lord_muad_dib Posted April 28, 2008 Share Posted April 28, 2008 i doubt it would speed up boot time, extension.mkext contains only what is found suitable for your system and it is the only file loaded everytime, not the whole extensions folder Link to comment Share on other sites More sharing options...

westwaerts Posted April 28, 2008 Share Posted April 28, 2008 look in system profiler, what extensions are loaded. if you dont have any special devices only sometimes plugged, all you need for running is listed there. Link to comment Share on other sites More sharing options...
Envying Posted April 28, 2008 Share Posted April 28, 2008 run kextstat in terminal, you will get a list of kext files loaded for your current system. Link to comment Share on other sites More sharing options...

Slice Posted April 29, 2008 Share Posted April 29, 2008 Some kexts may be not loaded as it loads dynamically when needed. You can safely delete all kexts with PowerPC architecture (look in Get Info). They are never works in hackintosh. Very useful program to clean disk space is Monolingual. They erase all extra languages support except your needed and PowerPC codes from UniverssalBinary. I free 400Mb without any problems. Link to comment Share on other sites More sharing options...
susu2k Posted April 29, 2008 Author Share Posted April 29, 2008 hi, great answers thanks! so did someone experience faster bootup? what do you mean with dynamically? so it actually caches the kexts and it will not result in faster boot times so? ahhh ok i just saw what you mentioned with extensions.mkext :censored2: very cool thanks regards Link to comment Share on other sites More sharing options...
ktz Posted December 5, 2013 Share Posted December 5, 2013 I am interesting in deleting unused kexts on 10.9 mavericks. I can see some bluetooth loading on startup or something but I haven't any device like this. So deleting unwanted kexts may speed up boot process?

PippoX0 Posted December 5, 2013 Share Posted December 5, 2013 To speedup booting process, You just use kernelchache. Use the following in terminal to rebuild your cache: sudo kextcache -v 1 -a i386 -a x86_64 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext -z /System/Library/Extensions /Extra/Extensions Remove -f flag and insert UseKernelchache=Yes in org.chameleon.Boot.plist. Now your pc boot faster Osx 1 Link to comment Share on other sites More sharing options...

Slice Posted December 7, 2013 Share Posted December 7, 2013 Use UEFI Clover with FastBoot settings. 10 seconds even with ordinary HDD. 1 Link to comment Share on other sites More sharing options...
ktz Posted December 9, 2013 Share Posted December 9, 2013 Yea. SSD it's a right way. I just want to understand how OS works. BTW I have old hardware withou UEFI so this FastBoot option is not for me at this time Link to comment Share on other sites More sharing options...
