- someone sends me an iCal calendar invite via email
- Mail offers to add to my calendar, in Apple Calendar.
But…. I use Daylite and would prefer to add it there.
I discovered a trick to open calendar invites in BusyCalendar, probably will work with Daylite too.
Here’s the procedure: in the Finder, find the attachment for a calendar event (a file with .ics extension), select it, choose “Get Information” from the File menu. Select the “Open With” pulldown, select the app you wish to use (Daylite in your case), and make sure to press the button directly below, “Change All”. I did this also with .vcf files (which used to open in Apple Contacts, now they directly import in BusyContacts).
