safe to update to 10.5.6 from iATKOS 5i (10.5.5)?

cloudster09 · #1 04-22-2009, 07:24 AM

I have successfully installed 10.5.5 using iATKOS 5i on my eMachine t5048. I have ran software update on everything except for 10.5.6 updater. Will it be safe to do so?

I selected Chameleon bootloader, APIC, and 9.2.0 for my kernel.

Standard stock Apple SW update won't work with ToH 9.2.0 kernel...
The main problem is the mach_kernel being replaced and AppleIntelCPUPowerManagement.kext (causes in most cases KP on load)
Try installing Voodoo kernel or mine and next (after reboot) it shouldn't be a problem anymore to update as long as you keep a copy of the kernel as e.g. mach_kernel.voodoo or mach_kernel.anv and after update before reboot copy that kernel back to mach_kernel

I would recommend Andy's kernel. Never had any problems using the Combo update in Apple Software update with his kernel

you could also run the following in Terminal while running the Combo update:

Code:

while sleep 1; do rm -Rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext; done

I'm not sure about this, but you should be able to safely update with the Delta update- though not the combo. You'd have to download w/o software update, from the Apple Website. Again, I know this is true for Kalyway, but I'm not sure about iAtkos.

Delta update also contains AppleIntelCPUPowerManagement.kext...
Without a disabler or a kernel capable of doing the blocking it will cause a KP and leave the system in a useless state...

quite simple really...
before upgrade:
Open Terminal
Type the following-
sudo cp /mach_kernel /mach_kernel_bak

do the upgrade... don't reboot...
next in terminal type:
sudo cp /mach_kernel_bak /mach_kernel

reboot...

I have updated iatkos 10.5.5 to 10.5.6 without any troubles, on my setup it had the disabler installed by default, though I was running the vanilla kernel.
If you are using a custom kext for the storage controller where your leopard partition is make sure its not overwritten by the update (keep a working copy or put it in /Extra/Extensions.
Also instead of keeping the old 9.2.0 you can try installing Voodoo kernel 9.5.0, just do it before rebooting after applying the update.
