Ask any music professional (someone who actually makes $$ doing all this stuff): don’t upgrade your OS *until* you check that your key plugins are ready to go with a new version of the OS. Especially MAC OS! I made the PC to MAC jump a few years back, and when I updated to Catalina, I found out the hard way. I’m a hobbyist, so I just waited till the plugins caught up. which didn’t take too long. Don’t bang your head against this wall would be my advice. I know better this time, I am waiting for the all clear from Native Instruments before I head in. Here’s a useful resource:

Oh wait — I should’ve taken my own advice. and I quote:
All Eventide and Newfangled Audio plug-ins are compatible with macOS Sonoma.
AAX, AU, VST2, and VST3 natively support Apple Silicon and Intel processors
Important info for users running Intel machines or GarageBand under Rosetta: Eventide plug-ins cannot currently be opened in GarageBand 10.4.4 on macOS Big Sur, however they will open in GarageBand 10.4.5 on macOS Big Sur. Eventide plug-ins cannot currently be opened in GarageBand 10.4.4 and above on macOS Monterey and above. Please hold off updating GarageBand until this issue is resolved.
Windows 11: All Eventide and Newfangled Audio plug-ins are 64-bit only.
There may be some DAWs that do not yet support macOS Sonoma, so it is important to check your DAW’s website for compatibility info before updating.
