[Cyberdevs]

If you get the Unknown CPU in About This Mac you can use the following settings according to your processor.

Use IORegistry Explorer or IOJones to check the current "cpu-type" value for your processors. You can find the value by clicking the CPU0@0 like shown in the picture below:

I have an Intel Core i7 6700K so the value is 0507.



For Core i3 Series you can set the CPU type to:
0x0309 = Core i3

For Core i5 series you can set the CPU type to:

0x0407
0x0601 or 0x0605 (to be more accurate) = Intel Core i5

​

For Core i7 Series you can set the CPU type to:

0x0701 or 0x0705 (to be more accurate) = Intel Core i7
You can also try 0x0507 if the values above didn't work.

For Xeon Series you can set the CPU type to:
0x0505 Dual-Core Intel Xeon
0x0510 Quad-Core Intel Xeon
0x05A5 Quad-Core Intel Xeon
Intel 5960X 8-Core Intel Xeon E5 0x0a01 (Thanks to nmano)
