Product Description:

This is for diagnostic purposes. These scripts run a Terminal shell script (sysctl hw.cpufrequency) to determine at what speed your processor is actually running the maximum speed your processor is currently capable of running. If the number displayed is significantly lower than what it should be according to your chip speed, your Power Manager has most likely gone wonky and you need to reset it. Shut down your computer. Hold down SHIFT+CTRL+OPTION+POWER for 5 seconds, then start up again. Run this script again to see the improvements! WARNING: This will reset your preferences (clock, etc) to their defaults and erase any RAM disks you may have.

  • Mac OS X 10.3

CPUfrequency Scripts Troubleshooting Reportsysctl hw.cpufrequency does work for this script... - Version: 1.0, 11/19/2003 05:42AM PST

So, the CPUfrequency scripts work fine for what they are meant to do, which is simply to report the maximum possible number (speed in hertz) your computer currently thinks in the processor is capable of achieving. If it reports back 5333333334 and you have an 867mhz chip, as happened with me earlier this week, then your PMU needs to be reset, so that the computer will realize that there is more processing power available there, should it be needed... Thanks, Sarah, I'll make the changes to the script's output and repost it here as version, 1.1! Mozart111, did your clock reset on starting the computer back up? If not, then the PMU probably wasn't reset correctly... Here's the link to the Apple Knowledgebase Article that explains in more detail how to do this. -C.K.

This little adjustment to the script will make it look a little better:

display dialog "Processor Speed: " & (round ((do shell script "sysctl hw.cpufrequency | sed 's/^hw.cpufrequency: //'")) / 1000000) & " MHz"
