Notes app on Mac Mini (late 2014) disappeared
How can I get all my many notes entered in the app Notes on my Mac Mini? The screen had turned a dark red/purple overcast, so I restarted. Screen was fine after restart, but Notes app is now blank. I had dozens of important notes. How can I retreive them all? I use Time Machine and an external HD (iDrive). What's the name of the file I'm looking for? How can I find it? Any other advice?
Thanks,
Dan
