18.) About This Mac

I have a Intel® Q6600 CPU. This CPU is not known by Mac OS X. In the "About This Mac" panel a unknown cpu is shown. If you find this annoying you can change this easily by editing one file. It's only a cosmetic issue and absolutely not necessary. Edit the file /System/Library/CoreServices/Resources/English.lproj/AppleSystemInfo.strings as root (use sudo) and replace the "Unknown" for "UnknownCPUKind" with the string you wanna have displayed in the About panel. You must do that for each language you are using (English.lproj). If you don't know which CPU you are using type the following in terminal:

> sysctl -n machdep.cpu.brand_string

I changed "UnknownCPUKind" = "Unknown" to "UnknownCPUKind" = "Intel Core 2 Quad Q6600" and know I have this "About This Mac" panel:
