Paul,

use sysctl() not sysctlbyname() as syscntrlbyname() seems to be broken as in the results I get on Leopard 10.5.2:

sysctl:

-------------------------------------------

CTL_HW, HW_MACHINE: i386

CTL_HW, HW_MODEL: MacBookPro2,2


sysctlbyname:

-------------------------------------------

hw.machine:i386

hw.model:i386


Chris,
Is is worth filing a bug report or is this well-known?

Daniel

It's an API question, not a tools question, so it's not a job for
Xcode.  (Though you got two tools-based replies that you might find
useful).

The droid you're looking for is sysctlbyname().

x-man-page://sysctlbyname
file:///usr/include/sys/sysctl.h

You're looking for CTL_HW, HW_MODEL.
