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 the previous section I have not enabled alarms but I still get them. Why? as well.
