Macbook pro keeps freezing
I just got a brand-new mid-2014 Macbook pro. There have now been 2-3 instances where the computer freezes. The screen is unchanged and unresponsive to any trackpad or keyboard input. Have tried command-period, option-command-escape with no luck. Only holding down the power button and restarting it gets it out of this state. I am running OS 10.10.2. Any ideas?
MacBook Pro with Retina display, OS X Yosemite (10.10.2)
