I’ve been using Audirvana for several years. I just did a complete wipe and clean Catalina install on my MAC. Now Audirvana either (1) locks up and shuts down MAC when trying to open program or (2) shuts down after playing track for several minutes. There is no other program operating in the background.
This was not a Catalina update. I actually did the wipe and clean install because Audivana was so slow … wheel spinning endlessly. So I wiped the hard drive and started over to clean the clutter.
