iCal will not sync with Google Calendar after El Capitan Upgrade

Hi, jdemeritt.

Thank you for visiting Apple Support Communities.

It sounds like your Gmail calendar events are no longer showing in Calendar after you upgraded to El Capitan. Let's start with making sure that calendar syncing is enabled under System Preferences > Internet Accounts > Gmail. If this option isn't enabled, please turn this option on and allow a few minutes for the data to download. Check to make sure that the correct Gmail account is added to her internet accounts. Also, make sure to check Gmail.com to verify that these calendar events are present.

OS X El Capitan: Add your Twitter, Facebook, and other Internet Accounts

If the calendar syncing option is enabled, turn off calendar syncing for Gmail and enable it again.

Let me know the outcome of these steps.

Cheers

I had the same issue and found an easy fix (after trying too many complicated ones.)

Go to System Preferences > Internet Accounts

Select Google, then click the minus sign. This removes the account from access to mail, calendars, etc.

Now open Calendar.

Go to Calendar > Preferences > Accounts

Click the plus sign, select Google, and enter your Google email and password.

Now under Accounts, select Google and Enable this account.

I hope it works for those of you who found this conversation and haven't yet found the fix!

Thanks asandeen, this worked for me.

Thanks - that was a big help. It takes a while for the missing events to be repopulated in Calendar, but that worked.

This worked for me, too.
