Jan 26, 2015 Dear Paul S, John B here. I have a 2008 Mac Pro, single Quad Core-not state of the art at all. I bought my sapphire radeon HD 7950 to replace an nVidia 8800, so that I could play Bio shock infinite on Steam. Yes, I installed it myself, it's a piece of cake. I had no issues after installing. Buy AMD Radeon R9 280X 3GB HDMI PCI Express Video Graphics Card for Apple Mac Pro, outperforms ATI Sapphire Radeon HD 2600, 4870, 5770, 7950, 9000, 9800 Gigabyte: Graphics Cards - Amazon.com FREE DELIVERY possible on eligible purchases. Oct 22, 2018 I have a Mid-2010 Mac Pro 3.33 GHz with 24 GB of RAM in it and a white Sapphire Radeon 7950 Mac Edition card. I don't use Photoshop very often but 24 GB is more than adequate for my tasks. If you have 32 GB (or more) it would be even better. About this item Make sure this fits by entering your model number. Supports Dual Firmware: Via Firmware switch controller, Sapphire HD 7950 MAC Edition supports Mac OS X/Windows under. 800 MHz core speed 5000 MHz Effective memory speed 384-bit GDDR5 memory interface Open.
I thought this switch only had two choices 1 or 2 and no middle. Is the plastic cover of this video card white or red in colour?

If it is white it is a genuine Mac edition card, if it is red it was at least originally a PC edition. A PC edition card can be converted to have Mac firmware installed - like the white Mac edition card. Typically position 1 would contain one copy of firmware and position 2 a different copy. People upgrading it to have Mac firmware would do one copy and this then means the switch can be used to switch between the Mac and PC firmware.
I would try position 1 first and if the Apple logo shows during boot-up it is using Mac firmware, if it stays black until the login screen appears then that position at least has no Mac firmware. Then try the other position if necessary. It is not compulsory to install Mac firmware on this card as I mentioned without Mac firmware if you wait till the login screen it will work, it is merely that without Mac firmware you cannot see anything until the Mac has finished booting and therefore cannot access the Recovery HD partition or use FileVault or use the Option Key to select an alternate boot drive. (You can still use System Preferences and Startup Disk.)
