install this:

Wifi and bluetooth work just fine
If you use itlwm, you will need heliport.

If you use airportiwltm, it supports native macwifi and airdrop too.
That did the job! thanks! I went with the airportiwltm kext as works better for location and mac os overall...although not getting good speeds on 5Ghz as it seem to be an issue with the kext and not the wifi card, ethernet still getting 500 down. Also any idea how to solve the black screen after logging into the user..it reboots and then after the apple logo, opens on desktop. This and HDMI output are my only issues that i have noticed.

Can anyone on Big Sur go to:

And see if they are getting 60Hz?
EDIT: Mine seems to be stuck on 48Hz on Big Sur even after a clean install on both OC 0.6.3 and Clover 5127.
I have the 4k touch display.

If I use Clover 5122 and Catalina I get 60 Hz. If I use the same Catalina but boot with OC 0.6.3 OR Clover 5127 I am limited to 48 Hz :(

Edit: With clover I am getting 60 Hz but with Open core only 48 Hz.

Does anyone have a big Sur compatible clover file for the 7559? I know the latest clover will work with big Sur. Or has anyone gotten opencore to boot from legacy? I own two 7559s one 4k i7 and one i5 1080p I can only boot either in Catalina with clover because it only works with legacy they cannot use UEFI. I would love to make open core work as I love it on my desktop but it refuses to work legacy with my two 7559s. Thanks if anyone has any input.

Yes, Big Sur works. EFI is attached.

The screen seems to be displaying 48 Hz only though, also if you are not using UEFI you may not be able to boot using this 5127 zip file.

I suggest you use the 5122 zip file and manually upgrade your clover for LEGACY INSTALLATIONS using this guide that I followed to get clover working for Big Sur:

Greetings, I have a 7559 i7 non 4k, I would like to test Mojave and Catalina with OPENCORE and CLOVER, to see the difference. Does anyone have the OC and Clover EFI, and send it to me, please? Thank you!!

Try the folder attached in the first post of the thread. Works just fine.
For clover use the r5122 I posted above.

sorry, xrandr --props, also you need disconnect all external display.
use the python scripts in the attached file.
the output is saved into display_info.txt, the run.

python patcher.py
If able you're able to can you walk me through this? I got my edid from Linux but I do not have a display_info.txt. I cannot get the python file to open properly from Windows or mac. Can you help me convert my 4k edid? Is there a guide anywhere? Thank you so very much!!

I would really appreciate some assistance converting my EDID for my 4k 7559. OC and big sur work wonderfully on my i5 1080p 7559. On my 4k one however I get hdmi display only no internal display.
My edid is this
Screen 0: minimum 320 x 200, current 3840 x 2160, maximum 16384 x 16384
eDP-1 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
EDID:
00ffffffffffff004c834fc300000000
00190104a52213780ac585a3574f9c26
12505400000001010101010101010101
