Need Help Please...AppleYukon.kext (How to force it to load) <Solved!>

[ScottieBoi]

Ok here's my situation....

 

I have a Yukon 88E8050 onboard NIC

 

I've edited the AppleYukon.kext file as described in other posts on that particular card. When I reboot...nothing happens.

 

Now...if I boot in Safe Mode (-x), it will work. If I reboot not using safemode...the Network configuration screen shows the device (lists it as PCI Ethernet Slot PCI), but its greyed out, and it wont work. It's also listed in the "About This Mac" If I reboot using safemode, it works again.

 

Its infuriating! Booting in safe mode is a much longer process and its quite annoying. This problem does not occur if I use a LinkSys USB network adapter. It works just by booting in regular mode. You may ask...why not just use the USB adapter....because its annoying having to switch back and forth when going from Mac to Windows. (My Windows doesnt like that adapter for some reason.)

 

I know I'm just missing something....its almost as if when I boot into the OS using regular mode (Enter key at Darwin)...that this kext isn't loading. Do I need to add the particular kext (AppleYukon) or maybe (IONetworking) into the "Startup?" If so, how do I do this?

 

Thanks for any help!.....I'm very eager to get this to work as this is my last hurtle...I've got sound and graphics card working great.

 

PS...I am using 10.4.6

Hi ScottieBoi

Have you copied the AppleYukon.kext to /System/Library/Extensions/

 

Once you have dragged the file into /System/Library/Extensions/ you will need to Authenticate

with your administrative password. Once you have authenticated you will need to open a terminal

window & paste the following commands into the terminal:

 

sudo chmod -R 755 /System/Library/Extensions/AppleYukon.kext

[authenticate again]

sudo chown -R root:wheel /System/Library/Extensions/AppleYukon.kext

sudo kextload -v /System/Library/Extensions/AppleYukon.kext [manually load kext]

 

When you have manualy loaded the kext Successfully you should get the following text or something similar.

Once the kext is successfully loaded clear the kext cache to do this copy and paste the following into a Terminal:

sudo rm /System/Library/Extensions.mkext

[This forces the system to re-examine all of the drivers and rematch during the next boot cycle.]

 

Now Reboot. Let me know if this works for you

Thanks Caladan It worked.

 

I had tried messing around with the kextcache last night as well....but I was missing a crucial step. What I was doing was deleting the file itself (kectcache), then rebooting...it would force all the kext's to reload...but as soon as it got to the yukon, it would freeze. Upon a reboot from this error, I got a message saying AppleYukon wasn;t installed correctly.

 

Looks like I was missing the commands you gave me. Out of curiousity, was it permissions that was fouling me up?

 

In either case....THANKS SO MUCH!

hello! I'm new around. after install, when in -v mode the loader stops. i saw cpu, usb, video, lan, acpi ok BUT! it stop at login window with this mesg: "cannot lookup child" and "mDNSResponder-Adding browse domain local. after reading in forum I think it's from the lan card- Yukon 88E8050 onboard NIC. Any advice? THANX

Hi ScottieBoi, Glad it all worked out for you. Yes I believe what was happening it that you hadn't given

the appropraite permissions for the kext to load and then when you deleted the kextcache file and rebooted

caused a loop in effect. But once you had given the correct permissions and emptied the kextcache and

manually loaded the kext and it was successful. All you had to do was reboot and now you're up and running. Excellent News & great to see it actually worked.

Question:

 

I am having trouble with my usb kext which do not load at startup so i load it manually and then it works perfectly so after loading it manually if I run the same command as you thaught will it then automatically load the kext from the next boot.
