Disable Speedstep / Disable downclocking / Coolbook alternative ?

[pooprscooper]

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?

So you want to rip the engine out of your Ferrari and replace it with one from an electric scooter...why, exactly?

Other way round, dude. And why do people feel the need to post entirely useless answers like that anyway?

OP, no idea I'm afraid. Can you change the permissions on that file to make it writeable?

Put "sudo" in front of your command and it'll do what you want, I imagine.

Just be careful with sudo... if you don't know already, it drops that command into super user mode, which can have disastrous consequences if you've got the wrong command.

I used sudo and it still says it's read only.
