Hi Jerry,

Both the Promise Pro utility and Pegasus 32 utility will run on Intel Monterey or M1 Monterey with Rosetta 2 enabled.

I get the following message after upgrading to Monterey


Existing software on your system loaded a system extension signed by “Promise Technology Mobile Apps” which will be incompatible with a future version of macOS. Contact the developer for support.
