In case you donât have a backup⊠you can redo your databaseâŠ
If you have Playlists that are important export them first to desktop and save them in a folderâŠ
when Audirvana is reset, you can re-import them back in one shot. sadly to this day, the folders
they were in if so, are not back, you have to do them againâŠ
Apple hide the Home Folder in User Library at some time depending on OS SystemâŠ
When you have clicked your Home Folder, and cannot see the Library Folder in there,
just do a ââcmd Jââ to show the folder settings preferences and see at the bottomâŠ
click Show Library Folder and then youâll have access to the rest forever.
If you continue and trash the database, you will lose also the play count number
of how many times you played those songs⊠if important to you or not.
Go to Audirvana preferences panel and delete with - sign your music folder(s) there.
Close Audirvana.
Go to User⊠Home Folder⊠Library⊠Applications Support⊠Audirvana FolderâŠ
Trash All the files in that folder (that is your database of music, back it up! or not).
Restart Mac. Restart Audirvana.
Add a music folder when asked or go to prefs again and add one with + sign.
LET IT SYNC, even better donât try to adjust windows or edit files, even playing music
while it is not finished⊠youâll see the progress bar going⊠Could be long the first time
depending on how large your library is, and Mac is fast or notâŠ
go to sleep if it is too long. 
Then when finished, close Audirvana, yes close it before playing a songâŠ
That way you will have your database from scratch saved without crashing or bugs.
Then copy the .sqlite file to somewhere else in a folder as a backup for today.
Do this as often you can, if you do many edits in your library or add many CDs, that way
if a bug comes back or doubles, youâll have a not so far library to put back in the same place without bugs.
When copied, reopen Audirvana, and play a song.
