Hi
I have compile errors with a Gigabyte H61N-USB3 Bios F8/Pentium G2020 IveBidge (log below) or a Gigabyte GA-H67MA-UD2H-B3 Bios F8/Core i3-2105 SandyBridge

Log below is with the G2020 and -d 2 option, ACPI folder content attached.

What's wrong ?
Thanks

Up. No idea ?

I saw other people having the same issue but found no solution.

There might be a good reason why this script generate these errors

Thanks

Pentium processors are unsupported, Apple do not use them in their builds.

OK.

But I have the same issue with my two CPUs : Gigabyte H61N-USB3 Bios F8/Pentium G2020 IveBidge (log below) or a Gigabyte GA-H67MA-UD2H-B3 Bios F8/Core i3-2105 SandyBridge

Moreover there is the -p command line option that allow to force the type of CPU, no ?

hi I am using the same CPU but my frequency staying always between 2.5-4.2 even on idle, I have used the open core boot loader so have you done any power management SSDTs using cpufriendfriend if you can share or even the SSDTs so I can check as what I missing

Good afternoon, thank you all in advance! well I'm having trouble getting my CPU to work! I can't get the states at all. I've already added several ssdt to my CPU, but nothing solves! some help!? i am trying to use the ssdt i5 OC.
best regards

Pls beware, this doesn't work anymore, after step 3 it aborts.

Easiest way for Ivy is to ignore ssdtPRgen.sh entirely...

Instead:
- delete SSDT.aml if you already created it
- set config.plist/KernelAndKextPatches/KernelXCPM=true
- set config.plist/ACPI/SSDT/Generate/PluginType=true
- make sure you're not dropping OEM CPU SSDTs (eg. DropOem=false, no CPU SSDTs identified in DropTables)

Would this work for Ivy Bridge - EP? I got a Sierra 10.12.6 install on a Sabertooth X79 with Xeon E5 1680 v2.

Please help I get this Warning: No ACPI Processor declarations found in the DSDT! Using assumed Scope (\_SB) {}
I'm using macpro 6.1 smbios please help geekbench 4790 multicore but working great

Is there a particular reason why IGPU pstates could be missing however CPU PM works fine? (i7-5775c, iris 6200 pro, clover, WEG, imac 16,2). Everything works but the gpu is stuck @300mhz. Tried all sorts of options, acpi patches, injections methods, igfxrpsc=1 in weg, nothing seems to work..
