Open the macOS Calendar application.
Calendars are processed by the calendar application and that's where they're unsubscribed. Unsubscribing can only be done in the macOS Calendar application, not at WebCal.Guru.
The removal process has changed in the newer versions of macOS Calendar. If you're using an older version, please take a look at calendar removal in older versions of macOS Calendar.
Double-click on any event in the calendar you wish to remove. In this example, such an event is the Labor Day.
A window opens showing the details of the selected event. At the bottom of this dialog, click the Unsubscribe button.
If there is no Unsubcribe button, there are two possible reasons:
A dialog opens to confirm that you really want to unsubscribe. Click the Unsubscribe button.
Please note that this will not only remove this particular event (Labor Day in tbis example). Instead, it will remove all events in that calendar. In this example, that calendar is US Federal Holidays.
