To fix the "Calendar has not been selected" red box error when adding events in Timepage, follow these steps:

1. Check your Calendar accounts on your Mac:
- Go to System Preferences > Internet Accounts.
- Confirm your calendar account (e.g., iCloud, Google) is added and calendars are enabled.

2. Verify calendar selection inside Timepage:
- Open Timepage.
- Tap Menu > Preferences > Calendars > Setup Calendars.
- Ensure the calendar you want to add events to is selected (checked) and visible.

3. Confirm Timepage permissions to access calendars:
- Go to System Preferences > Security & Privacy > Calendars.
- Make sure Timepage has full access enabled (not limited to Add Only).

4. Check sync settings on your calendar accounts (if applicable):
- For Google or other accounts, ensure push or fetch settings are correctly configured for syncing events.

After confirming these settings, you should be able to add events without the error. If issues persist, contacting Timepage support is recommended1 3.
