naquaada Posted June 13, 2016 Share Posted June 13, 2016 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.

smolderas Posted June 13, 2016 Share Posted June 13, 2016 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...

naquaada Posted June 13, 2016 Author Share Posted June 13, 2016 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 The harddrive is a WD Black WD1003FZEX.

kosakgroove Posted June 18, 2016 Share Posted June 18, 2016 You know, you could also try to edit your /etc/fstab in Mac OS X so that your Windows NTFS drives dont mount on boot, and so NTFS.kext wont be loaded at all.
