Hi Matt,
Sorry for the slow reply-- busy time of year!
I've setup calibrated labs under Tiger, Leopard, and Snow Leopard. Tiger was
simplest (and perhaps didn't have his problem), but none of my labs use it
any more. For practical purposes Leopard and Snow Leopard function about the
same in my experience. Other particulars depend on what kind of network
accounts and options your school uses (Active Directory, Open Directory,
Network Home Directories, and so on).
The simplest scenario is multiple local accounts on a single workstation or
basic network accounts on identical cloned workstations. (The behavior is
essentially the same.) Here goes:
1) Get the Mac calibrated, and name the calibrated profile something obvious
and purposeful like, "Calibrated iMac A1." The profile name should (of
course) be machine specific (A1 in my example) but not include any date
info-- because once you have it setup you will update the calibration to a
profile of the same name, and all users, even newly created users, will
still get the correct (and updated) monitor profile.
2) If necessary move the profile to Macintosh HD>Library>ColorSync>Profiles.
(You could put it into Profiles>Displays, but it's not necessary, and I
don't recommend it.) For simplicity and clarity delete any copies of the
calibrated display profile that may exist in any other location like the
Users Library.
3) Be sure that permissions are set to read & write for all users and
groups.
4) Now go into System Prefs>Displays>Color and reset the profile to the
calibrated one you just made and moved.
5) To facilitate easy testing go to System Prefs>Accounts and enable the
built-in Guest account.
6) Logout.
7) Login as root user (assuming you have enabled root). Navigate to
Macintosh HD>System>Library>/User Template/English.lproj. Copy the ByHost
folder from the admin user's Library>Preferences folder to the corresponding
folder in English.lproj.
8) It's probably not necessary, but I also copy
com.apple.systempreferences.plist from the user's Library>Preferences folder
to the corresponding folder in English.lproj.
9) Logout. Login as guest. Go to System Preferences>Displays>Color to verify
that it is set to the correct calibrated profile.
It think that should be all right and accurate, but I mostly wrote it from
memory, so let me know if anything doesn't work or make sense.
