I am trying to calibrate my macbook pro with the spyder 5 elite and I am trying to follow Damien's instructions but when it comes to the brightness setting I don't have the Adjust option, it gives me 80, 90, 100, 120, 160, 180, do not adjust, or other option. What should i do? Also no room light option.... i was scared to calibrate and now i know why.. i feel like i am already messing this up!!
