If you ask Apple, dial-up modems are dead. Macs don’t even come with built-in modems anymore. You can get a non-Apple USB modem for $50, but clearly Apple is trying to shove the trusty dial-up technology into the recycling bin.
Still, millions of people never got the memo. If you’re among them, then you need to sign up for Internet service. Once you’ve selected a service provider, you plug its settings into the Network pane of System Preferences. You get the necessary information directly from your ISP by consulting either its Web page, the instruction sheets that came with your account, or a help-desk agent on the phone.
Further details on OS X’s dial-up modem setup are in the free appendix to this chapter, “Setting Up a Dial-Up Connection.” It’s available on this book’s “Missing CD” page at www.missingmanuals.com.
