@Sniki
Thanks for your incredible work!

My laptop is T440p with i7. Almost the same as your test machine. I try to install macOS 10.13.2.
Because I don't have brm wifi/blue. I installed kexts except Broadcom_Wifi.kext BrcmPatchRam2.kext BrcmFirmwareRepo.kext.
I use the config.plist and SSDT file you provide. But it stuck when boot. It shows black screen and what shows below.

I can use @RehabMan config.plist (HD4600) and choose drop SSDT-t440p to boot. So I collect other problem reporting files.
Hoping your reply. Feel free to PM if you need any more information. Thanks!

Might be due to dual GPU.
There is no code in SSDT-T440P.aml to disable the Nvidia.

tried to boot step by step though each id (with inject EDID enable),
from id number 1 to number 13 I got same result System restart
the id number 14 0x0d220003 system stop (forever) screen at here(should be restart in others ID)


then I tried boot with id 14 and change inject EDID = false
=> WOW, I reach Desktop with transparent effect, and check system info, Intel HD 4600 1.5GB already
everythink very smooth.



but It seems not complete full performance,
because only 24bit color in detail info

still having something wrong with inject EDID, right?

I also get message warning everytime I login to Desktop









I would like to thankyou RehabMan very very much, for your support

There are other people who really deserve help unlike you. You just let others do your stuff.

have you tried my ig device id? also what display is built into ur laptop? you probably need to flash mod BIOS - and this is not possible on our glorious lenovo shitdevices so u need a flash chip.

ps. FakeID 04128086 should do no difference without ig-device-id. just try a config where you have FakeID 04128086 and ig-device-id 0x0d220003 .... i cant boot with 0x0a26006 or whatever the device id is too so for me the fix was that damn 0x0d220003 framebuffer. again im by no means any expert about that **** but it worked for me lol

No idea why that is the case. Compare detected EDID in working ioreg vs. Clover detected EDID in bootlog.

Endless spamming of this thread is not helpful.
Clearly, your laptop is different from others here in that it uses eDP, which is not well supported.
You should at least open a separate thread.

Of course you need another pc/laptop to do so.

Send the dump to bios mods forum and ask someone to remove whitelist for you.
Someone will respond and send you the link with your modified bios.
You download the modified bios and then:
First of all you erase the eeprom(bios chip)
Then you write the modified bios to the eeprom (bios chip).
Re-assemble the laptop and you should be able to boot just fine.

hey,

somehow I bricked my Bios, but i got new one and lucky I got the bios without Wifi whitelist.
I bought dell dw1830, the wifi is working but no bluetooth.
I made some changes in the sddt,(from your L440 guid) because I get a IMEI error on boot but the error is still there.
and I cannot change the country code to Germany. I change the patch for "DE" but it still show US.

thx
