Hi guys my rMBP 13" (October 2013) froze this morning while I was looking for a hard case on amazon. I could still put it into sleep mode with the power button but as when I turned it on again I couldnt put in my password since it was frozen. So I had to hold the power button to reboot my Mac. Now it's working fine again. Only happened once since I got it on Wednesday. Just seems odd was only using safari. Anyone had the some problem? Should I return it for a new one?
