How to Switch to Apple Mac Hook Ups on the Same Cable Modem
Your cable modem can be used with a Macintosh or Windows computer. If you are switching your cable modem from a Windows computer to a Mac you only have to clear out the modem's internal memory so it works with a new computer. You can then optionally set up your Mac to share the cable Internet connection wirelessly to other wireless computers and handhelds.
