If you are using SafeExam Browser (SEB) on a Mac, you may receive a red error screen that says, "SEB is Locked!" You can solve this issue by restarting your computer.

Error Message:

The image is a screenshot that is mostly a bright red screen with "SEB is Locked! System security feature is disabled. Enable System security feature and restart SEB," in white text. There is a large white textbox in the middle of the screen that shows a date and time in black text and "System security feature is disabled!" in bold, black text. There is a button underneath the textbox that says "Quit" in bold, black text.
