On Mac computers, all browsers will automatically disallow pop-ups in full-screen mode and, thus, will not allow the launch of an exam. This is true regardless of whether or not pop-up blockers have been successfully disabled.
If pop-ups are being blocked, an icon generally appears in the address bar to indicate that a pop-up is being blocked; it will look like a little window. Click the icon and select "Allow pop-ups from" this site.
You can also do this in advance by using the Settings > Advanced > Content Settings menu in Chrome, or Preferences > Privacy & Security > Permissions menu in Firefox.
If the browser is NOT running in full-screen mode, and pop-up blockers have been successfully disabled, the exam will launch. Please have the student exit full-screen mode and refresh their screen. The warning message will disappear.
