Installer-dev mailing list (Installer-dev@lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/installer-dev/site_archiver%40lists.a... I've been detecting CPU speed in my InstallationCheck scripts using `sysctl -n hw.cpufrequency` and `sysctl -n hw.cpufrequency_max` These are returning the correct values on most machines, but the wrong values on other machines (at least 867MHz G4 PowerBooks in 10.3.9) -- So some of our customers get a confusing message about their CPU being too slow. Is there a way to accurately detect the maximum cpu speed on all OS X Macs? Or at least on the ones I need to support (G4, G5, x86 -- 10.3.9 and later)?
