This only affects some computers using a 10BASE-T Ethernet connection. DISCUSSION Symptom You cannot access the Internet or local network resources after updating to version 10.2.8. Your computer's IP address is in the 169.254.x.x range. Products affected o Mac OS X 10.2.8 o Mac OS X Server 10.2.8 o Power Mac G4 (Gigabit Ethernet) - dual 450 MHz and dual 500 MHz computers only o Macintosh Server G4 (Gigabit Ethernet) - dual 450 MHz and dual 500 MHz servers only o Any 10BASE-T network hardware (hubs, switches, routers) o Many DSL (digital subscriber line) and cable modems with 10BASE-T Ethernet ports Note: The built-in Gigabit Ethernet ports on the affected computers can automatically switch between 10BASE-T, 100BASE-T, and 1000BASE-T speeds to match the network they are on. Solution Apple has removed Mac OS X 10.2.8 until an update that resolves this issue can be made available. This update is expected to be available soon, and this document will be updated at that time. Workarounds Consider using one of the following workarounds until the update is available. Note: Wherever a hub is mentioned, a switch or router could be substituted if properly configured. See the device's manual for configuration information. 1. For cable and DSL modems with 10BASE-T ports: Do not connect the computer directly to the modem. Instead, connect the computer and the modem to the same 10/100BASE-T hub. 2. For local area networks (LANs): If you can connect the computer directly to a 10/100BASE-T or 100BASE-T hub, you should do that. If you don't have that option, place a 10/100BASE-T hub between your computer and your normal 10BASE-T connection. 3. If a wireless network is available, use an AirPort card to connect. 4. If you have a third-party Ethernet PCI card, install it in your computer in accordance with the manufacturer's instructions. Change the computer's settings in Network preferences to use this card. 5. If you don't have access to the hardware items mentioned above, you can perform an Archive and Install from your Mac OS X 10.2 Installation disc. After reinstalling, use the Software Update feature of System Preferences to update to Mac OS X 10.2.6. For more information, see technical document 107120, "Mac OS X 10.2: About the Archive and Install Feature". Note: If you perform an Archive and Install installation, it's OK to select Preserve User and Network Settings.
