@Hervé Good news! I added -igfxsklaskbl in the boot args in order to test with Monterey. There are no more annoying iGPU retries. YouTube works and there is transparent dock. Is my laptop spoof to HD 630?

Thanks for your speedy reply. I tried all your above recommended settings one at a time. I did not patch fbmem or stolenmem since BIOS video size is set to 64MB. As long as I have defined AAPL,ig-platform-id and device-id, the opencore verbose boot shows [iGPU] Unsupported Auxiliary ID .... followed by Doing retries #50. If I add -disablegfxfirmware in boot args under NVRAM then YouTube cannot work.

my HP 840 G3 (i7-6600U CPU, HD 520 iGPU with id 0x1916) laptop is working fine on Monterey 12.3 as MacBookPro13,1. In preparation of the coming Ventura Public Release, I genSMBIOS it to MacBookPo14,1. Since WEG v1.6.0 and above can spoof SKL to KBL from HD520 to HD620 then I have updated all kexts to the latest. It can boot into Monterey after iGPU doing retries 50 times and the dock is not transparent. Youtube can be played. But there is some performance lag on the UI. Attached are the DeviceProperties and NVRAM from config.plist I am new to frame buffer patching. Can someone please help me figure out how to spoof HD520 to HD620?

@DummyBear @robi62 Congratz on successful hackintosh HP EliteBook Folio 9470m. Is WhatsApp working on macOS 12.3 or 12.4?

Thanks for the EFI. I will stick to SMBIOS MacBookPro13,1 since that is compatible to Monterey and the coming MacOS Mammoth according to apple

I think you need to run ssdtprgen for your cpu. What is the SMBIOS? Please share your EFI for me to investigate

Both OC versions works. No diff.

@Hervé Battery indicator works more consistently on laptop SMBIOS. I choose SMBIOS MacBookPro13,1 in order for battery indicator to work. I have to revert to MacOS Monterey 12.2.1 because many apps like Whatsapp and VSCode crashed on Monterey 12.3.1 (clean installed or upgraded) with OC 0.8.0 and latest kexts. Anyway, I have updated EFI

@Hervé Thanks for your reply. I had iMac16,1 SMBIOS with @1Revenger1 ECEnabler kext as battery indicator running on HP 9470m Monterey Beta 4. Which laptop SMBIOS should I try? This ivy bridge laptop with HD4000 has been Post-Install Root Patched with OC 0.7.9

I successfully clean installed my HP9470m to Monterey 12.3.1 but apps like WhatsApp and VS Code crashed as shown below and battery management is not working. One step forward, two steps back. So, I clean installed Monterey 12.2.1 instead. Checkout Working EFI This laptop with SMBIOS iMac16,1 cannot be upgraded to Monterey 12.2.1 with OC 0.7.2. It always stuck with a prompt that “a required firmware update could not be installed” during installation. Strangely, it cannot boot up with a usb installer with OC 0.7.3 and above. After reading the successful installation of Monterey and Big Sur by @Sirsasana and @Robbish respectively on their ivy bridge desktop, I decided to tinker it by changing SMBIOS to iMac17,1 which was selected by @Sirsasana. I noticed that the latest genSMBIOS gathers macserial info from OC 0.7.9 So I updated the USB installer with OC 0.7.9 and kexts. I was delighted that it can boot as iMac17,1 with VirtualSMC.kext. My previous Monterey beta installation required FakeSMC.kext in order to boot. Rename Monterey System Volume name with Disk Utility. According to @miliuco, the workaround is to install Intel Power Gadget in order to update both the OC boot menu entry and the preboot volume with new name.

HP 840 G3 updated to MacOS Monterey 12.3 with the long awaited Universal Control. I have no brain fog after covid recovery. Checkout working EFI Altstore 1.4.9 and iPadOS 15.4 works too

Upgraded HP 9470m to Monterey beta 4 Kudos to @opencore and hackintosh107 for his upgrade to Big Sur Checkout: Working EFI for 1366x768 Broadcom WiFi Working EFI for 1600x900 Broadcom WiFi Bluetooth fixed with BlueToolFixup.kext and enable only AirPortBrcmNIC_Injector.kext

Successfully updated to Monterey Public Beta through Software Update No need -alcbeta. All works including AppleALC

HP 840 G3 100% working on Monterey. Somehow there is no AppleALC 1.6.2 kext to test. So, the workaround is to include -alcbeta in boot-args Kudos to JakeLo Checkout working EFI
