Error message on system optimization

i installed today trial version on apple mac mini 2018 i5 version but got an error message below when i turned on

SysOptimization Error
…Not all optimization can be done. Error = The operation couldn’t be completed (OS Status error 22.)

how to solve this problem thanks,

try deleting its preferences…

Close Audirvana

Go to the Main Library Folder… PrivilegedHelperTools folder…
Trash All the files in that folder from Audirvana (that folder install SysOptimizer)
Go to the Main Library Folder… LaunchDaemons Folder…
Trash All the files in that folder from Audirvana (SystemOptimizer and prefs files)

Restart MAC. Restart Audirvana… play song, it will reinstall it :grinning:

I did all of that, rebooted, restarted Audirivan. It asked to re-install the system Optimizer which I did. Then it still has that error message pop-op. I restarted Audixxxx, and it did it again.

way back i posted my files for people who wants to put my files to try to make it works with Audirvana 3.5. they are in my dropbox, you can try to put mine in your folders in the Mac Library, if you don’t have that folder, just drop mine and enter your Mac password. Then after, restart Mac, restart Audirvana and see.
