Update: Google appears to have fixed the sync issue. If you still have problems, read the bottom of this article.
A few days ago, something broke with Google’s calendar synchronization as it works in macOS and for some iOS users. Complaints abound on Google’s support forums, but no solid answers have emerged at this writing.
Many people have tried a variety of techniques, like changing events, removing cached local calendar data in macOS, and other tactics. None have worked, or only work briefly before the calendar disappears again.
We’ll update this article when a solution appears. But never fear: It’s not just your account or device.

Google Calendar sync is currently broken, but it’s not your fault! (Screen blurred for user privacy.)
Update: How to fix lingering sync problems
If you still have sync issues after August 23, you may need to delete the local cache in macOS:
- Launch Calendar and uncheck Google calendars in the Calendars list.
- Quit the Calendar app.
- In the Finder, use Go > Go To Folder and enter
~/Library/calendars/
and press Return. - Delete all items with the word “cache” in the name.
- Launch the Calendar and re-check the Google calendars.
