Mac Users And System Noise

I just recently bought a Presonus Firebox and noticed a lot of noise coming from my powerbook G4. Opening a program, moving the mouse, almost anything caused a noise from the system.

You need to download CHUD tools from Apple.

Go to System Preferences->Processor and Disable NAP mode.

Problem solved! But at the expense of extra CPU heat.

I’m sure people using other interfaces have experienced this.
