Thank you
@h9826790. I followed your #
1314 post and installed OpenCore 0.6.6 (and a fresh install of Big Sur) on my Mac Pro 5,1 yesterday. Both OpenCore and Big Sur are on a NVMe (brand and model below) and are working great. I've confirmed with VideoProc that I have HW GPU working.
I have a few of issues though. Anyone is free to chime in and help
Filevault not working
When I try to turn on FileVault on the Big Sur OS drive, I get an error that says 'FileVault failed: Incorrect Password'. Is this to be expected or is there a way to get this working?
Thunderbolt only works from warm boot
I have a flashed GC-Titan Ridge Thunderbolt card (with pin 3 to 5 jumped). I have CalDigit T3 dock which is connected to a LG 5K (daisy chained). I've enabled Thunderbolt (following the YouTube video example by changing the config value to 'true'). Both the T3 dock and the LG 5K now work, but it needs a warm restart before the OS can see them. Is this to be expected? Or is there a way to have it work from a cold boot?
I've had cold boot Thunderbolt working previously. About a year ago I had Catalina installed on this Mac Pro through a version of OpenCore by a github user named fancyXI – it was a version specifically for the Mac Pro 5,1 and the GC-Titan Ridge and it allowed Thunderbolt to work from a cold boot.
Looks like his OpenCore repository is down though. It was an older version of OpenCore and the Brightness/USB/Webcam didn't work on the LG 5K (unlike version 0.6.6) but like I said, it did work from a cold boot. For the record, this install of Catalina (and the older version of OpenCore) were removed months ago and I reverted to a fresh install of Mojave).
Sleep not working when GC-Titan Ridge is installed
I think I read something about how sleep doesn't work if you have a USB 3 device connected via Thunderbolt. Is there a way around this or is this a dead end?
These are my specs…
Mac Pro 5,1
2x 3.33Ghz
128GB RAM
Big Sur and OpenCore on NVMe (PNY XLR8 CS3030 1TB)
MacVidCards Radeon RX 580 8GB
GC-Titan Ridge Thunderbolt Card (Flashed)
LG 5K Display
Once again, thank your for breathing new life into this old beast!
