Hi,

I have noticed that IntelCPUPMDisabler.kext was not needed and useless to fix the sleep problem.

- Please delete it from your Extensions folder if you have installed it.

- Remove the rc.wakeup sleep fix script

- Update the rc.sleep sleep fix script with the new one available here: Sleep_10.5.8_sleep.txt
