Note for Apple Silicon
LiveProfessor will run natively on the Apple Silicon CPU where available. If the plugin is incompatible with Apple Silicon, it will fail to load, as the plugin and the host (LiveProfessor) must run under the same CPU architecture.
MacOS should handle this converting on the fly for AU plugins, so you should not need Rosetta for these.
To use other non-compatible plugins and run under Rosetta, right-click (or ctrl+click) on the LiveProfessor application icon and select Get Info, then enable the Open using Rosetta option.
The entire application and all plugins will then run under Rosetta.
