Just got my new Space Gray rMB base model yesterday. Messed around with it for a few hours last night. Just tried to use it now and the keys won't light up. I press the buttons to turn up the illumination and it shows a circle with an X light I have it on the lowest setting. This happens no matter if I press up or down on the illumination. I Googled and saw something about resetting the SMC and I tried to do it but no luck. Well tried the best I could on the new MacBook since the directions were all for MBA or MBP. Any suggestions?
