Hey guys, So I've been having this issue lately and I can't find a fix for it myself. I own a late 2013 MBP 13" with retina display and every minute or so the screen turns black for a split second and then returns back to normal. My macbook still runs fine before and afterwards but it's just annoying (and worrying!) that something's probably happening and I have no idea what it can be. Is anyone experiencing the same issue? Or does anyone know how to fix? Thanks in advance!
