Hello, I've been successfully calibrating my macbook pro with a spyder 4 pro calibrator for 2 years. Apple replaced my video card this week and now it wont calibrate! It goes through the process, but the screen is still overly bright and cool when it is finished, nothing like my old dim warm look! When I compare calibrated to uncalibrated there is ZERO color change. I've tried recalibrating several times, resetting all the settings in spyder pro (in line with your instructiosn online - they had been reset to spyder factory), but nothing is working. I can go back to my last saved setting and it looks right but obviously I can't keep it set on the old one forever...
Thanks for your help.
