I I just bought a Mac Mini M1 and Audirvana+. I installed the program and configured the library which is located on an external hard drive. The library is about 4TB of flac files. Almost at the end of the synchronization, the warning of too much memory used and forced closure of the application appears. I tried to restart the system but without solving.
With the same library on Windows NUC system I have no problems neither with Audirvana nor with Jriver.
