Sync System Calendar with Calendar on MacBook and possibly. other desktop programs allow offline access to the calendar. HOWEVER, this loses a substantial part of the advantages of the system, because in the calendar of MacBook and other programs you do not specify eg. activity results, don’t make a reservation, and more.
1. Click the Apple icon (top left) > System > Preferences Internet Accounts > Add another account > CalDav > account type manually.
2. In the “User” field, enter the name.surname, then “Password” created in the system (see instructions Synchronization).
3. In the “Server address” type: https://dav-app.calendee.cz (the server address corresponds to the domain eg. https://dav-domena.calendee.cz)
4. Click “Log in” and the account will be saved.
5. In the “Usage” field, check Calendars and Reminders. Then close the Internet Accounts window.
6. In the newly opened calendar, make sure that all color-coded calendars with activity names are checked for display.
We do NOT recommend editing repeated activity in a synchronized calendar in apple.
