Hello everyone. I'm not sure what I'm looking for here. I use two computers; one for working at home and one for working at work. I use a small portable HDD to work on files I use/need. Is there a way to synchronize both my iCal calendars regardless of which one I enter an appointment into? In other words, how can I add to the other so they are the same regardless of which one I last used, without doing it twice obviously? Does this make sense? The iMac is running 10.3.9. The MacBook is running 10.4.7.
