Disable Cmd-Opt-Escape on fullscreen app

Question

I am using:

    if (CGCaptureAllDisplays() != kCGErrorSuccess) {

To capture the display and secure my app while the user is away, but users have reported, and I have confirmed that pressing simply force quits my app.

How can I stop that behavior?

Answer 1

I believe what you want is a kiosk environment; see Apple's Technical Note TN2062: Creating Kiosks.

Specifically, you'll want to use -[NSApplication setPresentationOptions:]; see NSApplicationPresentationOptions here for possible values.
