Hey all,
So, I'm running a 2010 Mac Pro (8-core, 42 GB RAM, OS X 10.9.5) with a Radeon Sapphire 7950 graphics card. Curious if anyone has encountered any issues with Yosemite on a configuration like this, particularly with the 7950. No reason to think the graphics chip would stop working, but worth a call-out!
Thanks.

Mac Pro, Mac OS X (10.6.8), 8-core Westmere (2x2.4GHz)
ok thanks for the info. I have one 500w external supply but not sure that will cut it. Any ideas? This is my first time having to do this. Fun!
The purpose-built supplies the shape of a DVD reader, intended for internal installation, are 450 Watts
Anybody know if you NEED the 'mac' version... I'm trying to get this card on eBay and there seem to be a multitude of 3G Sapphire Radeon HD 7950's, and model numbers... Any thoughts to what is the right or wrong model number to be compatible? Don't want to have to do this more than once.
The big issue is always the power.
The slot itself supplies 75W
Each of up to two six-pin aux cables supplies 75W
An 8-pin aux cable requires 150W, and although it is all 12Volts and returns, you can not just splice 6 from the Mac onto 8 for the card and expect that to work.
a side issue is if not running 10.8.3 or later, you may need genuine Mac firmware, and if not running genuine Mac firmware, you may not get Boot-up screens.
There has only been one Mac specific version of the Radeon HD 7950 and it was made by Sapphire. It can be recognised by having a white plastic cover on the card, normal PC versions typically have a red plastic cover.
It is possible to 'flash' a PC version with Mac EFI compatible firmware but if you want the 'official' Mac version look for one with a white plastic cover like this one. http://www.sapphiretech.com/productdetial.asp?pid=4602E84F-4A09-4B9A-B9F9-CBA9CF 197B15&lang=eng
It is of course now discontinued but I bought one via eBay previously myself.
As mentioned you can flash PC equivalent models, this is done using a Windows utility typically by running Windows in Boot Camp, you cannot do it when running Windows in a virtual machine. Ideally you want to find one that looks as similar to the Mac one in appearance as possible, particularly with regards to the video connectors. The Mac one has two Mini Displayport, one DVI, and one HDMI connector. As you will see from above the Mac one also has a single fan.
