Change default event notification sound


Edit EventAllDayAlarms.icsalarm and EventTimedAlarms.icsalarm for the relevant calendar under ~/Library/Calendars. Change ATTACH;VALUE=URI:Basso to the name of the new sound.

Note files are overwritten when you change calendar preferences.

Sound file may need to be in /System/Library/Sounds, which won’t work under SIP.

Why is this so hard?!?

Create local-only calendars

In short:

  • Switch off Calendars for all accounts in Internet Accounts that use them.
  • Add a new calendar (File ▷ New Calendar ▷ On My Mac).

Re-enable calendars in all accounts that use them.
