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. 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. These models do not run versions of OS X prior to OS X 10.7 "Lion.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. They officially support 8 GB of RAM, but OWC has determined that they actually support 16 GB of RAM regardless of the operating system installed, although only the "Early 2011" MacBook Pro models are capable of running a version of Mac OS X 10.6 "Snow Leopard."įinally, the "Mid-2012" non-Retina Display MacBook Pro models use faster still 1600 MHz PC3-12800 DDR3 SO-DIMMs and likewise officially support 8 GB of RAM, but actually can support as much as 16 GB of RAM. The "Early 2011" and "Late 2011" MacBook Pro models use faster 1333 MHz PC3-10600 DDR3 SO-DIMMs. If running a version of Mac OS X 10.6 "Snow Leopard," these models only can use 8 GB of RAM.

Specifically, as discovered by OWC, the 13-Inch "Mid-2010" MacBook Pro models (and only the 13-Inch models) - the MacBook Pro "Core 2 Duo" 2.4 13" Mid-2010 and "Core 2 Duo" 2.66 13" Mid-2010 identified by MacBookPro7,1 - can support up to 16 GB of RAM with dual 8 GB memory modules if they are running OS X 10.7.5 or higher, have been updated to use the latest EFI, and are equipped with proper specification memory modules. The "Mid-2009" and "Mid-2010" MacBook Pro models support 1066 MHz PC3-8500 DDR3 SO-DIMMs and officially and unofficially support a maximum of 8 GB of RAM with one odd exception. The 8Gb limit seems to be an Apple supported limit, but many people happily report getting 16Gb working fine - see the memory section in the link as well as this page for details.
