LockDown Browser
LockDown Browser is a specialized exam browser for macOS that schools use to deliver online tests in a controlled testing environment.
What is LockDown Browser?
LockDown Browser is a secure testing browser for macOS that helps schools and universities deliver online exams with restrictions that are not present in a regular web browser. It is used by students when an assessment in a learning management system requires a locked testing environment, and it is commonly paired with institution-specific download links and course workflows. The app opens quizzes and tests in a controlled session, limits switching to other applications during the exam, and supports common learning platforms used in education. In some courses it also works with Respondus Monitor for webcam checks and remote proctoring steps before an exam begins. LockDown Browser includes student help and system checks that can be used to confirm device readiness before a test. Respondus publishes the software for use on Mac and other supported platforms in academic testing environments.

Safety overview
Status: Use with caution
LockDown Browser is legitimate academic testing software, but it is designed to restrict normal computer use during an exam and may require access to the camera when a course also uses Respondus Monitor. Those controls are expected for proctored testing, yet they are more restrictive than a normal browser session. Keep it only if your school requires it, close unrelated apps before use, and review webcam or privacy prompts carefully so you understand what an exam session will use.
Recommendation: Keep LockDown Browser if you actively take exams that require it. If you have finished the course or no longer need proctored online testing on this Mac, you can remove it without affecting normal web browsing in other apps.
