Allan Posted March 27, 2014 Share Posted March 27, 2014 Original explanation: Common boot options -fIgnores kext caches during bootup on Mac OS X Snow Leopard. If you did not install a kext properly, your kext cache will be damaged, and Mac OS X might become unbootable unless you use this boot flag. The kext cache was replaced by the kernel cache in Mac OS X Lion, so theoretically, the -f boot flag should no longer work; however, this boot flag can still help some Hackintoshes boot (for reasons unknown).UseKernelCache=YesMac OS X Lion, Mountain Lion, and Mavericks can use the kernel cache to install kexts, allowing Mac OS X to boot faster. However, the kernel cache is turned off by default, and you have to enable it by using the boot flag "UseKernelCache=Yes" (without quotation marks). If Mac OS X is booting extremely slowly on your Hackintosh, the kernel cache might be malfunctioning. In addition, some laptops have trouble with the kernel cache feature. In these cases, you can turn the cache off with "UseKernelCache=No" (without quotation marks). Turning off the kernel cache is equivalent to using the "-f" bootflag in Snow Leopard.

carbo178 Posted March 27, 2014 Share Posted March 27, 2014 Have you extensions.mkext in Extra? Link to comment Share on other sites More sharing options...

carbo178 Posted March 27, 2014 Share Posted March 27, 2014 Well, this is the problem. First of all open chameleon wizard, in tab "Extraction" drag 'n drop extensions.mkext in the window and click "Extract". You find a folder in desktop called "mkext content". From this folder install (if presents) NullCPUPowermanagement.kext and FakeSMC.kext in S/L/E with kext wizard, delete extensions.mkext, repair permissions, rebuild cache and reboot Link to comment Share on other sites More sharing options...
keiner99 Posted March 27, 2014 Author Share Posted March 27, 2014 in extensions.mkext are only 2 kexts: Ispcidrv.kext and Patched_10.7_AppleRTC.kext what functions does the two kexts have in mavericks 10.9.2? Link to comment Share on other sites More sharing options...
carbo178 Posted March 27, 2014 Share Posted March 27, 2014 Delete the file and reboot, the kexts included is not necessary for your system, also delete lspcidrv.kext from S/L/E Link to comment Share on other sites More sharing options...

nyolc8 Posted March 28, 2014 Share Posted March 28, 2014 I had the same problem with my vga card, it only worked with -f or usekernelcache=no. Then I re-made kernelcache with these Terminal commands and this fixed it for me: sudo kextcache -system-prelinked-kernel sudo kextcache -system-caches Try it, might work for you too.

Benjudas Posted May 2, 2014 Share Posted May 2, 2014 I think that it can be an IRQ conflict with your hpet. Try to add or change hpet's IRQ in your dsdt. About the sound assertion, plug a HDMI display and maybe it will dissapear. Hope it helps. Link to comment Share on other sites More sharing options...
