Greetings, I had some problems with that EFI
When I boot with HDMI plugged, my laptop screen goes blanc.
The OC boots creen resolution goes too big
I'm using Bios 1.2.4, and tested 2.9, 3.0 and 3.1
I have some UEFI and Legacy issues, sometimes boots, sometimes does not.
My 7559 is i7 non 4k.
Thanks

In time, Bios 1.3.1.
I have to boot, change do Legacy, then reboot and change do UEFI (without legacy), after that the system boots ok.
Hi. What could cause this? I have a friend who needs to do the same on his Dell 7559...

I kinda got it working now, using legacy boot instead of UEFI, but instead of going straight to the Opencore menu it takes me to this menu instead:

I have to go into boot manager and pick the efi boot file manually.

Did anyone else have this problem?
Same here, did you resolved it?

Thank you all! I finished move to OpenCore and BigSur.
At the moment, fixed all issues actual for me except 4k@48Hz.
This config is a compilation of the config from the first post and @slipanot config
What is added or changed:
1. alcid = 16 - need to work 2.1 speaker with subwoofer
2. alc-verb_jack_fix or ALCPlugFix-Swift - two methods for fix hotplug headphones jack
3. enabled SSD trim by deafult
4. changing igpu device property (4k@60Hz on Catalina, 4k@48Hz on Big Sur, HDMI, 2048Mb VRAM)
5. SSDT-DGPU.aml - Nvidia dGPU off
6. SSDT-BTNB.aml - Backlight fn buttons work together with patch:
change Method _Q80 to XQ80, pair with SSDT-BTNB.aml
change Method _Q81 to XQ81, pair with SSDT-BTNB.aml
7. Using MacBookPro13,2 (required for working HDMI and Big Sur correctly and smoothly (BigSur had a lot of lags with MacBookPro13,3)

Not used and not tested by me:
1. Built-in card reader (before I used Sinetek-rtsx.kext but stability and speed did not suit me)
3. DRM on Safari

Also I disabled SMCDellSensors.kext as it causes sound lags for me.

If you have Secure Boot Violation error read this post:
I tried to install Big Sur after some time the display go black and I need to shut down.
any suggestions

Greetings,
I've tried CLOVER and OC, both didn't boot as UEFI (LEGACY ENABLED AND DISABLED EITHER).
Just boot as LEGACY.
Bios 124
Thank you!

I did it. I can't check hdmi, but most likely it should work, and most importantly, I got 4k@60Hz in BigSur. As a result, it remains to solve a few small problems with sleep and getting out of sleep and the config will be completed.
