Soon your Mac will restart to allow the removal of Duet components. Note that you should save your work on Mac before clicking the Uninstall & Restart Mac button.

But what if there is no Uninstall Duet option in the Settings? Or what if your Duet is damaged and cannot be open to access this option? Try the following methods.

Second Choice: Remove Duet in Applications Folder

If the aforementioned method does not work, you could still uninstall Duet from Finder’s /Applications folder and Trash. Here are the regular steps to delete Duet:

  • Open up Finder and head to the Applications folder from the sidebar or Go menu
  • Locate Duet, right click on its icon and choose Move to Trash from the list

Once you thrown Duet into Trash, you can choose Empty Trash from the Finder menu to delete all the items in Trash, but note that it is an irrevocable act and will remove all items there. For the sake of safety, we suggest you to only delete Duet in Trash.

  • Open up Trash, locate Duet, right click on it and choose Delete Immediately
  • Click Delete button in the pop-up window to execute the true removal of the app

  • In an active Finder window, click Go from the Menu Bar, and choose Go to Folder
    Type ~/Library in the box and hit Return key (or click Go button) to open it up


In the folder, utilize the Search feature to find out Duet-related files and folders:

  • Click Search in upper right corner and type Duet (or Kairos) in the search box
  • Under the search bar, click ‘Library’, and delete any item pertaining to Duet
