No, just tested it and watched a 2 minute video. Maybe my power play tables are too aggressive? I do have my Vega64 of Water. Try this config. I removed the power play tables. Rename it to config and replace the one in your OC folder.
Since you've made it this far. You might as well change your login background.

Don't forget to create another snapshot
sudo bless --folder ~/Desktop/Logo/back/System/Library/CoreServices --bootefi --create-snapshot
I finally moved over to Big Sur yesterday. I was a bit surprised when the old path of replacing the system logo didn't work. Took me a bit to figure out how to get it to work, but here we are.
Process I took.
First you'll have to disable secure boot.
Boot into Recovery.
Big Sur OS Logo.
Apple has changed how the OS is locked down. Very complicated process to make any changes now. I've got it figured out after having to restore the OS once :lol: Making a tutorial and plan on publishing it on the Big Sur portion of this forum.
Opencore updated to 0.6.3 to support Big Sur in the first post. I've updated and can confirm wifi/bluetooth, etc work. Replacing Assets didn't work with my script. I'll look into to this and try it manually again.
If you are using the opencore from my other thread, then you'll have to update ROM.
"OPENCORE: You must add your mac address as the ROM in order to get your Messages working."
If you are using Clover, make sure your onboard network card isn't disabled in bios.
Install your RX580. Intel's iGpu should really only be used for troubleshooting if your Discreet GPU is having issues. If you wanted your computer to be slow you wouldn't have built a hackintosh ;)
Also, boot with OpenCore. I stopped supporting Clover as I feel it's the past.
NOTE: Supplemental update 10.15.6
Before installing, remove EFI-Backups in the root of your drive. The update refused to install, but it also destroyed my ability to boot regularly. I ended up hitting Command+R while selecting my boot disk with the mouse in the OC menu to get into recovery mode...
Not sure why you would have lost sound. Mine is still good. As a precaution, I've updated the first post with the latest OC and kexts. Make sure after you install it to reset your NVRAM and set your ROM (Ethernet Mac Address).
