Hello All, Yesterday my MBA 2012 was getting this message upon login: "Finder Unexpectedly Quit" It gives me the option to Ignore, Report, and Reopen. If I click on any of these, a new window pops up saying that finder unexpectedly quit. After 3 or 4 times, my computer becomes stuck on the rotating circle. I cannot click on anything - no applications, no console, no terminal. Any advice is appreciated. I am going to see the Genius Bar later today.
