I just upgraded to 10.6.2, and I cannot calibrate my iMac any longer.
When I get to the luminosity adjustment, it tells me my iMac display (same setting I had) only has 58 cd2. Even when I crank it up to maximum (unuseably bright), I only get to 80 cd2.
I downloaded the newest iMatch 3.6.2 software.
I have a long line of jobs and cannot afford not to work. Any advice would be appreciated why Snow Leopard topedoes screen calibration on a 24" white iMac.
