This is crazy ! My 2015 13 MBP retina screen was just flickering on and off and I couldn't do anything, everything froze. I had to hold down the power button for like 30 seconds before it shut off. What gives ? This is a brand new 1 month old Mac. Lol and it's ironic because I was watching a YouTube video and an advertisement for the new crappy looking Steve Jobs movie was playing when it happend.
