device-id is wrong 191B8086 should be 1B190000 AAPL,ig-platform-id is wrong as well 191B0006 should be 00001B19 or 06001B19

Please post your system's full specs + Ioreg file using IORegistryExplorer.app v2.1

I purposely removed the internal port for the smart card reader since it'll never be supported, waste for energy. If you want it, you can re-added. I think it's port HS07 or HS08, set connector type to 255 for internal, or use the one from my earlier bootpack.

what issue with the Ports?

Replace BrcmBluetoothInjector.kext with BlueToolFixup.kext. But it might still not work in Monterey, just have to wait for further development. See here

Yes, BT is not fully supported yet. Make sure you don't use IntelBlueToothInjector, but rather replace it with BlueToolFixup.kext instead.

change keepsyms=1 alcid=3 to keepsyms=1 alcid=11 If still no audio, try patching IRQ Please post IOReg file

Looks like you might have a mismatch of Config.plist and OC boot/drivers Your bootx64.efi is dated 10/4/2021 Opencore.efi is dated 7/7/2021 Tools folder are dated 11/2/2020 Drivers folder has mixed dates Surprise you could get this running in Big Sur without issue. Here, updated your files. EFI_OC0.7.4.zip

if you have read further down, you'll see that you'll have to set the DVMT. https://osxlatitude.com/forums/topic/14372-solved-dell-7370-m5-6y57-cpu-cant-upgrade-from-mojave-to-big-sur/?do=findComment&comment=104738

@angelts How did you manage to get the trackpoint and mouse keys to work?

according to the IOReg file you have device-id set to 1b190000, should change it to 12190000 Looks like you're connected to Con1 so make sure to add the frame buffer patches you posted on the 1st post.

Try the latest version, I think it's 2.0

I'm asuming you fixed the audio and HDMI issue which means you had made some changes Please post latest EFI plus IOReg file

Please post full system's spec and add it to your signature file Information we'll need: CPU Audio Codec Touchpad type Wifi Ethernet SSD / NVMe Which Mac OS you're trying to install? These are info we need to get started

How many external display ports does it have? DP, VGA or HDMI

Update OC to 0.7.4, update all the kexts Change USBPorts_E7440.kext info.plist to reflect MBP11,4 That should do it

switch it to MBP11,4

ok try this one, mirroring the one that works config.plist.zip

Use this Config Post new IOReg after whether it works or not config.plist.zip

Not seeing any external display connected according to the IOReg file. Do you have it connected when you save the IOReg file?

only image I recommend is from Olarila's website. His image will extract to the USB which also include the EFI file but you should replace that with the one here for this specific model. Don't know if the one you download is vanilla or not

Try bootpack from here https://osxlatitude.com/forums/topic/16366-latitude-e5570-help-required-to-install-big-sur/?do=findComment&comment=112039

can you post IOReg file with the DP monitor connected? use IOregistryExplorer.app v2.1 please

post IOReg file to determine if Bluetooth is picked up
