Hi,

I'm going to make a really nice utility but btw I want to make sure I don't make mistakes. It's why I would like to know what does Kext Utility :

Here is the console of Kext Utility

Repair Permissions for "/System/Library/Extensions"
What are the correct permission ??

Updating system caches MAC OS X "Lion"................. Done
-- Build time = 35sec.
How does it is build ?

Search "/Extra/Extensions/" folder ... Not Found.
Why is it looking for Extra/Extensions and what would he have done ?

Syncing disk cache ... Done.
What does it means ?

and my final question Is it the same steps for Lion and Snow Leopard ?

Thanks !!

Ok, I found the correct permissions were 775 root:wheel

But can anyone answer my other question plz ?

[jamesst20]

Ok, I'm now in 10.7.2 and it looks that Lion just load every single kexts at the time. Lion isn't using any Extensions.mkext . Does it means that I don't have to build it ?

If there is no Extensions.mkext in lion, why is Kext Utility doing this ? :
Updating system caches MAC OS X "Lion"................. Done
-- Build time = 35sec.

Thanks

I thought many users could have tell me but I guess I was wrong :/ ?

Google "OS X Permissions" first hit: http://support.apple.com/kb/HT2963

Terminal:
man chmod, man chown

Google Lion Kernelcache, Lion Kextcache

etc etc

Good luck with your utility.

[jamesst20]

Haha thanks but I already know about rm, chmod, chown etc..


Here is what I know I need to do (Well for Lion because i don't know anything about SL :S)

S/L/E -> chmod -R 755    chown -R root:wheel
Update System caches (/System/Library/Caches/com.apple.kext.caches/Startup/):
kextcache -system-cache  update system kext info caches for the root volume
kextcache -system-prelinked-kernel  create/update system pre linked kernel

Anything else I need to know ?

After installing your KEXT, run the touch command on /System/Library/Extensions. Then,

• if the release is 10.5 or newer, there's nothing more to do. All KEXT caches except for the prelinked kernel are updated automatically after a short delay; the prelinked kernel is updated after the next restart.

The differences are that:
(1) the touch command returns immediately, rather than when the cache is done rebuilding;
(2) the standard output and standard error of kextcache go into the system log instead of the terminal;
(3) the exit status of touch doesn't reflect whether the rebuild was successful.
