Under OS 10.2 Apple applications such as Mail and Preview are color
managed. I don't think it follows that all windows on a 10.2 machine
are color managed.
Actually they appear to be, based on information I've gathered thus
far. The exceptions to color management in OS X are:
1. There is an API Apple offers to developers to essentially exempt
content from being color managed.
2. If the source and destination are the same. So for on-screen
purposes, this means the source profile of the window is the same as
the display profile.
Currently, anything not a PDF that is untagged has the display profile
assumed. My understanding is this is temporary, eventually all untagged
content will have a source profile per the RGB, CMYK and Gray default
settings in the ColorSync panel. Effectively this will give us a system
wide working space - very cool. Any PDF that is untagged currently has
the Generic RGB profile assumed.
ID201 on OS 10.2 works as ID201 on OS 9.1:
Unchecking the Edit > Color Settings > Enable Color Management option
tells InDesign not to apply the RGB working space to monitor space
transform for the saturated blue object I have drawn and the color
changes as it should.
PostScript output generated by applications themselves is left
untouched by Mac OS X. So only application color management will affect
the output of these applications when PostScript is used.
