I was wondering how do I update my leopard software to the version 10.5.5 that's avalaible in software update? The last time I tried to it, it grayed out my screen and told me I had to restart my comp, and then when I did it never booted back to my desktop, so I am just wondering how I go about this update?

my specs are
Compaq EVO D310
1.5 GB DDR 2 RAM
Nvidia GeForce 5500 FX
AC'97 Audio
Lite-On DVD/CD Burner
Pentium 4 @ 2 Ghz
Mac OS Leopard 10.5.4

Steven,

This is how I managed to get from 10.5.4 upto 10.5.5:

(1) Updated to 10.5.5 with Vanilla Kernal via the Apple Website
Apple Update 10.5.5
(1.1) Download the update
(1.2) Open Terminal
(1.3) type: sudo -s
(1.4) type: while sleep 1; do rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext; done
(1.5) run the update
(1.6) when request to restart DON'T, kill the terminal command (CTRL+C or CTRL+X) first
(1.7) then click restart as requested
(1.8) type: update -v
(1.9) reboot again

Thanks! That worked perfectly :-)
From iDeneb 10.5.4 -> 10.5.5

Hi,

What if I was to run an update with those instructions, but I had Pentium 4 processor and XNU kernel?
Would the update fck up my system?
Or could I update directly via apple's software update without any worries?

i didnt backup AppleIntelCPUPowerManagement.kext
can someone give me a link to download it?
im currently in safe mode thanks!
