Chosen Solution

PC3-8500 DDR3 Min. RAM Speed: 1066 MHz

Standard RAM: 2 GB Maximum RAM: 8 GB*

Details: 2 GB of RAM is installed as two 1 GB modules, no slots free.

*Apple officially supports a maximum of 4 GB of RAM. Originally, this model was only unofficially capable of stably supporting 6 GB of RAM, but as confirmed by OWC, it is capable of supporting 8 GB of RAM if updated to Boot ROM Version MB51.007D.B03 and running MacOS X 10.6 "Snow Leopard" or higher.

What / who is OWC? Is it official? And how do I update to Boot ROM v MB51.07D.B0 or check what I have? I run on El Capitan and plan to upgrade to High Sierra if added RAM is possible.


These Mac models are compatible with macOS Sierra:

MacBook (Late 2009 or newer)

MacBook Pro (Mid 2010 or newer)

MacBook Air (Late 2010 or newer)

Mac mini (Mid 2010 or newer)

iMac (Late 2009 or newer)

Mac Pro (Mid 2010 or newer)

OWC Other World Computing



Thank you!! Perhaps overextending the original question, I understand it is compatible, but will High Sierra improve a MacBook (plain) Late-2008 aluminium unibody 2,0 GHz performance or worsen it? (I read extensively that e.g. Leopard was heavier than Lion/ML for older hardware, the same for SL vs. L)


@freddycrux I don't think you do understand. Your machine IS NOT compatible with Sierra or High Sierra.


Sorry and thanks for clarifying. I got things totally mixed up..... I was at the same time thinking if my other MB Air 2012 (5,2 1.8 GHz, 4 GB RAM, 256 HDD), would actually benefit or worsen from an upgrade from El Capitan to HS..... And surely a new post is the best way to go about it, but since you've been so kind to respond in detail and quickly, I'll just A2A this way.
