~pcwiz Posted September 25, 2007 Share Posted September 25, 2007 Hi, My specs are below in my signature. I want to update from 10.4.9 to 10.4.10 and I have a copy of the PascalW Delta Updater. I am currently running Uphuck 1.4iR3 with the Semthex 8.8.1 kernel (from the JaS 10.4.8 disc) because the 8.9.1 kernel is unstable on my system. I have backed up my kernel and extensions. My system is known for being unstable with newer kernels so I'm wondering: If something screws up after installing the update, could I restore my kernel and extensions using single user mode? Anything else I should do before installing? Waiting for a thumbs up to install pcwiz Link to comment https://www.insanelymac.com/forum/topic/64455-update-to-10410/ Share on other sites More sharing options...
eXcalibUr88 Posted September 27, 2007 Share Posted September 27, 2007 yes you can do that.. if you can boot to -s after the update... there is an easier way to do it if you are dual booting with windows.. you can install macdrive to access your MAC HD and transfer the kexts and extensions by dragging and dropping them.. repair the permissions using the DVD after..

josh256 Posted September 27, 2007 Share Posted September 27, 2007 You should probably revert to your 8.8.1 kernel and System.kext before rebooting (if you're unsure about newer kernels). J.

~pcwiz Posted September 27, 2007 Author Share Posted September 27, 2007 I have my kernel backed up so I can boot into the 8.8.1 kernel at boot by typing: /mach_kernel.881 at boot prompt.

~pcwiz Posted September 28, 2007 Author Share Posted September 28, 2007 I updated and it went pretty well Everything works in 10.4.10 but I still have to use the 8.8.1 kernel & System.kext. Like I said, any kernel higher than 8.8.1 is unstable. With the 8.10.1 kernel, it just loads the extensions and the machine reboots. Does anyone have any idea why my system can't run any kernel higher than 8.8.1?

~pcwiz Posted September 28, 2007 Author Share Posted September 28, 2007 First of all backup your old kernel and System.kext file. Run the updater and BEFORE clicking the Restart button open up Terminal and restore the kernel and system.kext. Really simple...

lordhex Posted October 6, 2007 Share Posted October 6, 2007 First of all backup your old kernel and System.kext file. Run the updater and BEFORE clicking the Restart button open up Terminal and restore the kernel and system.kext. Really simple... I did the following over a 10.4.8 JaS installation on a Dell C640 which was working perfect with wireless, audio, katana drivers for video: cd / mkdir BACKUP cp mach_kernel /BACKUP cp -R /System/Library/Extensions/System.kext /BACKUP then applied the Apple update 10.4.10 before I restarted cd / cp -R /BACKUP/System.kext /System/Library/Extensions cp /BACKUP/mach_kernel . rm -f /System/Library/Extensions.kextcache rm -f /System/Library/Extensions.mkext just to make sure chmod -R 755 /System/Library/Extensions/ chown -R root:wheel /System/Library/Extensions and reboot The system comes back, goes for a fraction of a second in graphical mode then crashes with a kernel panic about some ACPI it could not load. What I can do to restore the system back to a functional state? thank you in advance.

~pcwiz Posted October 6, 2007 Author Share Posted October 6, 2007 This is what I did. Before the update: Open Terminal. Type in: sudo -s [enter password] cp /mach_kernel /mach_kernel.backup cp -R /System/Library/Extensions/System.kext /Backups/ Then after updating (before you click the Restart button on the updater): Open Terminal Type in: sudo -s [enter password] cp -R /mach_kernel.backup /mach_kernel cp -R /Backups/System.kext /System/Library/Extensions/ And thats it! Click the Restart button. Link to comment https://www.insanelymac.com/forum/topic/64455-update-to-10410/#findComment-464167 Share on other sites More sharing options...

~pcwiz Posted October 6, 2007 Author Share Posted October 6, 2007 Try booting with your old kernel. Boot OS X and go into the F8 boot prompt. Type in: /BACKUP/mach_kernel and hit enter. It should boot OS X with your old kernel and you can them restore it to the way it used to be.

~pcwiz Posted October 10, 2007 Author Share Posted October 10, 2007 Well then theres more wrong with the install than just the kernel. Go into single user mode and restore you old extensions and kernel.
