Display a webpage in Mac lock screen I want to leave my Mac locked, but display a web page (representing a web-based dashboard) in the lock screen. The idea is to leave this web dashboard showing 24x7 but without letting anyone else get access to the rest of the system.
You can download this screensaver which allows you to specify the site you want to display (found there).
Turn on the password to make your screensaver to be the lock screen:


Open "System Preferences"
Go to "Security &amp; Privacy"





Check "Require password [immediatly] after sleep or screensaver begins"
