    Instructions for using the AirPort software are available by choosing Mac Help from the Help menu.


  1. The Indigo iMac (Summer 2000) computer with a 350 MHz microprocessor does not include an AirPort card slot. (The parenthetical product description (Summer 2000) refers to the summer of the Northern Hemisphere.)


  2. Never turn your computer on unless all of its internal and extra parts are in place.


  3. The AirPort Card Adapter is required to install an AirPort Card into any AirPort-ready, G3-based, slot-load iMac. This adapter was included with AirPort cards made during the same period as these computers. If you've obtained an AirPort card without the secondary adapter card, you should check with other AirPort users you know to find a spare, or search the secondary market. Because many computers did not require the adapter card, many AirPort users have copies of this adapter which have never been used.

Note: Wireless Internet access requires an Internet service provider (fees may apply) and AirPort (or AirPort-compatible) wireless Ethernet card and base station. Some ISPs are not compatible with AirPort. For more information, see technical document 106590: "AirPort: Requirements for Wireless Internet Access"
