I upgraded to Mavericks last night and ALMOST everything seems to be working (RIP ProTools! Sigh) but my calendar has been "moving calendar to server account" since yesterday with no end in sight. C'mon there wasn't THAT much info on there. I can't close it or even minimize it. I can force close but then I get a big bad error message. Any thoughts on this. Anybody else have this problem?
