Certain ’10 MacBook, MBP, Mac minis Join 16GB MaxRAM Club

Do you have a 2010 Mac mini, 13” MacBook or 13” MacBook Pro? Can you benefit from more than 8GB of memory? If you answered yes to both, you will be pleased to know that extensive qualification in our test lab has concluded. These Macs are now OWC MaxRAM Certified for up to 16GB with this OWC 16GB Memory Kit available now and specifically qualified just for these Mac models.

While these systems were originally factory limited to 8GB, the right Apple OS version, current EFI update(s), and correct spec/build memory modules now enable them to support and have the full benefit from up to 16GB of installed memory.  This isn’t the first time something like this happened, however, after the fact enabling such a benefit. A while back, we had a similar instance with the Late 2008 MacBook Pros, wherein having the proper OS version and a particular firmware update allowed you to max your RAM out at 8GB vs. a prior 4GB to 6GB max.

Just like with those Late 2008 MBP models, your Mac needs to meet specific criteria for this to work. In the case of the 2010 Macs, here’s what you must have:

  • a Mac mini (Mid-2010), a MacBook (Mid-2010) or a 13” MacBook Pro (Mid-2010)
  • Mac OS X 10.7.5 or later
  • the latest EFI firmware update for your system
  • the proper specification memory modules

As there is the possibility of confusion here, let’s elaborate on those requirements.

A Mac mini, MacBook, or 13” MacBook Pro from 2010

At this time, 16GB MAXRam Certified Support is being Expanded to now include specifically these three 2010 models:

  • Mac mini (Mid 2010)/Mac mini Server (Mid 2010) – Model ID: Macmini4,1
  • MacBook (Mid 2010) – ModelID: MacBook7,1
  • 13” MacBook Pro (Mid 2010) – ModelID: MacBookPro7,1

If you are unsure of which model you have, these instructions will show you how to quickly find out. If your Model ID matches one of those listed above, it is among those now newly supported for the 16GB Max. Using our complete online memory guide, you may also review and quickly determine the available memory options for nearly any Mac model.

OS X 10.7.5 or later

The OS plays a part in how memory is supported and in this case OS 10.7.5 ‘Lion’ or later (including 10.8.x ‘Mountain Lion) is a requirement for upgrading beyond the original 8GB factory maximum.

Latest EFI Update for your machine

Occasionally, Apple will release an update to a machine’s EFI firmware to resolve hardware-level issues. These are Apple recommended updates which include documented additions and/or improvements for your Mac that also have the occasional undocumented benefit as well. As some EFI updates are required for OS Version or application compatibility, we recommend keeping these up to date regardless of whether or not you intend to upgrade to 16GB. These updates come down via Apple Software Update just like other OS updates.

In most cases, if no EFI updater shows up in Software Update, you’ve probably got the latest version already installed. If you want to be extra sure, you can always check Apple’s listing of latest EFI updates to see if yours matches.

The proper modules

Finally, no different than any size upgrade for your Mac, you need to get the right spec memory for your model. Our OWC MaxRAM certified memory upgrades are available in both single 8GB modules and in 16GB matched pairs that are guaranteed correct for the job and lifetime warranty backed.

More memory can really make the difference enabling applications to operate more efficiently and to better utilize the processing horsepower your Mac has always had. Upgrading memory also happens to be one of the easiest and best bang for the buck upgrades you can do today too. It’s a great option to have and great to see up to 16GB support expand to now include these additional Mac models.

A special call out to Paolo D. for his feedback and reporting that put the spotlight back on these Mac models – Thank you!

  • Hi,

    I’m planning to upgrade my wife’s Macbook Pro 13inch Mid2010 (2.4 Ghz Intel Core 2 Duo) by purchasing below parts from your website:

    16.0GB (2x 8GB) PC3-8500 DDR3 kit for 27″ iMac 2009, Mac mini 2010, MacBook 2010, & MacBook Pro 13″ 2010
    OWC SKU: OWC8566DDR3S16P

    500GB Mercury Electra 3G 2.5-inch 7mm SATA 3.0Gb/s Solid-State Drive
    OWC SKU: OWCS3D7E3G500

    OWC Data Doubler Optical Bay Hard Drive/SSD Mounting Solution for select Apple Laptop Models

