Hello! First post in the forums. Has anyone had any luck with this card in general? The computer kernel panics every time. Non of the nvidia web drivers will install on my computer, so I'd assume that I have the latest one for my OS (10.11.6). I've tried installing it in both of the PCIE x16 slots and no dice. Is this card a simple no go or am I missing a part of the puzzle? The card is a GT 730 MSi OCd 2GB GDDR5 PCIE 2.0 Heres's my run down: Model Name: Mac Pro Model Identifier: MacPro3,1 Processor Name: Quad-Core Intel Xeon Processor Speed: 2.8 GHz Number of Processors: 2 Total Number of Cores: 8 L2 Cache (per Processor): 12 MB Memory: 20 GB Bus Speed: 1.6 GHz Boot ROM Version: MP31.006C.B05 SMC Version (system): 1.25f4 Any help would be greatly appreciated! I have only so many days with the card before I lose a full refund. Thank you!
