I'm about to give my iCal on my Mac a makeover and restart it but I'm wanting to know if I can make it on my MacBook but then synchronize it to my Mac Mini?
If I understand, what you want to do is copy iCal between two Macs. What I do is back up iCal (File>back up iCal) then email it to myself. I then drag the iCal back up on my other Mac into iCal. I guess you can also try Mobileme. MC
I just switched over to Google Calendar though - you can load GCal into iCal, and the syncing between machines is much less buggy than through the method above.
