'Must Restart Error' during update 10.5.2 to 10.5.3. Now wont load

[David Alex]

Hey

 

I recently decided to update my mac from 10.5.1 as I few programmes I tried to use required the update.

 

I updated from 10.5.1 to 10.5.2 easily following a tutorial. I was following these steps.

 

1. Download the 10.5.2 Combo Update (search Google) 343MB
   
   
2. Go to /System/Library/Extensions/
   
3. Start Update
   
4. When AppleIntelCPUPowerManagement.kext apperars, move it to trash immediatly
   
5. The install finishes, but do NOT click the restartbutton!
   
6. Go to /System/InstallAtStartup/scripts/ and open the file 1 with a texteditor
   if you can’t access the folder
   • rightclick > Get Info
     
   • at the bottom of the window it says Sharing & Permission, unlock it and click the plusbutton
     
   • Select your Username, press Select and change your permissions to read & write
     

[*]Find the string /System/Library/Extensions/Dont Steal Mac OS X.kext and replace it with /System/Library/Extensions/dsmos.kext

[*]Save the file and restart

I tested the mac for a day and everything worked fine. I then decided to goto 10.5.3. The tutorial said it was fine to follow the same steps again and all should be dandy.

 

Shorly after following step 4 of the tutorial(moving kext file to the trash) the mac grey screened and told me I had to restart. With no other options I did.

 

Now it wont load, even in safe mode. It gets stuck on the white loading screen. It acts like its loading but nothing happens. I left it on for 4 hours and it stayed on that screen....

 

 

Im not really sure what my options are now. I dont want to format as I have tons of files on there I cant really loose. Has anyone had anything similar happen to them, or have any ideas I can try. I thought about possibly sticking in a boot disc and trying a repair? I'll probably give that a go tonight. But yeah, im not sure what to do as Im a bit a noob so any help would be much appreciated.

 

Thankyou
