Mavericks always rebuilds Cache

Hi,

 

I have a small problem - Mavericks rebuilds always the kext cache on my system. The 'No Caches' option is not checked on, of course. It's not a too big problem, but it increases the boot time to 56 seconds. El Capitan does not rebuild it's cache every time, so it needs just 39 seconds. The same is on USB boot, but it wasn't always like this. Mavericks booted also with Caches. Perhaps somebody has an idea.

If you or any other process don't touch to "/System/Library/Extensions", then some other corrupted kext cache or kexts with corrupted permissions must be forcing the kernel to refresh the cache. You should investigate "/var/log/system.log" and look for kernel messages. This way you could find the culprit...

Wow, thanks! I checked the system.log and noticed these messages:

 

Kext loading now disabled

Kext unloading now disabled

kext autounloading now disabled

Kernel requests now disabled

 

Well, I never sent Mavericks to sleep, only El Capitan.

 

I also removed sleepfile issues with these commands

 

sudo pmset -a hibernatemode 0

sudo rm /private/var/vm/sleepimage

 

On the Mavericks partition ntfs.kext was defective. After some reboots El Capitan 35 seconds and Mavericks now just needs 24 seconds  :D  The harddrive is a WD Black WD1003FZEX.
