dsalsa Posted July 1, 2011 Share Posted July 1, 2011 Help please after I updated from 10.6.7 to 10.6.8 I am unable to get my computer to boot. I don't seem to be getting a kernel panic the computer just stops loading. Attached is a photo of the screen were it just stops at. Sorry the photo is so bad. Apple should have put better cameras in their iPod Touches. I know you can't see the attachment. I don't know how to post it.

Boot into single user mode if you could, repair permission by chmod and chown. Reboot.

I know how to boot in to single user mode (-s) but could you give me a short and simple way to repair permission by chmod and chown if I am able to boot in single user mode. I googled it but it's kind of confusing what I found. Thanks Link to comment https://www.insanelymac.com/forum/topic/261199-no-boot/#findComment-1707285 Share on other sites More sharing options...

I googled it but it's kind of confusing what I found. Thanks UPDATE: Was unable to boot in to single user mode (-s) so I booted with my snow installer DVD used Disk Utility and repaired permissions. There where permissions repaired but there is no change when I try to boot. Not getting a KP but it just seems to stop at the same spot as mentioned before Link to comment https://www.insanelymac.com/forum/topic/261199-no-boot/#findComment-1708089 Share on other sites More sharing options...
Foxic Posted July 4, 2011 Share Posted July 4, 2011 Try rolling back your IOUSBFamily.kext to the version you were using previously as is stops on what I can only assume is IOUSBMassStorageClass.kext, possibly try rolling back that one too if no success. Are you rebuilding caches using terminal or just fixing permissions using disk utility from the OS X boot disk?

Are you rebuilding caches using terminal or just fixing permissions using disk utility from the OS X boot disk? On the specific partition (10.6.8) I only fixed the permissions using disk utility. On another partition (10.6.5) which is actually the one I'm using right now I Repaired Permissions, Cleared Extensions Cache and Cleared User Application Cache, but not through the terminal I was using a utility 0Sx86 Tools as I'm not very familiar using the terminal. By the way the reason I used that utility to repair and clear is because after I changed my SleepEnabler.kext (in Extra Extensions) I couldn't boot without typing pmVersion=0 every time I booted along with cpus=0 but that's another story. I don't have to use pmVersion=0 anymore but I lost my trackpad and battery meter.

Foxic Posted July 4, 2011 Share Posted July 4, 2011 If you're installing/changing kexts using the boot disk you need to run the following in terminal once you have finished and before you try to boot back to the partition you are modifying. Enter the following commands to repair the permissions on your “/Extra” directory: $ sudo chown -R 0:0 /Extra $ sudo chmod -R 755 /Extra You may also need to repair the permissions on your “/System/Library/Extensions” directory: $ sudo chown -R 0:0 /System/Library/Extensions $ sudo chmod -R 755 /System/Library/Extensions Now build the Extensions.mkext for /Extra/Extensions in /Extra with the following command. $ sudo kextcache -v 1 -a i386 -a x86_64 -m /Extra/Extensions.mkext /Extra/Extensions You may also need to rebuild the Extensions.mkext for the “/System/Library/Extensions” directory: $ sudo kextcache -v 1 -a i386 -a x86_64 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions The paths I have put in here are local paths, so they would work on the currently running partition. If you're doing this from the boot disk you will have to amend the paths to suit your needs. e.g. /Volumes/<YOUR PARTITION NAME>/System/Library/Extensions Link to comment https://www.insanelymac.com/forum/topic/261199-no-boot/#findComment-1708264 Share on other sites More sharing options...

If you're doing this from the boot disk you will have to amend the paths to suit your needs. e.g. /Volumes/<YOUR PARTITION NAME>/System/Library/Extensions Going back to my 10.6.8 partition which is the one I'd rather get back up and running there was no "IOUSBFamily.kext" or "IOUSBMassStorageClass.kext" to roll back to besides even if there was I don't know what the previous version I was using was. On my 10.6.5 which might have to be my new partition if I can't get the 10.6.8. to boot I have a concern in two of your instructions: $ sudo kextcache -v 1 -a i386 -a x86_64 -m /Extra/Extensions.mkext /Extra/Extensions and $ sudo kextcache -v 1 -a i386 -a x86_64 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions My concern is the 64. I'm assuming you were assuming I had a 64 bit computer, now my desktop is a 64 bit computer but I can't seem to be able to install Mac on it, my laptop where I have Mac OS X installed is only a 32 bit machine. Should I change the 64 to a 32 or maybe don't need to put 64 or 32 or the last option is I guess the 64 could have nothing to do with what bit my computer is. Sorry for my ignorance.

Foxic Posted July 5, 2011 Share Posted July 5, 2011 That will compile the mkext for i386 (32bit) and x86_64(64 bit). When I say rollback the kext, I mean to the last known working version, if 10.6.5 was working use the kexts from there, just make sure you back everything up (i.e. copy your s/l/e folder to desktop) before you start editing things.

After typing "$ sudo kextcache -v 1 -a i386 -a x86_32 -m /Extra/Extensions.mkext /Extra/Extensions" this is what I got: Unknown architecture x86_32. No work to do; check options and try again. usage: kextcache <mkext_flag> [options] [--] [kext or directory] ... kextcache -system-mkext [options] [--] [kext or directory] ... kextcache -prelinked-kernel <filename.

Effendi Posted July 5, 2011 Share Posted July 5, 2011 Read properly: x86_32 is NOT x86_64. Link to comment https://www.insanelymac.com/forum/topic/261199-no-boot/#findComment-1709394 Share on other sites More sharing options...
