No description of Nullstack yet.
macOS has no built-in kiosk mode. There's no Guided Access and no Single App Mode, so locking a Mac to one website usually means expensive MDM or fiddly configuration profiles. Canned Web is the simple, native alternative. Enter a URL, hold ⌘⇧S, and the Mac is sealed fullscreen to that site....
