Share calendar accounts on Mac
Share your calendar account with people who use the same CalDAV or Exchange calendar service (for example, with fellow employees at your company). You can choose whether others can edit the calendar account or only view it.
Give another person access to your calendar account
In the Calendar app on your Mac, choose Calendar > Settings, then click Accounts.
Select the calendar account.
Click Delegation, click Edit, then click the Add button .
Enter the name of the person you want to give access to, then choose his or her name from the list that appears.
If you’re giving access to a CalDAV account, select the Allow Write tick box to let the person edit your calendars.
If you’re giving access to an Exchange account, select the person’s level of access from the Calendars column.
See calendar accounts you have access to
In the Calendar app on your Mac, choose Calendar > Settings, then click Accounts.
Select the calendar account, then click Delegation.
A CalDAV account appears in the “Accounts I can access” list.
For an Exchange account, click Add button , then enter the username of the person who gave you access.
To see a delegated account’s calendars in the main Calendar window, select Show.
To see a delegated account’s calendars in a new window, choose Window > [account name].
Make events private
If you have a shared calendar account, you can make private events that can’t be viewed by others.
In the Calendar app on your Mac, double-click or force click an event, then click the event’s date.
Select the Private tick box.
If there is no Private tick box, the event either has invitees or isn’t administered through a CalDAV or Exchange server.
Instead of sharing your entire account, you can share individual calendars.
