Please consider this a sequel to a previous Pointers about Syncing Google and Apple Calendars. Please consider it a relief, too, as we wrote that article to help us figure out a problem and now that problem has been taken away from us. We no longer have to juggle both calendars and the first new event we added afterwards was a party to celebrate this fact. You can juggle both, you may well need to and that previous Pointers will tell you how, but the short version is that mixing two of anything is terrible.
