I can also now confirm that with the latest dosdude1 Mojave Patcher Version 0.1b4 and Mojave Beta 10.14 Build 18A326g, I am successfully running on my 2 x 3.2GHz Mac Pro 3,1.
Prior to this latest release I was having all of the same issues other 3,1'rs had, like the long boot screen and progress bar stall at 100% indefinitely. I, too, had the issue with the error formatting JHFS+ 16GB USB Boot Drive with Patcher Utility. These final tweaks within the last 24 hours seem to have ironed out those issues. Thank you to all who provided input...excellent teamwork and collaboration!
May I recommend creating the Boot Drive USB on the actual 3,1? I have a 5,1 as well and I was getting some errors for some reason that were not occurring when I just performed the patch on the 3,1 computer itself.
May I also recommend as others have to install the Mojave Patcher onto a SSD directly connected to the 3,1's internal drive bays? Super fast this way for the install. Sounds stupid, but disconnect any external drives and more complex cards to keep it simple until you are up and running, then reconnect. This will save you from those random unknowns.
One thing if anyone has better knowledge here: I've seen so many posts on compatible/non-compatible/tweaked Graphics cards for Mojave that my eyes are blurry...I am using in my 3,1 a
HIS IceQ Turbo Radeon HD 7950 DirectX 11 H795QT3G2M 3GB 384-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card that I suppose was flashed for Mac and is showing up as "
AMD Radeon HD 7950 w/ 3GB". Zero issues under HS and Sierra.
Under Mojave, I am not getting video acceleration. How can I? Is it a driver issue? I thought this card was powerful enough and qualified?
