Crabhunter Posted March 10, 2013 Share Posted March 10, 2013 Anyone got any tips for speeding up boot times in 10.8.2 Using a sata hard drive Windows and Ubuntu both take 27sec but ML is taking 62sec. I have tried use kernel cache = yes but the time remains the same and I lose my trackpad. I've read about using some Snow leopard kexts but I think that broke after10.8.1 Mike Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/ Share on other sites More sharing options...
rob1980 Posted March 10, 2013 Share Posted March 10, 2013 You shouldnt lose your trackpad, do you have an extensions folder in EXTRA? Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1895508 Share on other sites More sharing options...
Crabhunter Posted March 10, 2013 Author Share Posted March 10, 2013 yes but I've put all my kexts in S/L/E Mike Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1895511 Share on other sites More sharing options...
rob1980 Posted March 10, 2013 Share Posted March 10, 2013 try repairing and rebuilding the cache again, use kext wizard, then try booting with kernelcache=yes Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1895512 Share on other sites More sharing options...
iFIRE Posted March 10, 2013 Share Posted March 10, 2013 buy a SSD Disk, mine boot in 9seconds 2 Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1895513 Share on other sites More sharing options...
rob1980 Posted March 10, 2013 Share Posted March 10, 2013 Mine takes 42 seconds on SATA as a comparison for you. (thats from the point chameleon loads OS X to when I have to input my pasword at login) Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1895519 Share on other sites More sharing options...
Crabhunter Posted March 10, 2013 Author Share Posted March 10, 2013 well I've repaired permissions, rebuilt the cache but if I boot with use kernel cache I still lose my trackpad. This might be related to the problem I have after rebooting from Ubuntu into osx. Still no increase on boot time.

Dr. Hurt Posted March 10, 2013 Share Posted March 10, 2013 Mine boots in 30sec on sata hdd. Check system boot in console and see which processes are taking the most time. PS. I lose DVD drive when I use kernel cache. Haven't been able to fix it.

Crabhunter Posted March 10, 2013 Author Share Posted March 10, 2013 @Husarber, now I've lost trackpad, do I just delete make cache? boot time down to 45sec Mike Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1895558 Share on other sites More sharing options...
HUSABER Posted March 10, 2013 Share Posted March 10, 2013 The Solution It’s simple, really: force Lion or ML to rebuild the kextcache and use it to boot. The solution thread on InsanelyMac.com (one of many like it) contains a good explanation of what’s actually happening, but here’s the code to build the cache (Edit: to make OS X also build a cache for your /Extra/Extensions folder, add “/Extra/Extensions” to the code below): sudo kextcache -v 1 -a i386 -a x86_64 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions This *should* accomplish the same thing as setting the “kernelcache = yes” flag in com.apple.boot.plist. What does setting this flag do? Please note that many a contributor to the InsanelyMac.com forum has reported kernel panics resulting from using this flag, while others have reported Lion or ML booting fine (and quickly) but ignoring the kernel extensions placed in the /Extra/Extensions directory. I have ONLY created the Extensions.mkext using the terminal code above; I HAVE NOT added the “kernelcache = yes” flag to com.apple.boot.plist. The result? My machine now boots in seconds instead of minutes. That simple 1 Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1895563 Share on other sites More sharing options...
Crabhunter Posted March 10, 2013 Author Share Posted March 10, 2013 Well although this did shave 20sec off the boot time I had no trackpad I had to delete the mkext to boot with trackpad. I'm not sure which kext is responsible for it, I assume it must be a usb mouse driver or perhaps ps2 mouse driver as it does not show up in settings as a trackpad. Whichever kext it is it is obviously not being added to the mkext whichever method I use. I think this is also why I have trouble with it when I restart from Linux into osx.

artur_pt Posted March 10, 2013 Share Posted March 10, 2013 hello if u have all kext in system/library/extensions ... run in terminal sudo kextcache -prelinked-kernel that rebuild u kernelcache and that is the proper way to run ML copy from terminal the result of command and post about u trackpad ... is a a ps2 kext , but u must know what brand is u trackpad.. sinaptics , elantech.. etc and use a proper ps2 kext for it good hack Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1895640 Share on other sites More sharing options...
Crabhunter Posted March 10, 2013 Author Share Posted March 10, 2013 Well Husabers kext didn't work and between osx, windows and linux I cannot find out the make of my trackpad. I'm going to concentrate on my LAN for a while.

Gringo Vermelho Posted July 6, 2013 Share Posted July 6, 2013 Kernel file /mach_kernel does not contain requested arch: i386 nvenet.kext - no dependency found for com.apple.driver.NVSMU. nvenet.kext is missing dependencies (including anyway; dependencies may be available from elsewhere) nvenet.kext - no dependency found for com.apple.driver.NVSMU. nvenet.kext - no dependency found for com.apple.driver.NVSMU. Prelink failed for com.apple.nvenet; aborting prelink. Failed to generate prelinked kernel. nvenet.kext is an Apple shipping driver, it's a plugin inside IONetworkingFamily.kext. It seems strange that it should cause trouble on a system where it's not even needed, it's a driver for nforce chipset ethernet. Maybe it's an older version that has been patched - is this a retail install or was it done with a distro? No matter, try simply deleting it - it's totally safe to delete since you have no nforce ethernet hardware - assuming this is happening on the Gigabyte motherboard in your signature, of course. Go to /System/Library/Extensions, right-click IONetworkingFamily.kext, click "show package contents" then go to Contents/PlugIns and trash nvenet.kext. Type your password when prompted. Then try rebuilding caches and the prelinked kernel again. NVSMU.kext also ships with OS X - it's probably a driver for the system management unit on macbooks (and iMacs?) with nvidia chipset. Contrary to popular belief, It's not part of the nvidia video card drivers. You could simply delete this as well. If you decide to update to 10.8.3 or .4 definitely download and run the full combo update instead of using Software Update. Both kexts will be restored but they should no longer cause any trouble. 1 Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1930604 Share on other sites More sharing options...
Ega Indra R Posted July 7, 2013 Share Posted July 7, 2013 I use iATKOS , I already updated to 10.8.4 I'll try delete the kext and post the result, thanks I try again and here is the result : Kernel file /mach_kernel does not contain requested arch: i386, that's only cause ML is x64 kernel righr? so Its working now thank you Link to comment https://www.insanelymac.com/forum/topic/286948-solved-speeding-up-boot-time/#findComment-1930629 Share on other sites More sharing options...
Gringo Vermelho Posted July 7, 2013 Share Posted July 7, 2013 So I was right lol....glad you got it working. Yes that message is normal on Mountain Lion. If you'd done a retail installation you would never have had this problem.
