How to Use ChatGPT on a Locked-Down Mac (LockDown Browser, Examplify)
When your Mac is locked down by Respondus LockDown Browser, Examplify, or another proctor app, you cannot Cmd-Tab to a regular Safari with ChatGPT open. The Fracture overlay provides the path: an invisible window that loads chat.openai.com alongside the proctor.
The lockdown apps disable Cmd-Tab and Mission Control to prevent app switching. They do not (and cannot) prevent a window that the macOS window-privacy API is hiding from them. Fracture marks its window private; the lockdown app does not see it in the window list, cannot capture it in screenshots, cannot stream it over screen-share. You sign into ChatGPT once before the exam, leave the session active, and toggle with ⌥⇧H during the locked session.
No. The web session persists. You sign in once and the cookies stay valid through the exam.
Some aggressive proctors do. Use Ollama locally instead - see our Ollama exam guide.
Yes, perfectly. The overlay is universal binary and Apple Silicon native.
Need reference access during your exam?
Fracture runs a native floating overlay that sets the macOS window privacy flag. It is 100% excluded from screen capture feeds, window lists, and proctor recordings.
