Hi everyone,
I tried to clean install Monterey but both no luck. Firstly I updated my EFI to 0.7.5, tested it on big sur, everything worked just fine. Then I tried OTA update, that kind of worked, but in the end it showed some short purple horizontal lines up on my display, stayed like that for few mins and than my monitor just turned off because of no signal but PC kept running. So I tried wiping NVRAM, same result. So I went back to Big Sur, everything works fine. Now I’m trying clean install but same purple lines and after few mins black screen.
My specs are: MB: MSI 270 SLI plus CPU: i7 7700k GPU: RX470 I use airport card so I have no BT or WiFi kexts
