iFreak-X Posted October 8, 2013 Share Posted October 8, 2013 Hey I successful installed the 10.9 GM on my Lenovo B570 using MyHack. Seems to run just fine, but the SpeedStep doesn't work. I have an SSDT for my CPU and SteedStep worked on 10.8 and 10.7. Problem is the new AICPUPM Kext which gives me a KP. Is there an patched Version for 10.9? Currently I have the patched AICPUPM of 10.8.5 but SpeedStep still doesn't work Hope you can help me Edit: I patched the 10.9GM AICPUPM with the Patch by el colignio and it worked Now SteepStep works fine like in ML and Lion. 1 Link to comment https://www.insanelymac.com/forum/topic/292524-need-help-with-speedstep/ Share on other sites More sharing options...
