Hello, I'm trying to get your EFI to work. I used to use syscl's distribution and recently decided to upgrade to Catalina. I've had nearly flawless success with the one provided by @maz-1 (with a few minor tweaks to get it going), but my issue with it is that once the screen turns off, it refuses to turn back on, which is does not seem like a problem with your settings based on your readme.

Unfortunately, I'm running into a few issues, both with fresh install and with trying to boot up my existing installation that was made with @maz-1's files. At first I was getting ApplePs2Controller: Notification consumer published, which can be resolved with adding SSDT-EC.aml. I was also wondering if there was a reason you didn't use EC in your SSDT or your config, how are you getting Catalina to boot without it?

Either way, I get much further after I've added SSDT-EC, but then I get stuck at IOconsoleUsers:GIOScreenLockState 3. I have not been able to figure out and have been stuck on this issue for a few days now. Is that an error you encountered? I'm using your config for HD520 as base.

I'm using an XPS 9350 with I7-6500u and HD520 iGPU, QHD+.
also using a 1 TB Intel 660p SSD and a DW1830 wifi card

Any help you can provide would be greatly appreciated!

I tried several Catalina guide for XPS 9350 included yours but no luck. Are there anything needed to tweak for specific laptop? Anyway, thank you for your hard work!

Hullo, I followed your guide. Everything works great. Thanks!
But I get random flickering from the built-in QHD monitor. I tried even with the guest accounts but it happens there as well.
What could I do to debug and improve the issue?

Thanks for your time

Can't confirm if this is the case for everyone, but I have experienced a bug many others have noticed on Catalina hackintosh

1. Handoff / Continuity with iPad iPhone etc works perfectly and is stable

bug*

Apple watch unlock is buggy and works infrequently, the cause isn't known and is documented. Not a huge deal but I'll look for a solution, I'm testing with Mojave to see if this config is the issue or the OS.

As always sleep wake would be a dream and perhaps it's related to a USB header issue on Catalina, so it's likely Bluetooth / sleep-wake are all connected

After clearing up the NVRAM, making sure the EfiVariable is not in Clover, etc. I still have the issue of screen brightness going all the way up to 100% every time I reboot. Any thoughts?

The brightness increases a noticeable bit when the charger is plugged in even though that power save setting is turned off (which makes an even more of a difference) but it should not.
Don't know if this is a MacOS thing or what.

btw, this config is absolutely amazing.
the combo jack doesn't work for me, I've had it work before on other configs(? i don't really know what to call these) when i was on mojave and high sierra. when i plug in headphones, it shows that they are indeed connected and also the audio works fine with the builtin speakers.

when i plug in my apple earbuds there is no sound, but for some reason when i plug in a pair of nicer headphones i can hear basically just a bunch of static on higher volumes that does actually match the media that i am listening to but it's just complete static.

thanks for helping!

I am attempting to boot into my install via clover, to finish the install (3rd step) but it is now stuck on:
gIOScreenLockState 3, hs 0, bs 0, now 0, am 0x0

I am using a Dell 9350 with i7 6560U with HD540 graphics and a 1080p display w/ no touch.

Any help and guidance would be really appreciated.

It might be different because i use DW1830 right now (still have DW1560 somewhere, but since it was not working years ago when I was doing Sierra/High Sierra hackintosh, I decided to change it), but the solution is to install

BrcmBluetoothInjector.kext
BrcmFirmwareData.kext
BrcmPatchRAM3.kext

from https://github.com/acidanthera/BrcmPatchRAM to EFI/Clover/Kexts/Other.

Hi, @tlefko.

I already used your repo from Mojave, and not trying your Catalina repo. And I'm using 10.15.7 (from Mac OS installer - dosguy), everything went smoothly (after multiple reboots), but I have problem with touchpad (already copy the EFI Folder from GitHub to SSD's EFI)

Touchpad not working at all, touch screen not working (while when booting installer works) - do you know how to fix it ?

Thanks

Edit : I'm using external keyboard and mouse and works great, and I'm from Mojave (not clean install) - just writing directly to Mojave installed Mac OS - maybe this is the problem ?

Has anyone been able to make the camera working? It doesn't discover any camera in the system with this EFI.

So, I was tempted to update. It rebooted to install the update and I chose "boot macOS install from Data"

and was met with something along the lines of CFG locked files. See output below. Any idea?

I am still able to boot into my 10.15.3 partition and use it normally though, so it's all good.

I add tags to files, click that tag in the sidebar but it shows up empty.

I installed based on instructions, but after I copied over EFI folder, Clover boots without the drive. I tried booting from the USB as well. Basically, Clover can't see the drive.

The drivers are all there, but obviously there is an issue because the drive doesn't show up on the USB clover.

I used the latest EFI from the repository. Let me know if anyone has any ideas.

BTW, I formatted using APFS.

Hey @tlefko I wiped my Mojave install and fresh installed Catalina using your files.
Everything works great, trackpad, brightness, sound from speakers (combojack not working though). Combojack works using the installer from Maz-1, check the sound issue thread for anyone interested.
However wake from sleep both using lid and menu, results in black screen leading to need for hard reboot.

previous releases do not have proper cpu pm set for battery, shortly releasing beta with this patched --- note this is only present on 3K model

In the current build, there's no way to patch the edid. I'll be listing the information for that below if you would like to do that, it's not entirely nessacary but is better for the 3K display

IntelGFX is not entirely patched either framebuffer wise, but will be working on that shortly.

***Notes both of these could be related to sleep, but not confirmed -- it's likely to be a usb problem

I might try Maz-1's combojack installer to see if that helps as that was needed on his Mojave install.

I remember having webcam in Mojave, but after upgrading to Catalina, Facetime just refuses to acknowledge the webcam. Might be something in IORegister, because the camera is recognised.
It doesn't show up in Hardware->Camera, but rather in Hardware->USB

The Manufacter field shows something resembling more the serial number of the Camera than the actual manufacturer. Maybe that's something that should be mapped to a different place in IORegistry?

Is there a reason for the double bt4lecontinuityfixup.kext with spelling errors?
Also maybe add NoTouchID.kext for less lag when inputting PWs if supported in Catalina.

I follow the giude to install the Catalina 10.15.7, and everything work well except audio. I try to inject layout-id but failed.

My laptop info:
cpu: i5-6200u
audio: alc-256
