Hi. I'm using OS 10.8 and iCal 6.0. I moved all my 'on my iMac' calendars to iCloud and now want to move some back. The calendar group 'on my iMac' no longer shows in the sidebar. In several places I have found reference to File -> Calendar Groups, however when I click File there is no option for Calendar Group, only New Event, New Calendar, New Calendar Subscription, Import, Export, Close, Print. Any help for creating a group 'on my iMac'? Thanks.
