Steps to reproduce the problem: 1. Add relevant GeneratePStates and GenerateCStates lines to boot.plist 2. Reboot 3. sysctl -a |grep cpufrequency 4. cpufrequency_max and _min are the same as _current. Expected result: Working Speedstepping Actual result: Non-working Speedstepping. Other Notes: If i use VoodooPStates.kext instead of the above lines, Speedstepping works, and sysctl shows 2.0/2.33/2.66GHz pstates.

Same result on a MacBookPro: hw.cpufrequency = 2400000000 hw.cpufrequency: 2400000000 hw.cpufrequency_min: 2400000000 hw.cpufrequency_max: 2400000000 This is totally normal, check out voltage, temp and frequency with fakesmc monitors. http://www.projectosx.com/forum/index.php?showtopic=1206

until there is posted proof of cstates/pstates not working this is going to be closed. proof consist\s of dumps of your ssdt tables and ioreg and bdmesg of booting w/ cstate/pstate gen = yes an dwithout and without but + pstate.kext.
