Hello, I recently upgraded to a Mac Mini M2, I initially wasn't able to connect to my Promise Pegasus R4 (model with the Thunderbolt 1/2 connector). I managed to folllow the steps from Promise to install the right extension / driver on my Mac Mini and now the Pegasus R4 is mounted. Everything works fine however for some reason when the mac mini goes to sleep mode I believe, the mac crashes and restarts. The Pegasus R4 is not mounted anymore and I get a message from the mac saying "Your computer was restarted because of a problem". 

If I want to mount the Pegasus I now have to unplug its power cable and plug it again to restard the unit. Does anyone have the same issue?

Hi Thibault,

The Pegasus 1 and Pegasus 2 firmware needs to be updated to the latest version for use with the M1 macs.

The update will fail for a CRC error if you use the latest Promise Utility. To update use the Promise Utility v4.06.0000.01.

Hi, also, if RP's suggestion didn't work, consider making it so your computer doesn't go to sleep in settings, a hack I know, but...
