I am setting up computers to run at a visitor centre, to be used by the public. I have been able to work out how to use Google Chrome in kiosk mode, but not a way for people to not be able to easily exit the application.
Is it possible to set up my Macs (running El Capitan, 10.11.6) to require a password to successfully exit an app? I am perfectly fine with a programming solution, but will need guidance in what to change, to what, and what the change implies. I can also settle for a solution specific for an Internet reader, but having something more general for an app would be preferable. A free method would be preferable, but we are open for considering paid options as well (we are considering eCrisper, but would like to explore other alternatives).
