Help! Where are vst2 and vst3 in ableton 11 osx M2? onle see au2
Did you enable to scan VST folders in Ableton?. Keep values by default except if you have installed your VST in a specific folder Ableton/Preferences/Plugins if I recall the place
First, if you are a customer you can always ask the support mailing list.
But: It is almost definitely the case that you are running ableton in native, not rosetta mode. Rack is an x86 only bit of software.
The AU format allows ARM hosts to run X86 plugins. The VST formats do not unless your DAW has built process bridging, which Live for mac has not.
So if you want the VST versions of rack in live on an ARM mac you need to run live under rosetta (which will mean that all your other plugins run under rosetta if they are universal; which may or may not be what you want).
