Reviewer: Suhr Owned Product: over 6 months
Rating: 5/5 Mac Pro 2009 runs macOS Sierra December 15, 2016 macOS Sierra WILL run on a 2009 Mac Pro, HOWEVER…

You cannot download macOS Sierra with a 2009 Mac Pro. You cannot install macOS Sierra with a 2009 Mac Pro.

STRONGLY SUGGEST YOU TRY THIS ON A FULLY FUNCTIONAL CLONE OF YOUR BOOT DRIVE!!!! This message references the 2009 Nehalem Mac Pro. The solution is to remove your 2009 Boot Drive and put it in a 2010-12 Mac Pro and install macOS Sierra. (obviously macOS Sierra must be downloaded with a compatible Mac) Once completed, put the boot drive back in your 2009 Mac Pro. I put the 2009 boot drive in a 2010 Mac Pro. I made a copy of the macOS Sierra installer and made a ZIP. I copied this to the 2009 boot drive Applications folder. I unzipped the installer, deleted the zip and ran the installer on the 2010 MP. Once finished I shut down and put the boot drive back in the 2009 MP and voila!

At the moment, I have tested boot compatibility and numerous applications and have Not discovered any problems. I even tried Mail, Safari, App Store, Adobe CS6, etc.

I cannot confirm “100%” compatibility at this time but so far all runs just fine.

I would recommend this item to a friend! Customer Videos:

Rating: 5/5 Great value for the money September 20, 2015 Although the condition of this Mac Pro was advertised asUsed/Good I found it to be in excellent condition & functioning great as of this review.

I did need a little help in accessing the DVD drive & got courteous & helpful advise. It was a simple bit of computer ignorance on my part but the tech that helped me didn't make me feel like a complete idiot.

Great free shipping with excellently packaging.

I'll certainly look to OWC for future computer needs.

I would recommend this item to a friend!
