Hi folks, I just got the 13" late 2013 rMBP yesterday. Almost all is well, except the backlit keyboard. It flickers. Like every 5-10 seconds, it "flashes" once for a nanosecond, like lights going on/off very quickly. In attempt to fix this, I on/off the auto adjust keyboard lighting setting in preferences. No fix. I then talked to AppleCare and they asked me to reset PRAM (no fix) and then SMC. SMC fixed it for a while, but now the problem is back. I think it's somehow driver / software related because SMC reset fixed it for a while. Is anyone else seeing this?
