How Tiger 10.4.10 Killed My Wireless and How I Fixed it

As a seasoned Mac user I know to be careful when updating my Mac. In the five or so years that I’ve been using OS X I’ve only really hit problems once before 10.4.10 came out, so I’m usually not too worried. There are lots of people that claim an update killed their computer— a slightly dubious claim in my opinion— but updates can make some things unpleasant.

After safely updating my iMac I decided to update my production machine, a MacBook Pro. Everything seemed fine until I tried to go onto the internet. What happened was that I could connect to the router, I could even get to the router’s control panel, but I couldn’t do anything else. No internet, no network.

During my troubleshooting I noticed that when I removed the security settings I could get online. But there is no way that is an acceptable solution.

So I downloaded Apple’s airport update from a while back and saw which files it was updating. Then I downloaded the 10.4.9 combo update and replaced the file on my computer with the one in there. In case this happens again, or if anyone else has this problem I’ve saved the file and put in online (to avoid the massive 10.4.9 combo download). Here are the steps to getting wireless back:

  1. Download and unzip the file to your desktop
  2. Open terminal and paste this in:
    sudo cp -R //System/Library/Extensions/IO80211Family.kext/ /System/Library/Extensions/IO80211Family.kext.backup/;
    sudo mv ~/Desktop/IO80211Family.kext/ //System/Library/Extensions/IO80211Family.kext/;
    sudo chown -R root //System/Library/Extensions/IO80211Family.kext/;
    sudo chgrp -R wheel //System/Library/Extensions/IO80211Family.kext/;
    diskutil repairPermissions / -v;
  3. Restart the computer and hold down the shift key until you see the spinning circle, this boots the computer in “safe mode” which will ensure the permissions are all set correctly
  4. Once the computer finishes booting you can restart it normally

That did it for me anyway, I’m cruising the information super highway again! Of course this is done at your own risk and you should backup important files first. I don’t take any responsibility for anything not working or messing things up.

update: Apple’s latest wireless release (2007-004) broken my wireless again.
