Cannot find/delete library DB [Solved]

OK to get around the network drive issue in the new osx Sierra I’ve moved my music over to a local USB drive and then backing that up to the NAS.

I want to purge the library and start again but I can’t find the database, it is supposed to be located at /users/ME/Library/Roon/ but the /Library folder doesn’t exist on my hard disk or nothing like it on the music folder on my NAS.

Have even tried searching the entire Mac for “roon” and it just lists the app in the applications folder

The Library folder is hidden by default on MacOS. You can enter it by “alt”-clicking “Go To” in the top menubar and select Library. (You need to hold the alt-key until you have clicked “Library”.)

Thanks, got it now.
