Chapter 1. The Way of the (Mac) WorldHow the Mac Works

Chapter 1. The Way of the (Mac) World
How the Mac Works

Although the title of this chapter appears to convey a subliminal message to purchase a copy of the magazine I routinely write for (buy Macworld! buy Macworld! buy Macworld!), I assure you that I have a loftier goal in mind. You may recall that in this book's introduction, I mentioned that if I could impart a sense of how the Mac functions, you'd be better equipped to troubleshoot and repair it should something go wrong. That's essentially what I'm after in this chapter. If I do my job properly, a little internal light will blink on, and when it does, you'll emit a satisfying, “Oh, now I get it!”

The following is by no means a comprehensive rundown on all the Mac's hardware and operating-system functions. The point isn't to burden you with useless technical detail but to provide you a solid sense of what makes a Mac tick. It's a little like showing you how a blender works. If you understand that the blender needs power to do its job, and nothing happens when you flick the switch, you're likely to suspect an electrical problem. Likewise, if smoke billows from the blender's bottom, and you're sympathetic to the delicate relationship between the motor and rotor, you'll have better luck pinpointing the problem.
