What password am I supposed to use?
Last week, I "upgraded" to OS Catalina. This screwed up several things. My Firefox browser is pretty much useless -- even after updating it -- and my Logitech wireless mouse lost the zoom, back/forward, etc., settings I had. Another thing it did, for some reason, was lock out my Apple id. So, not only was I unable to sign in and ask questions here, but I also couldn't fix the mouse, because I needed to sign in/unlock the preferences. FINALLY got my account unlocked today, and reset the password. Tried to fix the mouse, but when I typed in the new password, the box began shaking. (I assume that means, "no?") I tried the last 2 passwords I had, but those didn't work either. So, how exactly am I supposed to unlock it? Is there some other password I need? (I understand the need for security, but what the heck good is it if I can't even get into my own computer?!?!) I'm using a 2012 Mac mini. (Does this mean I'm due for a new computer? If I am, it sure as heck won't be an Apple . . . )
