It has done so, and lied, since 10.0. Apps must be specifically written
to use these settings, and only a handful do. Apple's don't.
And then I open an untagged image in Preview and then save, it ignores
the
above and still the image remains without embedded profile. Same with
iPhoto. To what extent and which app then does this feature in the CS

have any effect? Id love to know.
Some scanner and digital camera packages look for those settings, and
Adobe applications, when you specifically set them to use those
settings.
Preview is a fundamentally broken application when it comes to color
management. It also converts images without warning when there is an
embedded profile. It assumes Monitor RGB as source. When you export
files, depending on the format, they will get either no profile,
Generic RGB, or sRGB embedded. It's really a train wreck of an
application - from a managed color point of view.
2. Editing images (conversion from embedded source to Generic RGB as
destination, retagging with Generic RGB).
This is what Im getting in iPhoto. Its dangerous! And no warning
too..thats
the best bit.
A warning would confuse the target end user: the one who doesn't know
anything about color management, and probably doesn't want to know. You
are too sophisticated of a user for this application. And what sucks is
that the app is so frigging cool that it is appealing to prosumer and
professional users. But if they use it, there is a good chance they're
going to get bit.
Its such a shame to have a feature like this that ends up being near
useless
Youd think it would be such an easy thing to do incorporating a few
more
controls in iPhoto so you could print converting to destination
profiles and
being able to choose rendering intent. Even having an expert controls
box so
not to frighten some folk.
Color management doesn't have to be complex to work correctly, and it
certainly doesn't have to act stupid to be useful for experts and
non-experts alike.
