macOS 10.13.4 support

We recommend staying on macOS 10.13.3 or upgrading to 10.14.2 +

This issue is completely resolved in 10.14.2 and later

Installing macOS release Version 10.13.4 will cause Duet Display to not function at full performance after the OS upgrade – these features continue to work as expected in 10.13.3.

We would strongly recommend staying on 10.3.3 or upgrading to 10.14.2, which fixes the issue. Please e-mail us at if you have any questions.

Thank you for using Duet!
