Apple Calendar
ICS subscriptions, refresh cycles, and adding calendars.
How Apple Calendar sync works
Apple Calendar subscribes to an ICS feed from Sync2Cal. Updates depend on the app and subscription settings; use iCloud if you want the calendar on multiple Apple devices.
Events not showing in Apple Calendar
Check subscription visibility, iCloud account, and refresh settings when Apple Calendar events are missing. Avoid re-adding the feed before checking the existing subscription.
How to add a calendar to Apple Calendar
Add a Sync2Cal subscription on iPhone, iPad, or Mac. Choose iCloud to make it available across your Apple devices and check that the calendar is visible.
