Hi everyone, I appreciate this thread. I just unpacked my brand new Mac Mini with the M1 Chip. I migrated things over from my old Intel i5 Mac mini, I followed the instructions listed here to change permissions, installed the drivers as instructed. The Promisestex extensions are in the Library folder, but they are not active. I tried using the terminal commands to load them, but no luck, they are still listed as not active, my Pegasus R6 (thunderbolt) won't mount and I'm still stuck without my data. Any other suggestions from the collective hive? I'm going back to my Intel Mini until I can get this working. I don't want to drop $2500 on a new Pegasus32R6.
I have just discovered that the M1 Pegasus driver (v6.2.16) is now available for download on the Promise support page.
Or you can download it from this link...
Please read the install guide. Big Sur has security features that must be modified.
Enable System Extensions
M1 Mac running macOS 11 or later requires a one-time change to the Boot Policy before you install
the Promise Pegasus Driver. Follow the instruction in this section if the Boot Policy setting has not
yet been changed. First check to see if the Boot Policy needs to be changed
