You would be surprised how many people make this mistake. Let me tell you a
story... I recently visited a scanner operator/designer that did the same
thing - use his monitor profile as a working space. The reason? He used the
Apple Calibration tool to create his monitor profile (in Mac OS X 10.2). If
he used any of the standard working spaces in PhotoShop, all of his images
had a horrible cast. So what he did was use his monitor profile as a working
space "because it was the only profile that looked OK". What he did not
realize was that he was effectively turning off RGB color management and
viewing raw device RGB. He did not even suspect that the monitor profile
that the Apple Display Calibrator created may be wrong. He would then
separate from the RGB monitor profile to a custom built CMYK profile for
their publication.
Apple should really, really explain that the Apple Display Calibrator is not
the best way to create monitor profiles. They should at least say that an
instrument should be used to calibrate monitors in a production environment.
I have not tried the Apple Calibrator for a little while so it may work
better now. The last time I tried it, it did not just create slightly
inaccurate profiles, it created completely wrong profiles - nothing like
what was entered in the UI.
John Gnaegy may want to respond to this. Am I wrong to criticize the Apple
Display Calibrator?

Not a good move; set it to a standard RGB space like AdobeRGB, and let

Photoshop convert on the fly to your monitor profile for viewing.
