I recently clean installed Yosemite on my 11" Macbook Air and my Google calendar will not sync with Calendar.app. Everything else on my Google account syncs with no problem, but the calendar refuses. I tried with another google account and had the same problem. Turned off 2-factor auth, same problem. Tried with CalDAV, doesn't work.
In Preferences > Internet Accounts > Google Account in Question, the box next to Calendars is unchecked by default. When checking it, I get a progress wheel that spins for a minute or so and then...nothing.
Is there something I'm missing here?
