Hi,

Can someone answer me this quick question.

I have UseKernalCache=Yes in cham.plist to speed up the boot process.

I just had a lock up and had to hard-reset.  On trying to reboot it KP, something about zfscompression kext I think, or something like that.

So I tried booting up with -x, same thing, then I tried -f and it booted (long winded version).  Then when I rebooted without -f, it worked as normal.

So does this sound like a corrupt kernelcache?  Does using -f force a rebuild of the kernel cache?

Answers appreciated.  Thanks

As far as I know, -f just bypasses the cache?

Here's how to rebuild the cache on Lion, I suppose it's the same on Mountain Lion:

Trash the folder /System/Library/Caches/com.apple.kext.caches/Startup

Then rebuild the caches from Terminal like this:

kextcache -system-prelinked-kernel
kextcache -system-caches

i trash all the s/l/c and use kext utility after that.

Sadly that does not work for me. I have to boot without user cache.

i wonder if he has .mkext in extra folder.

[fastfwd]

I have .mkext in extra, I will delete and move everything in extension to s/l/e and try that.


It worked thanks!
