How do I set up a calendar with CalDav in MacOS calendar?

To set up a calendar using CalDAV in the Calendar app on macOS, make sure that you have activated the appropriate option on the mail.mybox.com side according to the guide available HERE.

Open MacOS System Settings, then select Internet Accounts. Click Add another account.

Select that you want to add a CalDAV Account

In the window that appears, select the following sequence:

• account type: Manual
• user: Username obtained when adding the calDAV connection in mail.mybox.com
