Before contacting support
- Check the FAQ. Most "does it do X" questions are answered there.
- Run Preview (not Copy Events Now) and check the Options screen's Activity Log for what LocalCalSync saw and planned to do. Include that log when you report an issue. It's the fastest way to diagnose a sync problem.
- Confirm both calendars appear in Apple Calendar itself (open Calendar.app directly). If a calendar isn't visible there, LocalCalSync can't see it either.
Common fixes
- "Allow Calendar access" won't go away: open System Settings > Privacy & Security > Calendars, enable LocalCalSync, then quit and reopen the app.
- A calendar I expect isn't in the picker: it needs to already be added as an account in macOS (System Settings > Internet Accounts, or your organization's provisioning profile), and it needs to actually contain events for the window you're syncing.
- Two calendars have the same name: the command-line fallback script can't always tell calendars with identical display names apart. Rename one in Apple Calendar, or use the Mac app's picker instead, which lists both the calendar name and its account.
