f you’re lucky, this is a wasted chapter. After all, you’ll probably never have to
install Mac OS X (assuming it came preinstalled on your Mac), and in the best
of all technological worlds, you won’t have to do much troubleshooting, either.
But here’s this chapter, anyway—just in case.
Installing Mac OS X 10.4
If your computer came with Mac OS X 10.4 already installed on it, you can skip this
write-up—for now.
But if you’re running an earlier version of the Mac OS and want to savor the X experi-
ence, this chapter describes how to install the new operating system on your Mac. It
also prepares you for the inevitable arrival of Mac OS X 10.5, 10.6, or whatever else
comes down the pike.
Four Kinds of Installation
Mac OS X requires a Mac with a G3, G4, G5, or Intel processor, 1.5 gigabytes of free
disk space, and (for reasonable speed) 256 megabytes of memory or more. If all of
that checks out, then read on.
The Mac OS X installer can perform a number of different installations. For example,
it can put a copy of Mac OS X 10.4 onto a hard drive that currently has:
• Nothing on it. If you one day have to erase your hard drive completely—because
it’s completely hosed, or, less drastically, because you you’ve bought a new, empty
external hard drive—see “The Basic Installation” on the next page.
