macOS eGPU Info

Official Thunderbolt-connected external graphics card support for the eGPU Breakaway Puck Radeon RX 5500 XT and eGPU Breakaway Puck Radeon RX 5700 is limited to macOS Catalina 10.15.7 (and greater) and Thunderbolt 3 equipped Macs. See the PDF for compatibility details.

Technical Notes

  • Apple notebooks with 45-60W AC power adapters may be powered and charged by the eGPU Breakaway Puck, even while gaming. Apple notebooks with AC power adapters rated at 85-100W will accept 60W power from the Puck but will slowly discharge. Connecting bus-powered storage to a laptop will draw additional power that may affect the charging (discharging) rate. When sleeping, any connected computer that supports Thunderbolt 3 charging will be charged to 100% by the Puck.
  • Support for four 4K monitors requires a Sonnet Thunderbolt Dual HDMI 2.0 Adapter or Thunderbolt Dual DisplayPort Adapter (both sold separately).
  • Ultimate gaming performance is attained by using a display attached to eGPU.
