I was just looking the system over yesterday and it seems to be running a little hot. I noticed that the Processor info is gone from About This Mac. I have an i5-5300U proc, realtek alc3234/3, and Intel USB 3.0 extensible host controller. Should I use the Realtec kexts from HVT? Where can I get support for the CPU and USB 3.0? Is there anything else I'm missing? Do I need drivers for the free-fall sensor, etc?
