ShhMBP is a fix for the MacBook Pro noise issue using a StartupItem that loads a kernel extension which disables the C4 power mode on the CPU. It is packaged in a standard Mac OS X installer to make installation easy.

Do NOT install this on computers other than the first generation MacBook Pro.

This software is unsupported and comes with absolutely no warranty.
