Both the wife and I have MobileMe accounts and share each others calendars. Some of the appointments aren't showing up on her Macbook Air or the Mac Mini. However all the appointments show up on both iPhones and on me.com on both accounts. Basically they show up everywhere except the Macs. Both Macs are set up correctly to sync with the MobileMe accounts for Mail, Contacts and Calendars. I must be missing something. Anybody have an idea of what may be going on?
