Step 5: Once you’ve selected permissions, click “Done.” They’ll receive an invitation via email or directly in their Calendar app.

With these steps, you can share calendar from Mac quickly and easily. It’s ideal for coordinating with family, teams, or project groups.

Click “Done.” Now, nobody you’ve shared it with will be able to view it anymore.

The person will receive an invitation. Once accepted, they can view or edit the calendar, depending on the permissions you’ve set.

Part 3. Why Can't I Share My Calendar with Someone?

Sometimes users run into issues when trying to share calendar from Mac or iPhone. Here are common reasons why it might not work:

1. Calendar Is Not iCloud-Based

You can only share iCloud calendars. Local calendars or calendars from other accounts like Gmail or Exchange won’t support sharing through iCloud.

2. Incorrect Apple ID

If the recipient isn't using an iCloud account or you typed the wrong Apple ID email, sharing will fail.

3. Permissions Glitch

Sometimes, permission settings may not save correctly. Try removing the person and re-adding them.

4. Outdated Software

Ensure your macOS or iOS is up to date. Outdated software can prevent features like calendar sharing from functioning properly.

5. iCloud Sync Not Enabled

On both devices, go to Settings > [Your Name] > iCloud and make sure Calendars is toggled on.

If you’ve tried all the above and still can’t share calendar from Mac or other devices, try signing out of iCloud and signing back in. It often resolves minor syncing issues.
