    I have a 2012 MBP and have just installed Mountain Lion on it.

    My issue is I prefer a gamma setting of 1.8, instead of the default 2.2. I created a custom profile and calibrated it without using expert mode. As soon as I click Next to advance to the final part of creating a profile, the screen defaults back to 2.2.

    I can continue on and save the new profile, but clicking to switch between Color LCD and Custom LCD produces no change, in effect, it stays at 2.2 no matter what I do. I have tried deleting and re-creating the profile, tried restarting, but have not come up with a solution to this problem.

    Any recommendations?
