MacOS reports from the eGPU menu bar icon that there is no eGPU connected when the Razer Core X eGPU enclosure is connected to my MacBook. Turns out the my external GPU that’s powered by the Sapphire Pulse Radeon RX 5700 XT isn’t working properly.Īt first, I thought it was a hardware failure. When I turned on my MacBook today, I was surprised with a blank display on my external display.
