egpu not working on macOS catalina
laptop model: 2017 13-inch MacBook Pro with Touch Bar
OS: macOS catalina 10.15 beta 2
After I installed the graphic card to egpu box and connected it to my laptop, nothing popped out, no notification, no menu bar, no nothing, I can neither see it the "About this Mac" nor GPU History in activity monitor.
But the fan on GPU is running, and I can see it in the Graphics/Display section in system report:
Type: External GPU
PCIe Lane Width: x4
Vendor: AMD (0x1002)
Device ID: 0x6fdf
Revision ID: 0x00ef
and also when I unplugged the egpu, an alert showed up saying "GPU not disconnected properly". I also tried purge-wrangler.sh but no luck.
So I guess I'm half way there. Does anymore have any clue or suggestion?