    I’m Linux/PC guy so I don’t know much about OS/X and MACs in general. From what I read on your website in order to upgrade 16G ram we need to install certain OSX and upgrade to latest EFI. Our Hardware specs and OS version as below:

    Model Identifier: MacBookPro7,1
    Boot ROM Version: MBP71.003D.B00
    SMC Version (system): 1.62f7

    When I checked Apple Support website for BIOS/EFI version:
    MacBook Pro (13-inch, Mid 2010) MacBookPro7,1
    MBP71.0039.B0E (EFI 2.5)
    1.62f7 (SMC 1.6)

    I tried Software Update but it didn’t say I need EFI version upgrade. If I purchase above parts from your website, is it OK to upgrade without EFI update (with my current EFI MBP71.003D.B00 and SMC Version:1.62f7) ?


  • Hola que tal tengo una macbook pro 15 pulgadas
    Version 10.10.5
    4 gb ram 1067 DDR3
    Le puedo poner
    8 gb ram 1600 DDR3

  • I’ve started having crashes when 16gb is installed in my 2010 mbp. It has run fine with 16gb for 3 years but now won’t. I have tried new memory as well as testing all four 8gb DIMMS and getting no failures. Is it possible some software or firmware has reverted these machines back to max 8gb? Any tips?

  • can i combine a pc3 and pc3l rams of 8 gb each to make 16gb total in a macbook pro 13″ mid 2012 2.5ghz? currently using 10gb ram (8gb+2gb).

  • Hi, I have a mid-2010 Mac Mini (Macmini4,1) 2.4 GHz Intel Core 2 Duo Boot ROM Version: running OS High Sierra. I bought the 16gb kit from you guys but when I installed it my Mac thinks there is just one gb stick of ram in there and that the second (the higher slot) is empty. I previously had two sticks of gb of ram, one in each slot, totaling 8GB so I know the slots are not bad. After reading all over this website my model should work (at least I think I am understanding the requirements right), so what am I doing wrong here? Thanks!

  • Hi.

  • Same I have a MBP 5,5 mid 2009
    AND has anyone TRIED 16Go Ram on it ?
    I’m not after the answer “your max is 8” I can find that everywhere but does it actually work ?
    I’m not after someone else answer found somewhere

  • Add me to the list of people who couldn’t get 16GB to work on a Mac Mini 4,1 Server. I had the same symptoms as some others here: only the OEM 2GB module would work in the lower slot. I had upgraded the EFI, reset the PRAM and SMC, and ran the hardware diagnostic tests with no errors reported.

    So be aware that 16GB may not work on at least some Mac Mini 4,1 (Mid-2010) servers.

  • I saw no comments on my last post. Called for an RMA and followed the suggestions from OWC customer service, exhausting all possibilities that might prevent the 16 Gb of memory from working. The RMA arrangements went very smoothly as I was guided through the process. A cross ship sales order was set up on Tuesday and my replacement memory arrived on Friday with their receipt of the defective memory being the same day. Installed it and successfully booted into 16 Gb on the Mac Mini with no problems. I am very impressed by the support I received and will continue doing business with OWC. I will recommend this well organized company to Mac user friends and family.

  • I just received 16 Gb ram upgrade from OWC. This is for my Mac Mini Server 4,1 mid 2010. I am running Mac OS X 10.11.
    According to what I read on your site, the hardware and OS should allow access to 16 Gb. Upon boot up the Mini will not go past a regular beep accompanied by the flashing indicator. Did I miss something in researching this upgrade? Before I request an RMA, I would appreciate some help. Thanks.

  • Hi, your website says that mid2010 MBP can be upgraded to 16gb (2x8gb). Could you please tell me if it work to my MBP 13″ mid2010 2.4gHz Core2 duo, 7,1 running macOS Sierra ver10.12.4.

    I’m planning to purchase OWC ram 16gb upgrade to my MBP.


  • Hi, I have a 13″ mid 2010 macbook pro 7,1.
    I would like to upgrade to 16GB ram (2x8gb).
    Do you know if DDR3-1600 will work? or do they need to be 1066mhz?

