The one problem I’ve found when upgrading to Lion is that suddenly iCal couldn’t sync to my Google Apps Calendar account – instead it repeatedly asked for the password. I’m still not really sure what caused this, but my solution was to simply delete both ~/Library/Preferences/*iCal* and ~/Library/Calendars. You really only want to do that if you exclusively use Google Calendar. If you have local calendars deleting ~/Library/Calendars will delete them.
Once I’d done that, I re-enabled the Calendars option for the account in System Preferences, “Mail, Contacts and Calendars”, entered my password one last time and it worked perfectly.

Hi Adrian,
Having the same issues as you since upgrading to Lion.. how exactly do i do the steps you’ve mentioned? I tried looking in Library>Prefrences but can’t find any iCal references at all. Please could you show some specific steps and locations as this is really bugging me!!
Thanks in advance for your time.
Jason

Hi Jason,
I did it from the command line, so open Terminal and run:
rm ~/Library/Preferences/*iCal*
rm -rf ~/Library/Calendars
Be *very* cautious about this as it will delete any local calendars and remove all your iCal preferences, settings etc. You’ll then need to set it up again to sync with Google Calendar.

I couldn’t find the path, can u please specify whether to look in the user’s library or in the general one
Adrian Sutton says:
It’s under the user’s library folder. The ~ in the paths above are a shorthand for the user home directory. That said, you should just be able to type the commands above into Terminal exactly as-is and they should work.

“Worked perfectly” as in synced ical and google, or just erased ical and now you just use Google? I’m unclear and don’t want to proceed until I’m clear as I use both unfortunately due to ease on the iphone of ical. Just trying to figure out how to most easily sync them :) LONO

This process will permanently delete all your local calendars. I’ve always just used Google to store my calendars and synced them over the air to my iPhone and iPad using caldav. You’d need to very carefully export your local calendars and reimport them afterwards but I’d be doubly certain you have a good backup before trying anything like this.
It’s probably also possible to only delete the Google calendar cached files and settings but I’m not sure how you’d tell the difference.
