Cant view calendar on iMac.
I can't view my calendar on my iMac. When I open Calendar, I see the menu bar and can view that, but nothing else. Many of the items on the drop down menu are greyed out and the few I can click on, result in nothing happening. It's fine on my iPad and iPhone, just not on my iMac.
Tired to restore it from Time Machine and I get the warning that I can't alter Calendar.
Any suggestions/help? It's been about a week ago that this started.
