    yes. I usually plug it in before I screw it down so I can lift the battery a bit and have enough slack to be able to go straight down on the connector, otherwise it comes in on a bit of an angle, which can't be good (though not necessarily bad).

    This step almost finished me, and I did extensive damage to the battery plug. Fortunately, I later replaced the battery, and the replacement came with a new plug! :) Newbies need to know - 1. The battery plug is like a thin lip on a thicker lip, so you need to pry BETWEEN 2 thin lips to get it off, else you are trying to yank out the socket. 2. Mine was initially VERY tight, and trying to get it out broke the plastic on all sides of plug, even though I was as careful as possible. Luckily, this didn't hurt functionality and I later replaced the battery. AFTER disconnecting once, it was never so tight again,

  5. 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.

  6. 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.

    Do this step slowly! Depending on the age of the components, both ram and the system board, removing and inserting RAM can actually break threads on the board that read and write info to the ram sticks. It should be very easy to remove the ram. If it seems hard to remove, stop and make sure you have followed all the steps correctly!

Hey, I put 16Gb RAM in my MacBook Pro Mid 2010. I bought in another store because iFixit doesn't have.

Thanks Walter Galan to more this tutorial!!

Please answer this question. Today i purchase Macbook Pro core2duo model: A1278 year: 2010 Laptop and i found the ram is 2gb DDR3 1333mhz bus speed.

So will 1333mhz bus speed support my macbook or it will crash randomly ? or i should buy another ram of 1066mhz bus speed.


Muhammad Talha - 답글

The front side buss speed is 1066mhz so that the speed the board talks to everything including memory, it can't talk any faster so putting 1333mhz will run at 1066mhz. So I would go with 1066mhz and save your money. If you also make sure you firmware for the board is up-to-date and you are running latest OS it can take you should've able to run 16GB ram, even if apple say it only supports 8GB. If you get the correct ram you can run 16GB that's what I have in mine running high Sierra. In have same system as you. You may also want to think about adding a solid state drive in place of the drive that's in with will probably be a mechanical drive. Believe me you will seen the difference in speed when the system starts up etc.

My macbook has somewhat of a week bottom ram stick holders. The stick pops right out when being mounted into it’s slot.

Is this a known problem? is there a good mechanical solution for this other than taping the ram stick down? maybe bending in the holders or something?

Hallo Walter,

ich habe das gleiche Model und habe mir vor 1,5 Jahren eine 256 SSD Platte und 2x 8 GB 1066 GHz RAM Erweiterung einbauen lassen.Leider hatte ich dann immer Abstürze bzw “Kernel panics”. Bis wir einfach die neuen RAM´s raus und die alten 2x2 GB Ram wieder eingesetzt haben und siehe da, seit dem läuft das MBP ohne Murren.

Nur ist die Performance bißchen dürftig und auf el Capitan geht auch alles gut. Aber ich möchte gerne auf Sierra umstellen und deshalb würde ich gerne wissen, ob eine Erweiterung auf 16 GB tatsächlich geht und ob es an der Marke der RAM liegen kann? Mit welchen 2x8 GB hast Du gute Erfahrung gemacht oder soll ich sicherheitshalber doch nur auf 2x4 GB gehen?

Herzlichen Dank für Deinen Rat.

Translation of furby_luzzie’s comment:

Hello Walter,

I have the same model and 1.5 years ago I installed a 256 SSD disk and 2x 8 GB 1066 GHz RAM extension. Unfortunately I always had crashes or "kernel panics". Until we just put out the new RAM's and used the old 2x2 GB Ram again and lo and behold, since then the MBP is running without a grunt.

Only the performance is a bit poor and everything goes well on El Capitan. But I would like to switch to Sierra and therefore I would like to know if an extension to 16 GB is actually possible and if it can be due to the brand of RAM? With which 2x8 GB did you have good experience or should I just go to 2x4 GB for safety?

Thank you for your advice.

ted - 답글

Be careful ! according to different other customers experience (read ifixit forum) and my own, it might be a hit or a miss.

