whats going on here?

[henry.oswald]

I'm trying to install a AppleAzaliaAudio.kext (which has been modified to my board by someone else who is using it, although i now believe when i was modifying it i was doing it correctly)

 

I put it in the folder /System/Library/Extensions

 

repair disk permissions

 

deleate Extension.mkext and Extension.kextcache

 

That is correct yep?

 

Then i will reboot and up pop to box's saying that its not been installed properly, now without doing anything at all (i just tested this but its happened about 5 times) the next time i restart i get a no entry sort of symbol come up!

 

What do you think is happening?

Try this: delete the extensions.kextcache and .mkext then using terminal do the repair permissions i.e. chown -R /System/Library/Extensions then do chmod -R 755 /System/Library/Extensions/AppleAzaliaAudio.kext then reboot.

yes. To clarify, go to Terminal and type:

cd /System/Library
sudo rm -rf Extensions.mkext Extensions.kextcache
cd Extensions
sudo chown -R root:wheel AppleAzaliaAudio.kext
sudo chmod -R 755 AppleAzaliaAudio.kext
sudo diskutil repairPermissions /

Then reboot.
