Remarkably after nearly one month I am still trying to tweak my system just so. I think this is one of the last things though, my processor preference pane. By default, the CPU controls in Mac OS X 10.5 and not enabled and in fact, can’t be enabled unless you have the developer tools installed.
The CPUPalette.app can be found in
/Library/Application Support/HWPrefs/. It’s a simple app that doesn’t allow much other than turning the processors on or off. If you click the little pill button in the top right-hand corner you can see a couple of basic preferences for window type, sampling rates and information display. It’s a quick and easy way to both monitor how your cores are being taxed and whether or not you can afford to shut a few of them down.
Your other option, if you you are already familiar with your processor usage, is to install the processor preference pane. Go to
/Developer/Extras/PreferencePanes and find
Processor.prefPane. Double click to install it. Once installed I highly suggest you click the “Show control in menu bar” for quick access. You’ll notice by installing the processor preference pane you get access to the CPUPalette.app without having to dig for it.
