Can I upgrade to 10.5.6? [YES YOU CAN - Edited to describe method]

[Guest johnwin]

Thanks to Paul and all the other geniuses here I have managed to make myself a lovely little Mac OS X 10.5.5 netbook for a little over 200 quid.

I've seen discussions on upgrading to 10.5.6 on the MSI Wind Forums but they all refer to starting with the msiosx86 distro. I started with the kalyway version.

Is there a route to upgrade to 10.5.6 from Kalyway or do I need to start over with msiosx86?

Any help would be appreciated. Thanks.

I see a couple of hundred people have read my post above so I thought I'd give you all an update.

I found the post below on the insanelymac forum:

http://www.insanelymac.com/forum/lofiversi...hp/t152801.html

and decided to give it a try.

It worked - I am now running 10.5.6 with no problems and installed iWork 9.0 (which requires 10.5.6)

I followed the instructions given by maxpersg. The only part I did not manage to do (user error?) was the bit about editing 'Dont Steal Mac OS.kext'

I could not find the text so just moved on to the next stage and crossed my fingers. It worked.

Also I did not use OSX86Tools - I installed all the kexts via Kext Helper instead.

The only stumbling block was that on reboot my keyboard did not work. I don't have a USB keyboard but then realised that I could still reinstall Paul's kexts using the mouse and the on screen keyboard to enter my password :-)

One more re-boot and all done.

Below is a slightly edited version or maxpegs instructions for getting from 10.5.5 to 10.5.6 (I've just improved the English a little as I don't think it is his first language):

Upgrading to 10.5.6

Files required:

- disabler.kext

- apple decrypt.kext

- OSX86Tool Utility

- OSX 10.5.6 update

Process:

1. Install OSX86tool Utility and launch it

2. Use that to install the two .kext files by clicking “install .kext files” (I used Kext Helper)

3. Reboot after installation of the 2 kexts above

4. Before launching update, go into terminal (utilities -> terminal)

5. Type in “sudo –s”

6. Next type “while sleep 1; do rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext; done”

7. Launch update, as usual update but don’t restart

8. in terminal press “CTRL + C” to end script

9. next type “nano /System/InstallAtStartup/scripts/1”

10. Replace the line Dont Steal Mac OS X.kext with dsmos.kext (at the last few lines in any) (I could not find these and did not carry out this step)

11. Exit editor and save

12. Reboot with update

13. You should now be able to check 'About this Mac' and see that it is at 10.5.6! You screed resolution will be lower but reinstalling the driver kexts will resolve this. (It was at this point that I found my keyboard was not working - I believe that a USB one would work but I simply used a combo of mouse and on screen keyboard)

14. Using OSX86 tools, download and install your drivers to take full advantage of them. (I skipped this part - instead reinstalling all of Paul's original driver Kexts using Kext Helper)

The usual caveats apply - just because it worked for me does not mean that I can guarantee it will work for you. Create a back-up and try - I've only been using OS X for about 2 weeks and I managed it so it can't be too difficult B)

Thanks for the update. I'll certainly give this a try when the 4211 arrives in the post tomorrow!

Ooph!

Each time I'm left without keyboard AND mouse! USB alternatives work fine, but until I can find some sure-fire kext files I think I'll be sticking with 10.5.5 this time.

Let's hope they roll out Snow Leopard soon, then there'll be no point in the 10.5.6 upgrade!

[Guest johnwin]

e=mc2 - I just reinstalled all 7 kexts from Paul's initial How To. No problems since.

If they don't work grab a copy of ApplePS2Controller.kext and try that. I didn't need it but I did a walk through upgrade with a friend of mine over IM this weekend and he needed to find alternate drivers and these worked.

Thanks. I'm going to order a spare HDD and clone this setup before I give it another go. I think I've installed OSX on this thing 5 times since buying it! Though I must admit each of those times I was probably being a little cocky. I'll let you know how I get on.

Woop. Gave it another try after sitting comfortably with 10.5.4 all this time, and it works. Keyboard and mouse died like last time, however a handy zip file containing the following 2 files installed using Kext Helper did the trick just fine:

ApplePS2Controller.kext

AppleACPIPlatform.kext

Courtesy of this place.

All I need to do now is install Paul's kexts, and get my life back on track!

I should also add that I installed 10.5.5 after a period of time using 10.5.4 and it refused to boot, so the only way I've managed to get it to work is a full clean install from 10.5.2 through 10.5.6.

As a prerequisite I backed up a few applications and the Library and Home folders onto an external HDD, which contained everything I could possibly need.

Good luck!
