I can't copy the preference file because when i look in it if find the reference of user folder on disk.
On Mac OSX 10.6.8 the Color Settings seem to be stored in
~/Library/Preferences/Adobe Photoshop CS6 Settings/Color Settings.csf
I would not necessarily recommend duplicating that, though, but would rather save a csf-file and transfer and load that at the various stations.
Maybe with a java script?
One can set the Color Settings and also (many of the) Preferences via a Script.
And i have to send it to 50 users.
Do you not have physical acces to the machines?
