I must say I have been on a winning streak with my rMBP - never froze on me for an entire year since I got it! But looks like my luck ran out today when I was running my Splashtop Remote Desktop program and the system froze up. Not worked except the mouse. I tried Force Quit and everything - nothing happened. So I had to do my last resort - hold down the Power Button. Shutdown and back on. Back in the day - people used to worry these forced shutdowns messed up the HDD, but since all rMBP use SDD to begin with - should I be concerned of some hardware being damaged from this occurrence?
