Compatibility Issues - Unknown CPU model 0x3c

Thought of giving a go at installing Yosemite on my recently built PC, but I'm getting the error:

this is an unknown CPU model 0x3c.

Click to expand...

My CPU: Intel i5-4690K

Is it not supported? Could this be caused by anything else or it's CPU for sure? Anything I could try?

I've tried -x graphicsenabled=no, but no success.

I have the similar cpu on a Gigabyte board Z77N Wifi with same problem "Unknown CPU model 0x3c." Make sure your bios for one has the following turned off: CPU Virtualization and VT-D disabled. The second step to was to give it a definition of a iMac 14,1 to get it working. Best of luck in your build. Share what works for you...

I give my thanks and support to MacMan, Toleda, and Rehabman the moderators and developers of a great site! ~ cdman
