Hi, I have a RX580 eGPU with a 2015 iMac(T2), and everything was working fine in macOS until a day ago. I wanted to try to trouble-shoot error code 12 again, but when I restarted, the eGPU didn't activate, and wasn't available in device manager. I thought this was just a windows/macOS Catalina issues, but when I booted back into macOS, it still didn't activate. I tried reinstalling purge-wrangler, but it didn't do anything. Is this a fault enclosure? If so or if not please help.
