Why would you patch Snow Leopard kernel to install Mavericks?

If you mean use a computer running SL to create the patched mach_kernel for Mavericks, then OK. But the kernel you are patching is the mach_kernel from Mavericks (on your USB).

The computer you use just has to be running OS X such that you can use Terminal and the perl scripts provided. Actually, you could probably patch in Linux if you could figure out how to write to an HFS+J volume.

mach_kernel from Mavericks (on my USB)? OK. Thank you for the hints. I'm going to search how to do it now. I will let you know the process

It's not working again.
I try this in terminal:
cp "/Volumes/USB/mach_kernel " "Volumes/MavricksHD"
then I download:
FakeSMC kext
NullCPUPowerManagement kext
still not working again

can you help me out?

Let's review the steps...

- create Unibeast USB
- patch mach_kernel on USB (now you have patched mach_kernel on USB)
- install OS X (using flags as appropriate)

Now you have vanilla mach_kernel on your HDD.

- boot back into the OS X installer
- use Terminal to copy patched mach_kernel from USB to HDD

------

Even if this is what you wanted to do (assuming you had already installed and were now copying from the USB to the HDD after a fresh install to HDD)

cp "/Volumes/USB/mach_kernel " "Volumes/MavricksHD"

... there are problems with the syntax. Should be:

cp "/Volumes/USB/mach_kernel" "/Volumes/MavricksHD"

the new code is not working either. I think I might need to recreate my bootable USB drive and install Mavricks again or intall Chameleon as boot loader

What step are you on?
