What do you need help with?


*We recommend staying on macOS 10.13.3*

Installing macOS release Version 10.13.4 will cause Duet Display stop functioning after the OS upgrade. We have alerted Apple to this issue and are working hard to find a resolution. These features continue to work as expected in 10.13.3.

We would strongly recommend contacting Apple though their bug reporting (https://developer.apple.com/bug-reporting/). It will help have the bug prioritized if Apple is aware how many people are affected by this issue.

We are actively looking into workarounds so that duet is not affected by the macOS bug, and will keep you informed. Please e-mail us if you have any questions. Thank you for using duet.
