Additional Details on M Chip Installation
-
The “Reduced Security” setting still provides your Mac with powerful security, only allowing operating systems approved by Apple to run.
-
ACE is actually a standard audio plug-in, not a kernel extension. However, it receives enhanced privileges to access your system’s audio, so Apple uses their existing kernel extension verification system on MacOS 11 and MacOS 12 to allow ACE to load.
