The only configuration to have official plug-and-play beta support with macOS High Sierra 10.13.3 is a Thunderbolt 3 Mac connected to the Sonnet Breakaway Box Developer Edition, which is bundled with Sapphire Radeon PULSE RX 580 8GB card. High Sierra support for the Developer Edition will be beta until spring 2018. Because it is currently beta there are some temporary limitations. For example, the external graphics card currently accelerates only external displays connected to the graphics card. Note that you will not be able to obtain support from Apple or AMD for external graphics under macOS at this time. If you have any issues using any Sonnet product, please contact Sonnet customer service at
