Chapter 4. Startup

 < Day Day Up > 

The most striking difference between Mac OS X and other flavors of Unix is in how Mac OS X handles the boot process. Gone are /etc/inittab, /etc/init.d, and /etc/rc.local from traditional Unix systems. In their place is a BSD-like startup sequence sandwiched between a Mach[*] foundation and the Aqua user interface.

[*] Mach is a microkernel operating system developed at Carnegie Mellon University. The Mac OS X kernel, xnu, is a hybrid of Mach and BSD.

This chapter describes Mac OS X Tiger's startup sequence, beginning with the BootX loader and progressing to full multiuser mode, at which time the system is ready to accept logins from normal users. The chapter also covers custom startup items, network interface configuration, and Mac OS X's default periodic jobs.
