On my Powerbook Titanium 1ghz, I have been running into one issue over and over. While System Profiler and other Apple system tools report my CPU as a 1ghz processor, the terminal command "sysctl hw.cpufrequency" shows it as running at 667mhz. Someone with an 800mhz TiBook also gets a return of 667mhz when he runs this command. Do you think this could be an issue as to how other programs run on the computer? The Unix command SHOULD return the value that the computer is running at, more so than System Profiler, which is basically pre-programed by Apple.
