I have to reset my library, because of many tracks are visible treble. 
I read https://audirvana.com/forums/viewtopic.php?f=5&t=1345, but the instructions there don´t help (I did not find the suggested folder “Audirvana” like it says in the advice “Go to User… Home Folder… Library… Applications Support… Audirvana Folder…”). I suppose the re-installing of A3.0.6+ would not be enough. Is there a way for resetting the library without deinstalling the software?
Thanks

If you have Playlists that are important export them first to desktop and
save them in a folder… when A+ is reset, you can re-import them back.
sadly to this day, the folders they were in is not back, you have to do it again…
Before doing this, maybe you should not connect after deleting those files to Roon or others…
install A+ alone with your database… if working, log to Roon or else after 
Apple hide the Home Folder in User Library at some time depending on OS System…
When you have clicked your Home Folder, and cannot see the Library Folder in there,
just do a ‘‘cmd J’’ to show the folder settings preferences and see at the bottom…
click Show Library Folder and then you’ll have access to the rest forever
Starting for new A+:
Go to the main Library Folder… PrivilegedHelperTools folder…
Trash All the files in that folder (that folder install SysOptimizer)
Go to the main Library Folder…LaunchDaemons folder…
Trash All the files in that folder for Audirvana (SystemOptimizer and prefs files)
Go to User… Home Folder… Library… Applications Support… Audirvana Folder…
Trash All the files in that folder (that is your database of music, back it up!)
Go to User… Home Folder… Library… Preferences…
trash com.audirvana.Audirvana-Plus.plist in that folder (those are A+ software preferences)
Go to User… Home Folder… Library… Caches… com.audirvana.Audirvana-Plus
trash the files in that folder
Restart MAC just to be sure… This will reset pretty much Audirvana like new.
When choosing library at first it will sync in top right main window under the logo…
LET IT GO, even better don’t try to adjust windows or edit files, even playing music while
it is not finished… you’ll see the progress bar going… Could be long the first time
depending on how large your library is, and MAC is fast or not… go to sleep… then see
Thanks a lot! It works. Now I can see the hidden Home folder and so on. I could reset the library successfully.
