Unknown CPU model 0x3a

Hey!

 

I'm getting this message everytime I boot into OS X in verbose mode:

 

kernel[0]: WARNING: IOPlatformPluginUtil : getCPUIDInfo: this is an unknown CPU model 0x3a
kernel[0]: -- power management may be incomplete or unsupported

 

I run Mountain Lion GM on

CPU: i5-3570K

Mainboard: Gigabyte GA-Z77X-UD5H

Model: MacMini5,1

 

It doesn't seem to affect my system, which runs quite smoothly (although it panic'd once or twice). Anyway, I'm a little confused about that message. I googled it a lot but couldn't find any help ..

 

Does anyone have the same problem / know how to get rid of it?

Respectively can someone tell me more about this issue?

well nope, the model identifier wasn't it .. I even tried some MacbookAir / Pro models

 

I have the same ivy bridge CPU, the error code you are getting is because there's no smbios available for Ivy Bridge yet. I haven't experienced any problem using 10.7.4 or 10.8 with this error code. I'd wait until a new smbios is released but don't worry, performance is not affected.

I'm having the same error shown while booting. OSX boots fine, but I'd like to have as less errors as possible. Is there a way to fix this with DSDT patch or something else? My mainboard is ASRock Z77 Extreme4 with Core i5-3570k. OSX is Yosemite. Bootloader is latest Chameleon. Graphics is nVidia GTX650.

Make sure you're using an smbios that supports ivy bridge. Either that or just ignore the error.
