I'm setting up a Mac lab in a high school. I need to limit the applications that students can access so they don't have access to system preferences. As soon as I turn on the "Limit Applications" feature in the account preferences none of the CS6 apps will work. I get a "don't have permission" error and then login with the admin user/password to "always allow" the program to run. It still doesn't work. Any idea where I can go from here?
