So I'm almost there. Before starting, I upgraded Clover to 5070 and installed Lilu and WhateverGreen. I then had to add SSDT-EC to fix the "stuck at the Apple logo" issue during the upgrade, but after that it completed. Sound works immediately, but neither the WiFi or Bluetooth are working. Wired ethernet is working. The Radeon 5700 XT (new last week, and the primary reason for the upgrade) is NOT working right.
Wifi: I installed the InsanelyMac Atheros driver, but no success. My card is FV-K1200AC BT. Using the InsanelyMac driver was a stab in the dark but I was hoping. It does not appear in the system profiler.
Bluetooth: Besides the Fenvi card, I also have an IOGEAR GBU521. Neither appear in the system profiler.
Graphics: it appears as an AMD (0x1002) 0x731f, rev 0x00c1 with no Kext loaded. It shows a resolution of 1920x1080 (1080p FHD) in the profiler. The pointer leaves trails, and anything that needs hardware acceleration doesn't work either (including Opera). I may go back to the 580 unless there's a better answer.
Any ideas? Thanks!
