Recurring error pop-up in MainStage 3.6.6 with no apparent cause.

Recurring pop up "An Audio Unit plug-in reported a problem which might cause the system to become unstable. Please quit and restart MainStage" happening since December 2023. I have validated all AU plug-ins using both AUVAL and the plug-in manager. All pass. Some users indicate this is a bug in Ventura and Sonoma audio handling. Any help would be appreciated



Mac mini, macOS 13.6

Find MainStage in the Applications Folder using Finder. Highlight it and then "show info" by pressing Command I. There is then an option to tick to "Open using Rosetta". The next time you run MainStage it should open using rosetta.


I assume as you've asked you are running on an ARM processor? If not, the Rosetta option will not be offered.
