Every reminder keeps a log, so shared reminders stay accountable.

1. Open the reminder menu and choose History.

2. Each entry shows who made the change and when, and whether it was a creation or an edit.

3. Changed fields are listed with their before and after values, such as the event date or the alert times.

The history is read-only. To correct something, use Edit on the reminder; the change is then recorded as a new entry.
