  • Currently, Mac systems only support HDMI 2.1 via direct connection to the Mac's built-in HDMI port. Mac users can get HDMI 4K @ 120Hz on supported Macs by directly connecting to a system’s HDMI port. Mac users will only experience 4K @ 60Hz through the HDMI port of the connected Thunderbolt Go Dock.
  • Mac Users: A software driver is required to enable Apple Super Drive, Apple USB Keyboard, and for charging iPad generations 1, 2 and 3. This driver is included in the OWC Dock Ejector software download package. If your SuperDrive doesn't respond when connected to an external display or USB hub, connect your SuperDrive to a USB port directly on your Mac.
  • Recorded sound input playback will be quiet. Adjusting the input volume in System Preferences does not improve the softness of the recording playback. Connecting the desired input directly into the computer system will improve the recorded sound input.
