yahgoo Posted April 6, 2022 Share Posted April 6, 2022 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.

Administrators Hervé Posted April 6, 2022 Administrators Share Posted April 6, 2022 This an Ivy Bridge laptop, isn't it? If you use an SMBIOS different from MBP9.x, MBP10.x or MBA5.x, you won't have CPU power management working and are therefore likely to experience such issues as degraded performance and/or increased heat. Whatsapp and VS Code crashing -> could be linked to issues with Metal (remember that Monterey has no native support for HD4000 unlike Big Sur). As for battery management, well... I'm not sure it can work with the SMBIOS of a desktop but you'll sure need to inject a battery management kext. Link to comment Share on other sites More sharing options...
yahgoo Posted April 6, 2022 Author Share Posted April 6, 2022 @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 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 6, 2022 Administrators Share Posted April 6, 2022 As stated above, you should be using the SMBIOS of a MBP9,2 or MBP10,2; this will require to add boot arg -no_compat_check and will block all future updates OTA. For Monterey updates, you'd have to switch back to the SMBIOS of a supported model (the iMac SMBIOS you currently use or MBP11,4/5, MBP12,1, etc.).

yahgoo Posted April 9, 2022 Author Share Posted April 9, 2022 @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 Link to comment Share on other sites More sharing options...
