Mac App Exchange Email Calendar
You can set up Apple Calendar to send you an email reminder for any event. You can go to any event on your calendar, add an alert, and there is a drop down list of email addresses to choose from. But how do you change the default email address? Â I was looking everywhere for where to change the email address that Apple Calendar alerts get sent to.
The answer: change your ‘work’ or ‘home’ address in your own contact in Apple Address Book application (Contacts), not in the Calendar Application.
