Since Thursday, I have not been successful in updating iCal on my Macbook Pro. When I make changes to iCal on my Macbook, iCal starts the updating process but never finishes. New entries continue to have a check mark next to them (showing that they haven't been updated to the server). I have an iPad and iPhone and cannot sync my calendars between the 3 devices. However, I can successfully log in to MobileMe and access my iCal file this way and have been able to update it. This method has enabled me to sync my iPhone and iPad. Why should I be having problems only with the desktop calendar? I have not yet upgraded to iCloud and am still using MobileMe sync.
I am using the newest version of Lion.
Emily...I do not have a fix but there seems to be a pervasive problem with iCal sync (whether MobileMe or iCloud) once the MacBook Pro is upgraded to Lion. There are at least five threads about this dating back to 10/14/11. No one has had a solution. I have an appt to speak to Apple Support tomorrow morning. Keep your fingers crossed.
