Getting it to work on Monterey 12.2.1

[blisst]

This issue is informational for anyone who has problems on Monterey 12.2.1.

When I first upgraded to Monterey, connecting my Presonus Firestudio was freezing my system when it was plugged in and powered on.

TLDR: The answer was to make sure all aggregate audio devices in Audio Midi Setup were NOT using the Firestudio before plugging it in.

If that doesn't work for you, it may have helped that I did the following to reset permissions on the Presonus kext files.

1. Uninstalled the Presonus Firewire drivers via Presonus's official DMG.
2. Restarted into Recovery Mode (hold Cmd + R on restart)
3. Go to Utilities > Terminal at the top.
4. Run kmutil trigger-panic-medic --volume-root /Volumes/YOUR_HD_DRIVE_NAME which I found from this guide
5. Restart
6. Reinstall drivers using the latest release from this repo (0.4.0 at time of writing)
7. Restart
8. Go to Security & Privacy, click Details next to the "software not being allowed" part at the bottom.
9. Make sure Presonus is checked (allowed) and hit OK
10. Restart