  • Hi! I’m using a macbook pro 13″ mid 2012 (yosimite) Can I safely upgrade to 16gb ram? And can you suggest ram specifications that would fit the MBP best? Thanks!

  • Hello, I have an MacBook Pro “Core 2 Duo” 2.4 13″ Mid-2010Model, A1278 (EMC 2351*) , came stock with 4GB (2x2GB). I would know if I can upgrade it up to 16GB instead of 8GB RAM max? I just looked on your blog and there are people saying that will not work. Can you explain me in details , please? I would buy some RAM Modules. Also do you offer shipping to Ireland or Romania? Thanks in advance!

  • I just received my upgrade pair of 8GB ram for my Mid 2010 MBP7,1. I’m running OSX 10.10.5 and just installed the most recent updates but my Boot ROM Version still shows MBP71.0039.B0B (not MBP71.0039.B0E). Will this present a problem?
    SMC Version (system) is 1.62f7

      • Thanks Dyllon,

        I previously looked at the download page and hesitated because the sys requirements specifically call for Mac OS X 10.7.2. I have OS X 10.10.5 (Yosemite). It doesn’t state “10.7.2 or LATER versions”.

        Will I have to downgrade my OS to install the EFI Firmware update 2.5? Or can I proceed with Yosemite?

        Thanks again!

          • I’m in the same case but with Captain 10.11.6, but have a concern: “MacBook Pro (13-inch, Mid 2010) EFI Firmware Update 2.5” web page also states “This update enables Lion Recovery from an Internet connection on MacBook Pro (13-inch, Mid 2010) models.”.

            What this mean?. If I download and run the Firmware Update 2.5, will Lion version replace my Captain version?.

            In your answer for Yosemite version you stated that it would run ok. Is the same for Captain version?. Is there any need to donwgrade the OS to Lion version?.

            The “EFI Firmware Update 2.5” web page also talks about using Lion Recovery and refers to “http://www.apple.com/macosx/recovery/” which refers to recovering from Time Machine.

            Well, I need to be sure before updating the firmware so I’d appreciate some guidance from you.


  • I have a mid-2009 MBP that I’m trying to determine whether or not can be updated from its current 8 gigs of DDR3 ram to 16 gigs of DDR3L ram. Throughout my research I still have not seen clearly why I cannot update my ram. The information on the net is also all over the place with equal parts saying you can/cannot, but no clear explanation as to why/why not.
    Lastly, if I update my HD drive to an SSD does this mean I could then update to 16 gigs? Thanks for reading through this. Much appreciation!

    • Hello Tyson,

      Great questions! Upgrading your computer to an SSD will not have any affect on if you can put 16GBs of RAM in your computer. This will however allow your computer to have much greater performance!

      In order to determine how much RAM your computer can support, please contact our Technical Support Team! We will be happy to help you!

  • I have a mid 2010 13 inch macbook white unibody and I just upgraded from 2x2gb to 2x8gb. The problem is that I can’t get my computer to boot with both 8gb cards. They each work with a 2gb card (and my computer registers that it has 10gb ram), but they won’t work together.

  • Hi, i have a MBP15″ mid 2010 :
    2,4 GHz intel core i5
    4 go 1067 MHz DDR3

    I want to change my disk for a Samsung Ssd 1 To and I was wondering about the RAM, do you think i can put 2 x 8 go or only 2 x 4 Go

    Thx for help me : )

  • I have a mid-2011 mac mini (core i5, intel graphics)… matched up a 2×8 16GB kit for it and it will not work. I have OSx 10.11… tried to install the efi update and it says it requires 10.9.5 to install… I am wondering if the new efi that may have installed with 10.11 won’t yet work with 16GB?

  • Hello there, is the mid 2009 17inch macbook pro still maxed out at 8gb or ram? Do you think there may be an update that will allow more RAM? Thank you.

    • Hi, your MacBook Pro model is compatible with up to 8GB of RAM. We can’t speak to any future updates or changes.

    • FWIW, I have been using my 17″ MacBookPro8,3 with 2x8GB DDR3 1333MHz (16GB total) for 5 years now. It truly pains me to use my other MBP’s with 8Gb or less ram. I stuck with OSX10.6.8 until a year ago and now I’m with 10.8.5 (avoiding 10.9-10.10).
