Respondus LockDown Browser on Mac Complete Guide

LockDown Browser on Mac uses a combination of kiosk mode and screen monitoring to enforce exam integrity.

System-level private windows those with a system-level privacy flag remain invisible to these APIs. Fracture provides an AI overlay alongside LockDown Browser without any conflicts.
