How to add a Google calendar shared with me, to my iCloud calendars

A colleague has shared her Google calendar with me. It appears in Google calendar just fine. In the calendar settings I can see the iCal URL, but when I attempt to subscribe to that address in Apple Calendar, it says "A calendar wasn't found on ... Check the URL.".

I suspect this is because the calendar is shared with my via my Google account, rather than been made public. Is there anyway to sync the calendar with my Apple devices? Can I re-share it from my Google account so I can subscribe to it from iCloud?

I tried the syncselect option, which sounded promising, but couldn't see anything happen. I'm not sure how it would work anyway, since I can't see how it would have access to my iCloud account.

Solution 1:

There are two methods:

Method 1:

1. When you open the link of the calendar shared with you. You could click the plus sign at the right corner to add it into your own google calendar.

2. Go to https://www.google.com/calendar/syncselect and check the calendar shared with you.

3. Go to the Mac Calendar and you will find it in your calendar list just under your google account. Check it for display.

Method 2:

1. As step 1 in Method 1.
2. Go to the Google Calendar and the shared calendar appears in the "Other calendars", go to the setting of the shared calendar.
3. Scroll down and find the "Integrate calendar->public address in iCal format" and copy the address.
4. Open the Mac Calendar and go to "Files -> New Calendar Subscription" and paste the address into the "Calendar URL".

Hope this would work.

Solution 2:

Inadvertently found a lovely solution:

1. Go to System Preferences->Internet Accounts
2. Add or select your Google account
3. Click the checkbox next to "Calendars"

Voila, all my Google Calendar calendars appear in Apple Calendar, including the one shared with me. Didn't think there was going to be a solution to this, but so simple once you know.

Solution 3:

This worked partially. I found one additional step I needed to do: the account shared with me is a "delegated" account. So I had to go into Calendar Preferences, Accounts, and click on the delegates tab for my google account - and make sure the delegated accounts I want to subscribe to are checked.
