Not really possible - the user owns their own computer, they can do with them as they wish. However, there are ways to hide a setting so that it's harder to find. An easy-ish solution is to use CFPreferences in the 'by host' domain. It's not very hidden, but slightly more so than the normal user defaults. You can also write a value to a file in all sorts of locations (notwithstanding what sandbox might have to say about it) but a determined user can always find it and delete it. This is right and proper - as a user I have every right to know exactly what my computer is doing, and no part of it should be hidden or inaccessible from me. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
