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.
Apple has released new versions of Mac OS X 10.2.8 that resolve or prevent this issue. If you have already used a workaround to get the affected computer back on the Internet, follow these steps for the update:
- From the Apple menu, choose System Preferences.
- From the View menu, choose Software Update.
- Click the Update Now button.
Software update will present the correct version of the 10.2.8 update for your computer. Follow the onscreen prompts to install it.
If your computer cannot connect to the Internet, you may be able to use one of the workarounds below.
If you are affected by this issue but cannot use any of the workarounds, please contact AppleCare in your region for assistance.
These workarounds present several different ways to resolve the issue. The first workaround describes using a different computer to get the software. If you have a 10/100Base-T Ethernet hub, the second and third workarounds can connect the affected computer to the Internet to get the update. If you have an extra PCI Ethernet card or AirPort Card, either could also be used to connect the affected computer to the Internet. Performing an Archive and Install can also resolve the issue.
- Go to another computer, download an installer, then burn the installer onto CD for transport to the affected computer. Standalone installers are available from Apple Downloads.
- If the affected computer connects to a cable or DSL modem with a 10BASE-T port: Do not connect the computer directly to the modem. Instead, connect the computer and the modem to the same 10/100BASE-T hub. This should allow the affected computer to access the Internet.
- If the affected computer is on a local area network (LAN): 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. This should allow the affected computer to access the Internet.
- If a wireless network is available, use an AirPort Card to connect the affected computer to the Internet.
- If you have a third-party Ethernet PCI card, install it in the affected computer in accordance with the manufacturer's instructions. Change the computer's settings in Network preferences to use this card.
- 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 10.2.8. If you perform an Archive and Install installation, it's OK to select Preserve User and Network Settings.
