Edit:The fix to the missing kernel is already listed in the guide above.

My guess is that you selected Laptop support, as I had the same issue. Be patient, and wait until later today for Unibeast 5.0.1 to fix this issue, or if you're really impatient, you can go into your unibeast created drive, go to Extra/org.chameleon.Boot.plist, and remove these two lines:

[COLOR=#000000]<key>Kernel</key>[/COLOR]
[COLOR=#000000]<string>mach_kernel</string>[/COLOR]

Or change the string to the correct directory, like so:

[COLOR=#000000]<key>Kernel</key>[/COLOR]
[COLOR=#000000]<string>[/COLOR][COLOR=#000000]/System/Library/Kernels/kernel[/COLOR][COLOR=#000000]</string>[/COLOR]

Make sure you follow letter casing as well.

I really suggest you wait instead, and let Tony and MacMan release an updated one we know will work.

Ok thanks... ill wait!

also i didnt select laptop support!!

and that line of code is not in my unibeast file!

Is there really supposed to be a release of UniBeast 5.0.1 later today, or is this how rumors start?
