According to here, your card should be supported. OC 0.7.0 will work on Big Sur.

CPUFriend*= For optimizing performance. You can't use the one I have since it's make for the specific CPU Sinetek-rtsx= SD Card reader, my new pack uses a new kext by FireWolf, better performance verb-stub= For combo jack, need to be combine with the script included in my guide Looks like you'll need to change the smbios as well to MBP14,3 When you do that you'll also need to update the USBPorts_5510 kext info.plist to MBP14,3 as well otherwise the kext won't work since it's hardcoded to MBP13,3 I had made all those changes in my bootpack above, FYI

Give this bootpack a try, not sure if the usb ports are all working for you system, you'll have to check them then Post new IOReg file what wireless card you have? Precision 5520 OC 0.7.5.zip

DW1820A is supported, NOT DW1820, they are not the same card. DW1560 and DW1830 remains working but not Bluetooth. You don't have graphics acceleration, let's try to get that work. The freezing is also contributed by FakePCIID*, just disable them all. Seems it's not longer need for HDMI audio.

disable BluetoothInjector kext after booting post IOREg using v2.1 as I stated above

check the bios, make sure there's no other OC boot option. Create one only to point to /EFI/OC/opencore.efi

You'll need to replace the PM981a

Your NVMe PM981a NVMe Sams (238G) is NOT supported

Post IOReg file using IORegistryExplorer.app v2.1 only

Welcome to OSXL! 1st thing would be to post the system's full spec. Then let use know what version of MacOS re you trying to install Specs needed: CPU Audio Codec Touchpad type Wifi / BT model Ethernet SD card reader if there's one Display full resolution BIOS version If you have Windows install, probably easiest it to post the output of dxdiag.exe

does sleep / wake for your system?

If you have BlueInjector kext enabled, make sure to disable it. Both Broadcom or Intel BT injector, replace it with BlueToolFixup.kext Also make sure you upgraded to OC 0.7.4+

is this ioreg pulled from using this bootpack? the one I posted a page back? Not seeing SD card reader loaded so it means it might not be booting from that bootpack with SecureBootModel disabled

You didn't post what I requested

It has an Alps PS2 touchpad version 8, there's no support for it that I know besides Dr. Hurts's voodoops2Controller with minimum functions and not very smooth. SkyrilHD has a version out with gestures but only supports version 7

Disabling BrcmBluetoothInjector.kext should fix it for Monterey or add the MaxKernel = 20.9.9 to if you're dual booting with Big Sur and below.

could be a hard disk issue, MacOS unsupported

DW1550 is what I have for my Dell Haswell laptop, bluetooth is still a no good though

moved change OSID to XSID (to avoid match against _OSI XOSI patch) before change _OSI to XOSI disable change GFX0 to IGPU

By adding the Boot option, does it boot to the OC picker? Where does the issue start?

Following the link from Hervé and making the changes, I was able to get 3 displays working as well on my 7040 and no issue with turning on and off monitors. Give this a try config.plist.zip

go to the bios, add new boot Option Name it OC or OpenCore or MacOS, whatever you like Point it to /EFI/OC/OpenCore.efi. Move it to the top of the list Save and reboot

try add to boot-args igfxonln=1

try this, updated to oc 0.7.5 5580_HD620_OC0.7.5.zip

Try replacing with this ssdt from brightness SSDT-BRT6.aml.zip
