Getting Started: Mac Support

Download and install for Mac

Download the latest macOS version from here – requires macOS Big Sur or later. If you wish to use Duet on an older macOS, please reach out to us at team@duetdisplay.com for further assistance.

To install the app, please double-click on the .app file, which will install Duet in your Applications folder. Once installed, you will see the app's icon in the menu at the top right of your Mac (a lower case d with a circle around it). If you need to change any settings, click on the menu bar icon to open Duet's UI on macOS.
