eGPU not detected in Big Sur
My eGPU was playing decently nice with Catalina but is not completely unrecognized after updating to Big Sur. Rebooting either device, cycling power, nor connection work.
- It (Gigabyte RX 580 Gaming Box) is on Apple's list of officially supported eGPUs: https://support.apple.com/en-us/HT208544
- The main machine is a 13-inch, 2017 MacBook Pro with Thunderbolt 3
Again, note that everything was working an hour ago on Catalina, so hardware failures can be ruled out.
MacBook Pro 13″, macOS 11.0
