Apple calendar for mac outlook add users calendars

I use Fantastical and Apple’s Calendar on my Mac, Fantastical on the iPhone, and Calendar on the iPad. Today, I rely on Google Calendar to keep my appointments in sync between my Mac and my iOS devices.

That hasn’t worked since the late 1990s, though.

There was a time when I managed my calendar by keeping a Post-It note with important meetings written down on it.
