I'm looking to figure out a way to disable downclocking on my early 2008 2.4Ghz MBP down to 800Mhz making me feel like I'm on a Netbook. I refuse to pay for Coolbook since anytime I need to reformat I have to buy a new license. Is there a kext that manages speedstep I can disable? I've tried setting 2.4 manually with "sysctl -w hw.cpufrequency_min=2400000000" but it says it's read only. "sysctl hw.cpufrequency hw.cpufrequency_min hw.cpufrequency_max" gives: hw.cpufrequency: 2400000000 hw.cpufrequency_min: 2400000000 hw.cpufrequency_max: 2400000000 Any ideas or apps?
