Titan Ridge (flashed) Opencore 0.7.7 Mac Pro 5,1 Big Sur
 

Hi, just posting this to see if anyone else has this setup and the issue I have found. I am not using a Thunderbolt interface just using the titan ridge for USB C hard drives like Sandisk Extreme Pro. For some reason even though I am not using a thunderbolt drive, when I boot up and start a pro tools session running off my Sandisk extreme pro which is USB 3.1 v2 that's connected to the Titan Ridge, Pro Tools locks up and the finder disappears, then I force quit pro tools and reboot and then the USB C drive connected to the Titan Ridge no longer shows up in the finder and I have to unplug and plug it back and then it mounts. Then I launch pro tools and open the same session and all is ok. So it's like Pro Tools thinks its connected to a thunderbolt drive and it crashes as the driver is not loaded until the reboot or something along those lines.

Ok so to follow up. The issue seems to be that I had two system hard drives with the same name as in "Macintosh hd" mounted at the same time, Pro Tools doesn't like this and it creates an error but for some reason I was not getting a visual like AAE error etc but I did when I ran a different session off an internal drive. Looked up the error and found out it was because of the two matching drive names.
