TU3-DS2 macOS 10.13.4 Compatibility
June 12, 2018 – Installing macOS 10.13.4 will cause any connected displays to go blank after the OS update when using the latest driver. Extended or mirror displays continue to work as expected in macOS 10.13.3, and we can only recommend that you stay on macOS 10.13.3 or earlier if you require this feature and have not already updated. Functionality such as Ethernet and audio are unaffected. We are working on a fix and updates will be posted on product download pages once available.
