Our employees are logging into our shared computer using Guest user.
At some point somebody will click on an email address and Mail.app will open. If they put in their Gmail credentials, then it will download GBs of mail onto the computer. This will be deleted later, which is cool, but this whole process can be avoided.
How do I restrict Mail.app from opening in Guest user?
Also, it would be nice if I can restrict access to Facebook and other such websites that we don't want employees to browse.
