2013 Mac Pro owners, I've noticed two very minor things about my system and I am wondering if you're experiencing the same: 1. The power cable doesn't fit snug into my Mac Pro. The right side sticks out a bit, while the left side is perfectly flush. I haven't experienced any issues with this, but I still found it odd — especially considering how careful Apple usually is with small details. 2. If I listen very closely to my Mac Pro, I can hear a faint static-like sound. Is this normal? It's the kind of sound that's only audible if you're really listening for it. Because I'm still going through my "new shiny toy" phase, I can't help but point it out. Also, just as a note, my second point isn't in reference to the high pitch noise that others have apparently been hearing. Mine is very low and probably normal. However, because the fan is the only moving part, I want to be sure. Can you do me a favor and see if you can hear anything with your Mac Pro? Thanks in advance!
