yahgoo Posted April 14, 2022 Author Share Posted April 14, 2022 I think you need to run ssdtprgen for your cpu. What is the SMBIOS? Please share your EFI for me to investigate Link to comment Share on other sites More sharing options...
robi62 Posted April 14, 2022 Share Posted April 14, 2022 Hi smbios is MacBook Pro 12.1 I tried with what Herve suggested but still the same. now I have tried MacBook Air 5.2 because my cpu is exactly like it. Intel(R) Core(TM) i5-3427U CPU @ 1.80GHz The problem is both cpumanagment kext and x86 platform plugin are running If I disable cpumanagment kext then frequency is only 1,7 with both minimum frequency also the same but I get turbo frequencies . I also tried with cpufriend and combinations like Jakelo suggested but no joy. In Mojave with clover and plugin 1 enable works very well. Here is the EFi Im using EFI.zip Link to comment Share on other sites More sharing options...

Administrators Hervé Posted April 15, 2022 Administrators Share Posted April 15, 2022 No, as stated before, you need the SMBIOS of an Ivy Bridge model to obtain proper power management on an Ivy Bridge laptop. You may only use the MBP of a more recent model such as Broadwell MBP12,1 at initial installation (not mandatory thanks to -no_compat_check boot arg) and update (mandatory unless you apply tricks to your SMBIOS) for compatibility reasons with Monterey. Given the likely trouble you're likely to experience, I recommend sticking to Big Sur, the last macOS version too fully and natively support HD4000 graphics.

yahgoo Posted April 18, 2022 Author Share Posted April 18, 2022 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 Link to comment Share on other sites More sharing options...
