Problem rebuilding kextcache

[ozofeliz]

Hi. I've Mountain Lion 10.8.4. I have a problem with the vmware kext. I tried to reubuild kext cache with
kextcache -system-prelinked-kernel and told me:

Kernel file /mach_kernel does not contain requested arch: i386

How to know what kext is causing the problem ?

P.S. I repaired permissions disks.

Try this in Terminal: sudo touch /System/Library/Extensions
If this doesn't work, try using Kext Wizard to rebuild them.


Hope I could help,

Recently encountered a similar problem, except with yosemite after the 2016-011 security update. System always loads in a -f , flagged state and checks every kext , instead of reading the kext cache > the system worked normally before. Tried multiple methods of cache rebuild? Is this an update side effect or possibly having to use the kext dev mode tag does this ?|

The problem is solved by changing compression mode to lzss in usr/standalone/bootcaches.plist +
rebuilding caches and then adding flag, kernel cache / s/l/e/ com.apple.kext.caches/Startup/kernelcache to cham boot plist for legacy chameleon , Yos 10.10.5 + security update & etc.
