I use Reminders quite often, it is a great little tool which additionally stays in sync with your macOS and iOS devices.
One drawback though ...when a reminder is marked as "completed", the reminder will not be deleted and instead just hidden.
So how do we purge these completed reminders/tasks, as there seems to be no function in Reminders to a do a cleanup.
Thank goodness for AppleScript ... in Terminal execute:
osascript -e 'tell application "Reminders" to delete (reminders whose completed is true)'
We use osascript to execute an applescript statement, which tells the Reminders application to delete all reminders that have been marked as completed.
Note:
- if you have used Reminders for a very long time, and completed tons or reminders, then i may take a little time for this to complete initially.
- I also found it to be better to keep the Reminders application minimized while executing this.