I tried the upgrade to 16gb, no matter where or which one of the 8gb ram module is place, the Mac doesn’t want to recognize more than one module at a time, so I ended with 8+2=10gb , which is still an upgrade but deceiving money wise.

Sebastien CHAPUIS - 답글

Which MHz speed do your 8 GB modules have? If both are faster then 1333 then the Mac will not startup. I can combine a original 2 GB 1066MHz module with a 8GB 1600MHz to 10GB then the older module decides the speed and it works. But if both are the 1600MHz then the bios will not boot and I get an error signal. Will see if it could be cheaper to just get one 8GB module with 1066 or 1333 that forces the 1600 to work at lower speed.

Hi Sebastien,

My machine had similar symptoms. See my comment below. GL!

I also had an issue upgrading to 16gb. I purchased two 1066MHz 8GB RAM cards from ifixit, and when both are installed the MacBook won’t boot. It’s a 2.4GHz Core 2 Duo, the only specification for this change I haven’t been able to confirm is the EFI version, but I’m assuming with High Sierra it’s probably up to date (Boot ROM Version:, SMC Version: 1.62f7). Tried to run an update to 2.5, but that fails (again assuming it’s because it’s already up to date).

My final solution was the same as above, a combination of an 8GB and a 2GB card.

Has anyone found an answer to this? Has anyone yet tried an 8GB and 4GB combination?

Today I did my first repairs on my MacBook Pro 2010. I replaced feet, battery and upgraded both RAM chips from 2GB each to 8GB each. The only issue was that it wouldn’t turn on. :( After a little bit of panic and self doubt as to why I would ever consider doing this, I back tracked a bit. I uninstalled both Rams and put my old back in. My computer worked fine. Then I just tried each new and old, in combination, to find the culprit. Turns out that one of the new chips must be defective.

I am a happy girl! I sincerely thank you all for posting your videos ,comments and especially your mistakes. They give me courage and inspiration to forge ahead on this wonderful road of repair! Thank you iFixit and Right to Repair!

I recently purchased the 16gb upgrade, followed the instructions for installation, but my MacBook Pro will only work with one 8gb stick and the original 2gb stick it came with. It doesn’t matter which slot I put them in. I have a mid 2010 MacBook Pro, with 2.4GHz Intel Core 2 Duo, running High Sierra 10.13.6. Any ideas why it won’t accept the second stick of memory?

Loved doing this part of my mid-2010 MBP 13-inch upgrade - moving from a total of 4gb (original install) to 16gb (2x8gb) - running High Sierra 10.13.6 . Very doable with, again, great concise, yet enough detailed write-ups and clear/to-the-point pics. Thank you.

I had a similar issue others have described wherein the machine (MacBook Pro 13" Unibody Mid 2010) would recognize either of the new IFixIt sticks in either position when paired with either of the OEM sticks (8 permutations tested, LOL), but not both new sticks paired together. OSX, SMC, EFI and associated firmware appeared up-to-date. Purchased a different set of 2x8GB sticks from a competitor and they worked like a charm. Noticeable performance increase from factory 4GB and from 10GB hybrid. To their credit, IFixIt accepted my return without question despite being well past their standard 30-day policy. Very happy with them, and will continue to give them my business.

FWIW, new (working) RAM appears identical, spec-wise: 2x8GB PC3-8500 1066MHz. Timings are printed 7-7-7-20. Couldn’t find timing noted on IFixIt RAM. I wouldn’t think a difference would matter… maybe the IFixIt memory wasn’t compatible with the controller in some way. Anyway, a potential solution to try.

I bought 2 8gb ddr3 pc3-8500 1066mhz 204 pin ram sticks. My mac is the mid 2010 core duo version with updated 10.13 os highsierra so i would expect the ram to load and the mac to boot, but it didn't. It beeped 3 times. I reset the pram and reloaded the original ram and it works like it did. I'm wondering if something is wrong with the new ram or if it might be necessary to reset the scm(?) too? There seems to be small differences in the new ram versus the old aswell, worthy of note.
