Cant open vst version in Studio one? SOLVED

[LoFiLeiF]

Did you use the latest version of the MG2 software?

Midgiguitar2.component - incompatible in Logic 10.7.2 and gives error message in UAD LUNA as well

The reason is that you have the old (pre-MacOS-Catalina) version of the AU. Please get the newer one: Download – Jam Origin. Make sure you overwrite the old .component.

It could also be a security/privacy settings issue of course:

Ableton won't recognize developer

Please try and set macOS security settings like shown: [23]
