If you are like me and your iCal Mobile me Sync has stopped working after you’ve updated to iCloud, as you are still running Snow Leopard 10.6 ….this might be a way to get it back up…
Step 1: Backup your iCal (Just incase)
Step 2: Go to iCal > Preferences > Accounts
Step 3: On the Bottom Left Click on the + symbol
Step 4: Add an Account
Account Type: CalDAV
Username: iCloud Username (remember to put the whole email address firstname.lastname@example.org)
Password: iCloud Password
Server Address: pXX-caldav.icloud.com where the XX represents the server it’s hosted on
Mine was p06-caldav.icloud.com, if you are wondering what’s yours log onto iCloud, create an event and invite yourself. When you get the invite click on it, it should open in a web browser and the pXX should be in the URL
If you never receive your email, try to connect to iCloud on a Lion computer. Go to iCal and go to iCal > Preferences > Accounts from there go to the server settings and you should find the pXX in there.
Post a comment if you got it working, or know of an easier way!
