Hi all, I’m working an a display for an exhibit, we want to display an interactive website on a monitor. The monitor will be hooked up to a Mac that has Yosemite, it’s an older Mac so it can’t be upgraded. We want to remove the ability to access other sites so that the viewer can only visit the site we want them to see. How can we lock the Mac down to one specific website? Thanks so much for any advice you have.
