How to make Calendars work with iCloud, iCal, and Mac OS X 10.7.2

I had some troubles after the update to Mac OS X 10.7.2 with syncing iCloud Calendars with iCal. The main problem was my iCloud calendars weren't showing up in iCal. Here's how to fix it.

  1. Open iCal, go to iCal -> Preferences -> Accounts, and turn off any other accounts which might be syncing with this Mac (in my case, I was synching with Gmail). This may not be necessary, but I don't want a bunch of different calendars messing things up.

  2. Quit iCal.

  3. Open System Preferences -> Mail, Contacts, and Calendars.

  4. Select your iCloud account.

  5. Uncheck the “Calendars” option for your iCloud account, and read the alert it shows you. Confirm it.

  6. Then re-check the “Calendars” option for your iCloud account. This will throw up a different alert. Read it and confirm again.

  7. Now open iCal again, and you should have your iCloud calendars, and only those calendars.
