GRE At-Home Proctored Mac Setup

Updated October 2026 · 3 min read · Tested with LockDown Browser v2.1.6.01

GRE General Test At-Home is delivered through ETS using ProProctor (Prometric's home-proctoring product) on Mac. Live human proctor, continuous webcam, continuous screen capture.

ETS contracts with Prometric for at-home GRE delivery via ProProctor. ProProctor on Mac uses macOS' standard capture stack (ScreenCaptureKit), which honors per-window privacy. The overlay is technically invisible. Pre-exam: 360 room scan with phone, ID check, environment verification. During exam: continuous webcam, ambient audio, screen capture every few seconds, live proctor on call. The score cancellation risk for being caught using external resources is real - ETS does cancel scores and reports to programs.

About 1 hour 58 minutes for the General Test (shortened format since 2023).

No - ProProctor is a downloaded Mac app, not browser-based.

Only the on-screen whiteboard within ProProctor. Physical scratch paper is forbidden.

The Safe macOS Solution

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.
