An app for Mac OS X with a minimalistic UI which lets you quickly throttle down the CPU usage of any of the running processes.
Now added save support (AppPolice remembers your throttling choices)
Credit goes to fuyu for the original code.
The project requires a dependancy ChromeMenu.Framework. Clone both AppPolice and ChromeMenu into the same directory.
An app requires OS X Lion 10.7 and up.
