System overview

  

 

Installation steps 

  • Assembling Razer Core X with RX580
  • Disabling System Integrity Protection (SIP) in Recovery Mode
  • Installing purge-wrangler and purge-nvda
  • Connecting eGPU with Macbook Pro via Thunderbolt cable and Adapter
  • Optional:  disabling Nvidia dGPU via EFI boot alteration described in post by Gaerraty. It helps with overall power management and temperature of the system since after applying purge-nvda dGPU (Nvidia GT650M) continues to use power unless disabled during the boot of the system.

Comments 

  • It is a great setup, special thanks to Mac_editor, Gaerraty and Clarketus for their guides and posts
  • The purge-nvda script can be uninstalled when not used with eGPU and installed again via terminal menu
  • Hot plug/unplug of the eGPU is working alright
  • Sleep mode and brightness control of internal display does not work
  • Internal display does not switch off in clamshell mode, but if the system is sent to the sleep from menu, then internal display switches off after a short time and it is possible to work on external display connected to eGPU
