Calendars are greyed out or context-menu options are disabled

If a calendar in the left sidebar is greyed out and most right-click options are unavailable, it’s usually because that calendar is currently unsubscribed (or hidden via a view option).

Fix: Re-subscribe to the calendar

1. In BusyCal for Mac, open the View menu.
2. Enable Show Unsubscribed Calendars.
3. In the Calendar List sidebar, find the greyed-out calendar and click the faded checkbox next to it.

Once it’s re-enabled, BusyCal will subscribe to it again and the normal context-menu options (Get Info, Unsubscribe, etc.) return.
