If you publish or share calendars, you may want to refresh them so that others can see your latest changes. Or, if you subscribe to calendars, you may want to check for updates periodically to be sure you have the latest information.
Refresh a calendar you publish. Control-click a calendar below On My Mac in the calendar list, then choose Get Info. Select “Publish changes automatically.” If you don’t see the calendar list on the left, choose View Show Calendar List. If your calendar list doesn’t have an On My Mac section, your calendars are in an account.
A published, shared, or subscribed calendar has a Share Calendar button next to its name.
