Leopard 10.5.3 is out and ready for all mac users,

except for some of us Hackintosh users. Until now, a little script that makes 10.5.3 work!

Credit goes to netkas and iSkylla

Update 1: Getting Root Error Message, Probably means you have to revert to 10.5.2

Update 2: Ok the fix, It seems user, get an error message like this

what you need to do is backup your old IOAHCIFamily.kext and replace it with the new one

Ok first open terminal

sudo -s

*type password*

while sleep 1; do rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext; done

Open 10.5.3 Update Installer


Go back to your terminal and press Control C to end the script

In terminal type:

nano /System/InstallAtStartup/scripts/1

Replace the line Dont Steal Mac OS X.kext with dsmos.kext

Restart and boot with -v

It will start loading and then you will get the message MACH_REBOOT, there you can hard reboot your computer. When you reach the darwin boot screen again, boot with -v again just for safe measure and it will boot fine.
