In the wake of last week's release of Mac OS X 10.5.3, the Apple Discussions forums have been flooded with myriad threads related to innumerable iCal problems! I can concur that the latest Mac OS X 10.5 Leopard update wiped all my iCal calendars, following a .mac sync, and replaced these with empty duplicates!
Thankfully I had a usable backup from which to restore all my calendars! This is my suggested workaround:
*Uncheck iCal sync (System Preferences/.mac)
*Delete this folder: ~/Library/Calendars
*Restore all iCal settings via your backup plan
Hey presto! A working copy of iCal. Your mileage may vary, but I hope that this simple tip will help some (if not all) affected users. Further to this, I'm seriously considering purchasing Time Capsule 1TB at the conclusion of WWDC 2008!
