Google Calendar doesn't sync with Calendar macOS

WesleyReboucas,

Thank you for those details. Let's attempt to test while in safe mode:

"Start up your Mac with Apple silicon in safe mode

1. On your Mac, choose Apple menu  > Shut Down.
2. Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.
3. Press and hold the power button on your Mac until “Loading startup options” appears.
4. Select a volume.
5. Press and hold the Shift key, then click Continue in Safe Mode.
6. The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.

Start up your Intel-based Mac in safe mode

1. Turn on or restart your Mac, then immediately press and hold the Shift key until you see the login window.
2. Log in to your Mac.
3. You might be asked to log in again.
4. On either the first or second login window, you should see “Safe Boot” in the menu bar."

Additional details can be found here: Start up your Mac in safe mode

If the issue persists, can you provide a few more details? Do you notice any connection issues with other functions on your Mac or only when connecting to Google? Can you test with another network? Also, what is your exact macOS version?

Cheers!

Good day to you WesleyReboucas, 

We’re going to recommend some basics to begin as they can resolve these types of issues by refreshing the Calendar app itself.

If you haven’t already, be sure to quit and relaunch the Calendars app. If the issue is persisting, restart your Mac. Shut down or restart your Mac

At that point, if the issue is persisting, we’re going to next suggest removing and re-adding the account to the Calendars app. You can do that a couple ways. Remove the account in Settings > Calendars > Accounts. Or if the account syncs other items, such as mail and contacts then just turn off Calendars, restart and then enable it again. 

Thanks.
