Lion killed iCal syncing
After I upgraded 3 machines to Lion iCal syncing via MobileMe stopped working on every lion machine. ICal always shows "Syncing..." but nothing happens. There is neither a problem syncing my iPhone to MobileMe nor with my iPad. Everything works fine with iOS 4 and MobileMe.
How do I get iCal on my Macs working again?
