[Success] Big Sur 11.5.2 - MSI Z270-A Pro - Intel Core i7-7700 - Gigabyte RX 580 8GB

First of all, I would like to thank all of the community, developers and people who share their knowledge and experience. I had couple of experiences with Clover on High Sierra but there were some issues with my builds and I thought I should give an Open Core try.

I read the official guide start to finish:

Dortania

and followed the guide here:

I built the system and boom! it was success in the first try! I couldn't believe how smooth the whole process was. My LAN, Soundcard and Video was ready to go on the first boot. The documentation is very detailed and video guide helped a lot too.

After completing the installation I found that my USB3 drives are not recognized. Somehow my USBmap.kext was wrong and I fixed it by following this guide:

After that, I plug my Windows 10 hdd and there was a blue screen (0xc000000d) indicating that I should repair my drive. Before going on with repair or anything, I quickly go back to guide and found what was wrong. Enabled SyncRuntimePermissions on config.plist and then Windows boot was smooth as well.
Finally, when I load 4K videos and encoding on iMovie, cpu fan was kicking off. I quickly figured that radeon video decoder was not on.
I applied overrides below and video decoding and encoding was ok too.

So only thing that does not work is wifi. I knew that it won't work but interestingly Mac system info shows wifi card info but it's obviously not working.

I'm attaching my EFI if anyone needed.

Cheers!

Hi guys,

Just to quick update here. Machine is running fantastic, however, there is still an issue that I was having since High Sierra built; mouse lag.
I tried to use different mouse hardware and right now I'm sure it's not related to mouse or bluetooth or USB port settings.
I tried switching from HDMI to dvi and it was smooth for a while. But after couple of restarts it was back to its initial state again.
What I gather from I read so far is, it seems like there is something wrong with RX 580 frame buffer, but I don't know how to fix it. If there is someone who has the solution please help me on that.

All the best
