After running an osx update today my network card stopped working, it keeps saying the cable is unplugged. It's not the cable cause it works on my macbook. So i want to undo/uninstall the update, but how?

Mac Pro quad 2.66, Mac OS X (10.5.5), Windows XP

    Welcome to Apple Discussions:
    To which update do you refer? There are several recent ones.
    It's not always the update that causes a problem but simply makes a problem more apparent.
    That being said, the only recourse you have to uninstalling an update is to user your TM or other backup.
    The recent Airport update may have updated the firmware, in which case, there is no undo.

    Hello and Welcome to Apple Discussions ...

    Instead of trying to undo an update, try working with the situation. First, on the MacBook turn off Airport, you can do this by going to the Menu Bar, click the Airport icon and click: Turn Airport Off
    Now, shut down your MacBook. Disable any peripherals, like USB ports, Ethernet, everything. If you have a cable modem, turn it off or unplug it. Now, boot the MacBook, turn your cable modem back on, let it recycle, can takes a few minutes. Now turn on Airport from the Menu Bar and see if Airport is functioning as it should.

    If not, try this: Launch Disk Utility, (Applications/Utilities) and Repair Disk Permissions. Select MacintoshHD 10.x.x in the panel on the left, select the FirstAid tab, then click: Repair Disk Permissions. Quit DU when it's finished and reboot. See if Airport is working.

    I agree with Nerowolfe, I do not think there's anyway to UNdo this update other than doing an Archive and Install, but trouble shooting will probably take less time.

    sorry i might have been a bit unclear, i'm talking about the ethernet card in my Mac Pro, it doesnt have an airport card. the airport in my macbook works fine, as does the ethernet card in my macbook. the ethernet card in my Mac Pro keeps saying that the network cable is unplugged. I havent made a backup with TM so i cant use that, is there another way to reinstall the ethernet card?

    ps. i dont know the name of the update, but it's the most recent one including a security update, quicktime update and network update.

    That's ok...

    On the Apple page for MacBookPro is the "Connectivity" specs:

    Built-in AirPort Extreme (802.11n)4
    Built-in Bluetooth 2.1 + EDR
    Built-in 10/100/1000BASE-T Gigabit Ethernet (RJ-45 connector)
    Two USB 2.0 ports
    One FireWire 800 port
    One ExpressCard/34 slot

    If it were me, I'd take the MBPro into an Apple store or an Apple reseller and not try to do this yourself.
