My last Mac was still using iCal, so now I'm getting up to speed on the mostly-similar Calendars. So please forgive my ignorance in advance.... I created my usual bunch of calendars and everything was working fine. Then I figured it would only make sense to put them on iCloud where my remote devices could view/modify them. I did this, and my new iCloud calendars worked great too. But now I see that I ONLY have my calendars in iCloud; when I'm not logged into iCloud, my Calendars vanish into thin air. Does this mean that I'm stuck with using Calendars via iCloud or offline, as an "either-or" situation? Can't I simply maintain my Calendars offline, pushing them up onto iCloud periodically just to have a current version accessible on the go?
