This article explains how to make a Macintosh computer ready to use the Internet.

1. Make sure your computer has the right version of system software.
• Computers with a 68030, 68LC040, or 68040 microprocessor should have System 7.5.5 or later with Open Transport networking enabled.
• Computers with a PowerPC microprocessor should have Mac OS 9.
2. Make sure your computer has enough memory (RAM).
• Computers with a 68030, 68LC040, or 68040 microprocessor should have at least 16 MB.
• Computers with a PowerPC microprocessor should have at least 32 MB (64 MB recommended).
3. Make sure your computer has the kind of modem and modem connection your Internet service provider (ISP) requires.
• Many Internet services use dial-up, or analog modems. These kinds of modems connect to a computer's serial port. At a minimum, your modem should be able to transfer data at 14.4 kbps. A 56 kbps modem is recommended.
• Digital subscriber line (DSL) and cable modems connect to a computer's Ethernet port. Not all Macintosh computers have an Ethernet port. If your computer does not have one, check with an Apple reseller to see if one can be added.
4. Subscribe to an Internet access service of your choice.
5. Install software provided by your ISP.
• If your computer is using System 7.5.5, your ISP generally provides dial-up and support software. If your computer is using Mac OS 9, Remote Access dial-up software is already installed.
• Your ISP may also provide you with an Internet browser, such as Netscape Navigator or Microsoft Internet Explorer, and an email program, such as Microsoft Outlook Express. These programs are part of Mac OS 9 and are automatically installed.
