Hi sorry for late reply Efi was done with help of baio77 and then I changed a few things myself

12.3.1 it was

Thats strange I will have to investigate It would be interesting to try your efi

hi it did....

yes here is my efi EFI840g1.zip

Ok thanks Ill try that Took me ages to write it in config properly Thanks for help Mark it as solved Hervè

hi I finally managed to boot with Monterey with my hp revolve . Everything seems to work fine except the touch screen. I used first kext that where working in bsur then I updated them but result is the same . Don't know what to do I enclose my config file and my IOReg file, maybe someone can tell me which kext I should need Thanks guys macbook pro.zip config 3.plist.zip

Good old clover still working good Powermanagment working like a beauty. Could not get that with OC Monterey 12.3.1 just did a fresh install with chris111 clover package @yahgoo I enclose my EFI Folder just in case you want to have a look EFI.zip

here are my files MacBook Pro.zip EFI-640g1mn.zip Haswell platform

Easy if you know how is not only the kexts that would be easy is the config the difficult part

Hi I have a 640 g1 which in bigsur works ok but all efi I tried for monterey no joy it doesn t boot As soon at it start after welcome screen when I choose disk it reboots ... The only thing I can think of is something wrong in my bios setup?? But works with bigsur....

Thanks Herve' I keep that in mind.

hum it seems that MacBook Pro 12.1 is not good according to this

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

@yahgoo hi whatsup is working fine for me on my 9470m on 12.31 That is with Chris111 efi and files what drive me crazy is the fan always on all the time and frequencies always @1.7 I tried all the tricks but no luck with Mojave powermanagment works like a beauty with only xcpm but any os above not too good. It's a shame coz is a nice laptop....but Mojave a bit old...

ok thank you

the efi is still 0.79 not 80????

hi did you generate it with ssdtime or you have used a prebuilt?? Do you frequencies go down to 800??? omg Jake Lo you are the best I just changed SMBIOS to 11.4 just used ssd-plug.aml and its great

Hi I was hoping you would reply as you have a dell same specs as mine. The only reason I put all them to see if they where working What do you use for your dell???

Hi guys I have an elite book 840 g1 which works beautifully on bigsur but on Monterey frequencies don't go lower than 1200. I have cpufriend and also I put ssd-pm.aml in acpi in OpenCore to get all frequencies but Monterey does not won't to obey them... Can someone with more knowledge enlighten me in the proper procedure to achieve it?? No idea what files you need from me I enclose my efi folder The photos is from bigsur you can see its working fine EFI840monte.zip

ok so if first patch don't work I need to try con2 or con 3???? Thanks Hervé Edit: Great it was con1 Mark post as closed Thank you

hi I have had success with OpenCore on the above mentioned laptop but with all the efi I tried I don't get hdmi sound??? Jake I tried your pack to but same result no option to select sound from tv from sound preferences . What can it be??? I enclose efi that I use which to my surprise I can boot to window 10 too no acpi errors efibootwin.zip

I would like to thank you all for the efforts for trying to help me It seems that after Mojave fans seems to be on constantly I tried with Catalina and managed to get fans working in bigsur but not happy with fans mostly on all the time. My other laptopsHP 840G1 and HP 440 G4 behave very well so it looks like either I stick to Mojave or I sell this particular laptop Thank you guys for the help anyway

@Baio77 won't even boot too many acpi errors. @Jake Lo no change still no battery.

Can you extract the right battery patch from DSDT from bigsur? This way I can test it with my fan working EFi because I use that DSDT I loose the fan Just want to see with the right patch for battery if it appears I have been trying my self but then I get erro when I try to save it
