@Dan-Korneff Yeah iLok were in touch, Oek Sound too, now I got this from Kilohearts:
Unfortunately, we have to join the chorus of audio software developers advising users against upgrading your MacOS to Sonoma 14.4.
A few users have reported various problems with Kilohearts plugins in the latest MacOS update and we are in the process of working out what is causing them and finding a solution.
@d-healey Oh actually perhaps I can check if the text file exists and if it doesn't then the app knows it's not the latest version... (I'm about to issue the required plugin update)
