Nothing happens when I double click the Duet Mac app to install

Duet should open and ask you to install a graphics driver and restart your computer.

Please login to an Admin account to install

Make sure System Preferences > Security & Privacy setting Allow apps downloaded from "App Store and Identified Developers" is enabled ("Anywhere" also works)

If those don't work then please try to drag the Duet app file to Applications and then try opening again.

If for any reason these steps don't solve the problem, please contact us at – we'd be happy to help out!
