Reset fan behavior after 10.3.8 update
Authored by: junkiesxl on Mar 07, '05 03:04:05PM

The fan on my PB 12" rev a, did the same thing. It seems Apple has once again (like a couple of other updates) replaced the AppleADM103x.kext.

Replacing this with the AppleADM103x.kext from 10.2.8 solved the problem of my fan sounding like a plane.

Note: To get the original AppleADM103x.kext download Pacifist and 10.2.8 update from Apple. Then use pacifist to extract the .kext
It seems like Apple wants to be sure none of the PBs gets too hot, altough they launched like the hottie its is.

trouble replacing .kext
Authored by: sahnert on Mar 11, '05 03:43:02PM

I tried this and when I restarted it said the extension wasn't installed properly and can't be used. I'm afraid that means I don't have an extension to control the fan. I did save the original file from 10.3.8, but if I replace it won't it give me the same message? This is how I did it:
I dragged the old .kext file into the extensions folder and it said a newer version already exists. Replace? yes. Then it said you don't have permission. Authenticate? yes. Entered my password and it copied over I guess. Then I restarted today and it said that the extension was not properly installed and cannot be used. Is there a better way to do this?
For the record... I used the .kext from 10.2.3 rather than 10.2.8. Maybe that makes a difference?
let me know if you have an ideas. Thanks

trouble replacing .kext

I am about to display my relatively paltry knowledge of Unix--I have no idea if this will work, but give this a try in Terminal:

sudo touch /System/Library/Extensions

...then restart the Mac.

This is sometimes (always?) needed after you do the sort of extension moving you did, and also after trashing cache files (or just /System/Library/Extension.kextcache, /System/Library/Extensions.mkext, and /System/Library/Caches/ to reset the cache info.

Somebody set me straight if I'm imagining things.
