High I've been running macOS Sierra on MacPro 3,1 with pc version of AMD R9 280X with flashed EFI (no black screen prior to boot) for last year and everything worked fine. I have tried to do the clean install of High Sierra 10.13.5 recently applying dosdude patch, including AMD card patch (it...

I have two GPUs for my early 2008 mac pro (2x 3.2ghz Xeon, 16GB OWC Ram), the first is an EVGA GTX 285 flashed with the mac efi and the second is an Apple radeon 5770. The system runs OS X 10.11.6 just fine. The strange thing is that in most games on OS X the 5770 outperforms the 285 by a...

I did a search but could not find any info so here it goes my question: I have a Mac Pro 3,1 that I just did a clean install of El Capitan latest version while I waited for a new Mac Pro 5,1 to arrive. No I got the new one and I am not looking forward to installing everything from scratch...

I find it interesting that Apple does not support macOS Sierra on our old Mac Pro 3,1 and yet the virtual machines running El Capitan inside of it in Parallels can be upgraded to Sierra seemingly with no problem. Seems not too intuitive the lack of support.

Hey Guys, i might be able to buy a Mac Pro 3.1 with 2 X Quad Core CPU 2,8 Ghz and the AMD 2600 XT. Do you Guys think that this is still worth buying. And it is a worthy investment to buy a 500GB SSD, a Radeon R9 280X and PCIe USB 3.0 Board? Please let me know if you can give me a...
