Okay, so upgrading to iCloud, I noticed that iCal had duplicated all my events. What I did NOT realize at the time was that it wasn't a random error. Anyways, I went through just deleting some of the events randomly.... Not a smart move :/ My question is this: If I have a time Machine Backup (I do) can I erase ALL iCal data and then restore from time machine, and THEN sync everything back to iCloud? (and not accidentally delete the duplication this time?) I would appreciate any advice. My stupidity + my excitement = this predicament and I have a TON of calendar info.
