Do as the title suggests. The major one that I have encountered: Audio drivers. Here is my situation. I boot up my MBP, its great. Then I hook it up to my desk (with 3.5mm audio included). I turn up the volume and I hear some sort of clicking... I can't really explain it. I unplug the speakers, and the issue persists. The only way to fix it is to reboot. I will take a recording of the audio soon. Other issue: Sometimes the ambient light sensor doesn't work, and I have to force the keyboard backlight with Lab Tick.
