Yes, 5ghz is working on both Windows 10 and macOS and both perform virtually the same according to iperf. 

I've been using the Mac setup for a few hours now without any crashes or performance drops whatsoever. I'm very happy with these results!

I'm a little confused about what you are asking. Are you trying to see what's going on in the IORegistry?

I was able to download IORegExplorer from some random GitHub repo, but you can still download it straight from Apple's dev tools.

I also have no idea what the pinout is for this particular DW1820a (CN-08PKF4) and why pins need to be disabled as opposed to the other variants.

I've been following this thread and I decided to make an account because I was able to get my CN-08PKF4 working with @Naidis' fix.

I only did the following steps based on @Hervé's solution:

1. Inject AirportBrcmFixup, BrcmFirmwareRepoData, and BrcmPatchRAM2 in C/K/O
2. Add the boot option brcmfx-driver=1 (it would not boot otherwise)
3. Inject properties (I tried injecting subsystem-id 21 as per another thread but it didn't work )
4. Taped the 3 pins on the front side and only 2 pins on the bottom just like @Naidis did.

I did not apply FixAirport or AddDTGP. I played a 10 hour loop of a fireplace on youtube to test variations of fixes, and the only one that didn't end up crashing is the method above.

Maybe you can explain what pins you masked and why.

I suggest we figure out why blocking those pins somehow fix the problem.

Edit:

Changing to brcmfx-driver=2 allows me to do Handoff
