I upgraded from a 2015 iMac with a 4GHz Quad-Core Intel Core i7 to a 2022 MacBook Pro 16inch 2021 with M1 Max.
When I trie to cponnect either my Pegasus3 R6 or Pegasus2 R8, it is not mounting, nor is it showing in the promise utility.
When I tried to connect it back to my old iMac, the same problem occurred.
The devices are showing in the system report of both computers, and all the lights on both units are blue. Both computers are running Mac OS Monterey Version 12.1, and the promise utility is up to date with version 4.06.0000.01 (C02).
I tried everything I found in this forum and others to no avail. All sorts of re-starting processes, using different cables, only one at a time instead of daisy chained, etc.
