I was wondering if anyone had similar problems with their MacBook Pro Retinas, I have the 2.3Ghz config. Since using it for two months, I have gotten a random screen shutoff three times. I had to do a hard reset in every case. Also when waking up from sleep, the keyboard and mouse would not respond for about 20-30 seconds and finally it will start working. Yes I did install the SMC update, anyone know what's going on here?
