I actually like that Apple no longer installs profiles for every monitor and
StyleWriter they ever made (yes, yes... that's an exaggeration). It
re-enforces the fact you're meant to create your own profiles for your
monitor and printer.
The profiles Apple installs with ColorSync has always been an issue. At
least they've got rid of the "useless" profiles. Whether Apple should
install common "working space"/"unity" profiles is a constant point of
discussion on this list.
Apple never has installed Adobe 98. You have to install an Adobe product to
get that, and I'm not even sure if Adobe installers put it in the ColorSync
Profiles folder anymore. I think its installed in the Application Support
folder.

I could never get PS to run in Classic under Mac OS X. None of the menus
work for me. You REALLY don't want to run ANYTHING in Classic if at all
possible. I would never rely on Classic to run anything critical. You only
run Classic as a last resort - eg to run an old app that you know won't be
updated. I would really wait until Adobe releases PS for X. I wont be
moving to X until then.

All profiles that can be used by ColorSync on Mac OS 9 should be able to be
used in X. Try adding the ".icc" extension to the file name of your profile
if ColorSync doesn't recognise them.
Because of the multi-user architecture of Mac OS X, profiles are stored in a
few different locations.
The system stores profiles in /System/Library/ColorSync/Profiles/. This is
where the "Generic" profiles live. Never put anything in here!
Profiles that are global (accessed by every user on that machine) are stored
in /Library/ColorSync/Profiles/. This is where I generally put my profiles.
I can't see much point having per-user profiles. But if you must...
You can also put profiles in your home folder in
~/Library/ColorSync/Profiles/. These can only be accessed by that user. I
think the only reason you'd use this folder is if you don't have permission
(folder rights) to put stuff in the global profiles folder.

As far as I know, no one has come out with a Mac OS X version of a monitor
calibrator. Optical, ColorBlind, and others run an app at startup time to
set your video card LUTs. I'm not sure whether this will work in X. I've
always wondered why these apps are needed. I always thought it was possible
to add a tag in your ICC profile that specifies video card LUTs that
ColorSync is meant to set... but maybe I'm wrong. I remember reading in
Prove It! about the "LUT Wars" but I can't remember what the issue was.
