NOTE: I have assumed that you have installed via my guide, any other setups will probably work but are untested

Pre-requisities: Working system on 10.5.4!

1. Download 10.5.5 from here
2. Mount DMG
3. Run Terminal
4. Type 'sudo passwd' and enter your password
5. Set your root password (and confirm)
6. Type 'su root' and enter your password
7. Type 'while sleep 1 ; do rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext ; done' (the terminal window should just 'freeze' (it's processing a loop))
8. Run the updater (MacOSXUpd10.5.5.pkg) from the volume you mounted earlier. When it completes do NOT restart
9. Switch back to the Terminal window
10. Press Ctrl-C
11. Type 'exit' (and then again) to close terminal window
12. Switch back to updater and press restart
13. Party on down!

NOTE: When the system boots, you'll need to reinstall the video drivers, just drop the kexts back onto the kext helper and reboot when prompted.

PS Kudos to netkas for the handy command line!

Ok ... three quick questions oh Mac Daddeh ...

1) Should we backup first ... daft question I know, but I don't have a working "time machine" device at present.

2) My bios is still original 1.05 ... should I update it before doing anything else? (If so ... can it be done under osx?)

3) Are there any real benefits from upgrading?

Which kexts need to be re-installed? All or just the GMA950?

I loaded the GMA950 and rebooted. The system hangs during boot. I can boot into safe mode, so I repaired permissions to see if that would help clear the hang. No good. System still hangs.

Any ideas ?

Thanks

OK, 10.5.5 is now up -- I rebooted again in safe mode, reinstalled ALL the kexts, rebooted and all is well.

1. Why of course! :-)

2. Doesn't matter, you should probably upgrade to the latest tho! I do it with a bootable USB stick with really base command line install on.

3. Changelog is here... doesn't list the warm fuzzy feeling you get inside tho

P

I only had to reinstall GMA950...

P

Yay

1. Ok need to find my usb portable disk to back the system up then.

2. ah best sort that out then.

Followed the above - system won't boot. Tried re-installing kexts in safe mode, still isses. Seems to boot, but just to a blue screen (even in safe mode), so display kext issues maybe. I'll look into it more and post back..

Thanks Paul, this is working perfectly!

I just need to reinstall these kexts:

- gma950
- appleintelframebuffer
- clamshelldisplay

all from your original zipped driver. Wow booting is fast in 10.5.5

One thing is: seems that the battery/acpi somehow is broken because of this update. My battery keep being crossed (No batteries avaiable) although i tried to reinstall the acpibattery kext)

Again thank you Paul!

Restored a backup, and got mine to .5. Was an odd process though.

Installed update, reboot to install disk, remove offending power kext, reboot - 800x600 only.

Installed GMA kext, reboot - screen stays grey don't get login window but i can shutdown with power then enter

use install disk to restore the GMA kext (by copying the old one back from /backup extensions)

reboot, 800x600 again as expected, install GMA adn frame buffer

reboot - black screen and a cursor only. Shutdown as before, and restore kexts

reboot, working now, but no battery and sound

reboot again working fine.

Bizzare. I think it must need 2 reboots to properly sort out changes in kexts, so worth rebooting an extra time after the .5 update to be sure.

Just noticed, quartz extreme/hardware core image support is gone.

Could others check too in system profiler?

paul thanks for the know how... another question: how do you create a bootable usb drive in leopard. i know for windows you gotta use the hp disk utility, but i would guess its easier in os x? just want to know because i hear good (and bad) things about bios update 1.08 that apparently includes the speed boost to 2ghz.

Hi - I had the same problem. I first installed the 10.5.5 update before I read about the CPU kext issue, the install threw up lots of KPs and when I eventually got the machine back to being bootable I also noticed the core image was now software driven and quartz extreme was no longer supported. I never found a solution, so reinstalled from a blank canvas and was more careful doing the update and all is well...

Even reinstalling the gfx kexts after the failed update had no effect, I think when the update failed to complete, it hosed it beyond my feeble attempts to hack it back to health...

So after the full re-install I have 10.5.5 with accelerated gfx back. It does work, but not sure if it was worth the effort

Finally bit the bullet and it worked fine !

Just had to re-do a couple of the kexts more than once.

Hey Paul,

need some help please. Actually i thought i worked through your list but during
the update it stoped and said I have to reboot before the update process was at the end.
So I had to start all over again (completly re installed the OS)
I gues i screwed up at step 7.

could you just confirm.
i type in the whole line and after ;done I hit enter.
Then the system starts a loop.
Do i have to wait until the loop ends and than start the update or do
i do that during the lop ?

probably stupid questions but hope anyone will help me

thanks

sven

s*** it did it again.
after typing the whole Line in Nr 7 and started it came to 5 % and than told me
I had to reboot.

It should work on my wind 100 should it ?

I am starting all over again.

what am i missing ??

i am typing this line and hit enter right ? 'while sleep 1 ; do rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext ; done'

are there spaces after ; and after -rf ?

than i start the update pkg ?

help please

Paul,
I installed the upgrade via system upgrade in mac, I read your review after I upgrade to 10.5.5 and the problem is it's keep looping back over and over again.
Could you help me to undo this? without starting all over again and re-format?
I'm thinking to open the diskutility from booting kalyway DVD 10.5.2 and remove the AppleIntelCPUPowerManagement.kext is that possible?
and if it is possible what is the command line gonna be? I'm sorry I had to ask you alot coz I'm not too familiar with this apple language..
thanks anyway..

Hi there,
do you mind to tell me how to removing offensive power kext from the install disk?
Coz, I'm still in there.
Thanks

I wrote a guide for this - its here http://www.hutsby.net/2008/09/osx-hackinto...start-your.html
