New macOS High Sierra 10.13 has been released few days ago. At this moment there is no NVIDIA drivers with eGPU support available for High Sierra. We expect them to be released in next few weeks.
– If you are using macOS El Capitan or Sierra, please, do not update until drivers will be released. eGPU is fully functional in macOS Sierra or El Capitan.
– If you have already updated, you can downgrade to the previous version of macOS. Please contact our tech support team and they will guide you.
IMPORTANT: It’s not a BizonBOX issue. All the external graphics chassis on the market have the same limitation.
We are sorry for any inconvenience.
