E6440 with Core i7 Issues


Recommended Posts

After several attempts at getting OS X 10.9.5 to Install on my machine, I successfully installed the software with only a few glitches. 


I couldn't find any support files to get my Core i7 4600m Haswell CPU working properly.  From HW Monitor, only 2 of the spped step setting are working.  Any suggestions?


Also, I noticed that my sound is not working and I'm not sure if the Intel HD 4600 Graphics is working properly.
