*While researched thoroughly via independent resources, OWC does not make any claim to accuracy or completeness of these specifications.
To say that I was tentative about it was an understatement, as while I wanted one of these badly, the description of condition is a subjective thing. Now do understand that my current 3,1 was savaged by FedEx when it was shipped to me - so badly, the top handles were nearly smashed flat! Needless to say, they paid me for the damage but I still put the machine to to work, and work it has for several years.
OWC described these Mac Pros as "Fair", so I was expecting the worst.
Imagine my surprise when my new (to me) Mac Pro 4,1 arrived and I opened the box, only to see nothing discernible in the way of damage or disfiguration of the case. Wow! But - when I saw the other side of the case, there was a wide scratch on the case above the service door. Meh. It wasn't a big deal.
Going over it with a fine toothed comb yielded nothing else in the way of wear and tear. While this was only the machine I got, if this is OWC's idea of "fair", they are being very, very conservative.
I've purchased from OWC for many years, and always been pleased with the service and quality of their offerings. This just confirms that my continued experience with OWC is right on target, and they can count me in as a customer for many years to come.
Thanks, OWC!I would recommend this item to a friend! This review is from Apple Mac Pro (2009) 3.33GHz 4-core Xeon W5590 - Used, Fair condition.
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! This review is from Apple Mac Pro (2009) 2.66GHz 4-core Xeon W3520 - Used, Good condition.
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! This review is from Apple Mac Pro (2009) 2.66GHz 4-core Xeon W3520 - Used, Good condition.
