DSP Trigger does not show up in MacOS 12

[haugbui]

DSP Trigger does not show up at all in Ableton Live 11 under MacOS 12.2.1
I also tried other software than Live, and it did not work.
DSP Trigger works fine in Live 9 under MacOS 10.10.5

Is there a compatibility issue with MacOS 12?

Have you rebooted? Often plugins won't show up until after a reboot.

That did the trick, thanks!
