It seems to me that most photographers are using film that is balanced for Tungsten
(indoor) lighting, which is much cooler on the Kelvin scale then daylight. The
Mac screen (like most other CRTs), has a much 'warmer' color temperature (the
white has more 'red' in it.) If photographers used film balanced for daylight,
the mac screen would show up much closer to the white that appears to the human
eye. But then, photographers would have to use lighting in their studios that
was corrected to produce a higher Kelvin temperature (a 'warmer' white); it
amounts to putting a filter on _all_ of the lighting, or using other types of
lighting which produce a higher color temperature, more comparible with daylight
at 12 noon.
  
Over the years, it seems that folks have come to 'expect' to see the Mac screen
appearing 'blueish' in color print ads. I can see no real reason for Mac screens
to appear Blue in color photographs other then the reasons I mentioned above.
(BTW, the same things apply to video... Check out some commercials)
