How do I disable alarms?
Alarms can be disabled either by having the macOS Calendar application remove them, or by disabling them at WebCal.Guru. This process shows how they are disabled from the subscription at WebCal.Guru. Disabling the alarms can be done with any device.
Note that the macOS Calendar application may also add alarms to events even though the calendar does not contain them. Please take a look at I have not enabled alarms, but I still get them. as well.
Step 2
Click the tab Alarme and set both alarm settings to Keine.
Step 3
Click Speichern.
The new settings take effect the next time your application downloads the calendar data, usually within a day or so. If you wish, you may tell the Calendar to refresh the data immediately. Open the Calendar application, open the View menu and select Refresh Calendars.
