This works if you have access to the harddrive your installing on through a windows PC. I used this method to install onto an external HDD but it will also work if you are installing onto a separate internal HDD.

 

Thanks everyone for all those guides out there that got me installed - but, for me, none were as easy as this method - no terminal commands, no kext editing, no permission settings. Simple, straight forward install and upgrade.

 

 

1. Download and install MacDrive on windows

 

2. Boot IPC 10.5.6 install.

 

3. Choose the bare essential - no 3rd party applications, no ethernet/wireless/soundcard/video card options from customise menu.

 

DO CHOOSE your kernel, chipset and any relevant patches.

 

4. Run install.

 

5. Once successful, boot into MAC OSX to check install works. Boot into windows and access the drive you installed OSX on and make a backup of mach_kernel from the root (copy and paste onto windows desktop or something).

 

6. Download 10.5.7 combo update from the apple site and copy to MAC OSX install drive

 

7. Boot back into MAC OSX, run 10.5.7 combo update. Restart when done but BOOT BACK INTO WINDOWS

 

8. Go into the root of the mac osx install drive and delete mach_kernel and restore the one you backed up earlier.

 

9. Restart and let MAC boot. It wont boot first time, this is part of the update. Boot again with -f flag this time. It will boot.

 

10. For 10.5.8 repeat steps 6 to 9 (but obviously, download 10.5.8 combo update instead)

 

11. Download osx86tools and 10.5.5 version of seatbelt.kext. Using osx86tools, install seatbelt.kext. (This will stop OSX crashing when you loads a .dmg file)

 

Now search the internet for your drivers, install and you are done!

 

Vanilla kernel: I dont use vanilla kernel and I havent much knowledge on it. From what I have read though, if you use it you probably dont need to backup and restore your mach_kernel. The combo updates will install a new version of vanilla kernel - so if you use vanilla kernel, its worth trying to boot into OSX without restoring your orignal mach_kernel first.

If your hardware can use the vanilla kernel, there's no need to replace or backup the kernel when updating.

 

You can also skip the 10.5.7 update, go straight to 10.5.8 and skip the part about seatbelt.kext.

I am having issues trying to update from 10.5.6 to 10.5.8. I installed 10.5.0 retail vanilla kernal (I believe that is what it is). Whenever I go from 10.5.6 to 10.5.8 it just gives me a black screen. Below is my specs of my system.

 

Intel Core 2 Duo E8600

Gigabyte GA-EP45-DS3L

BFG Tech 9800GTX+ 1GB Vram

Dual Samsung DVD burners

1 TB Hitachi 3.0GB/sec 7200 RPM 32MB cache

 

I am not sure why it keeps breaking my setup. Any help anyone could provide would be most helpful.

 

Thanks,

Falcon060
