Troubleshhoting Mainstage M1 MacBook Pro

[czar306]

Hi my name is Cesare
I've just moved from High Sierra where I was able to work with SL in Mainstage, but my new configuration (MacBookPro M1 OSX Monterey) doesn't work...Message displayed is: ..."Couldn't open AU component because Apple cannot verify malaware...software needs to be upgraded...contact the developper"....if I try to solve the problem disabling security option the plug-in will be recognised but won’t appear in the list ov usable plugins.
Any suggestions? thanks in advance.

I'll need to build the plugin with a hardened runtime and notarize it, to get past those issues....
