How to modify/change the 'About This Mac' dialog

[Puttabong]

Always wanted to get rid of the Unknown Processor, which is showing in your 'About This Mac' dialog?

Simply open the Finder, then press CMD + N to open a new window.
Now, navigate to:

/System/Library/CoreServices/loginwindow.app/Contents/Resources/YOURLANGUAGE.lproj

Replace YOURLANGUAGE with the language file which is in use, in my case: German.lproj

Then use Nano/TextMate/SubEthaEdit or your favourite text application to open the AboutThisMac.strings file!

Now search for this:

"ABOUT_BOX_SINGLE_PROCESSOR_FIELD_FORMAT" = "Customize This To Your Liking";

or

"ABOUT_BOX_MULTIPLE_PROCESSOR_FIELD_FORMAT" = "Customize This To Your Liking";

Now enjoy your customized dialog.
