There’s an annoying omission in Reminders in macOS Tahoe (and iOS 26): You can’t clone a list!

Yes, you read that right. No copy and paste, duplicate, or even drag and drop between lists (without moving items).

Apple’s solution: use Automator (really?) or move the list to a template first and then create a new list based on that template. Cumbersome!

Well, ‘Duplicate Reminder List’ solves this annoying problem (until Apple gets to it)!

  • Copy a reminder list
  • Select whether already completed items should come across
  • Stale dates (e.g. due date) get removed automatically.

Done!
