Honorlock vs LockDown Browser on Mac (2026 Student Comparison)
Architecture comparison
| Aspect | Honorlock | LockDown Browser |
|---|---|---|
| Install path | Chrome extension (~10 MB) | Native macOS app (~95 MB) |
| Where exam runs | Inside Chrome tab | Inside dedicated kiosk-mode app |
| Apple Silicon | N/A - Chrome handles it | Native arm64 since LDB 2.0 |
| Admin password to install | No | Yes (Sonoma 14.4+) |
| Persists after exam | Extension stays in Chrome | App stays in /Applications |
| Uninstall | Remove Chrome extension | Manual uninstall (see our guide) |
Privacy comparison
| Capability | Honorlock | LDB + Monitor |
|---|---|---|
| Webcam recording | Yes (during exam) | Yes (during exam) |
| Microphone | Yes | Yes |
| Screen recording | Yes (Chrome tab + active window) | Yes (full screen) |
| Phone detection (audio analysis) | Yes (AI) | Limited |
| Second-person detection | Yes (heavy AI) | Yes (lighter) |
| Behavioral AI flagging | Heavy | Lighter |
| Retention default | Variable (institution-set) | 5 years |
Performance on Mac (M2 Air baseline, 90-min exam)
- Honorlock: dominated by Chrome's overhead (~620 MB Chrome + extension). Battery ~16%/hr (mostly Chrome). CPU ~12% sustained.
- LDB + Monitor: ~720 MB self-contained. Battery ~10%/hr. CPU ~17% sustained.
Honorlock's battery cost is higher because Chrome is the dominant consumer; LDB's self-contained approach is more efficient overall but uses more RAM.
Accessibility
Both have documented disparate accuracy on darker skin tones in academic studies. Honorlock's heavier AI usage means more behavioral flags overall, which can over-flag students with disabilities or non-typical study habits.
Student experience
| Aspect | Honorlock | LDB |
|---|---|---|
| Install friction | Lower (extension only) | Higher (full install) |
| Pre-exam setup | ~5 min (extension consent) | ~15 min (with Monitor system check) |
| Mid-exam stability | Chrome tab can be flaky | Kiosk mode is stable |
| Network requirement | Continuous (Chrome-based) | Continuous (LMS + Monitor upload) |
| If something breaks | Tab crashes; restart Chrome | Force-quit + reinstall procedure |
Which is "better"?
For a Mac student:
- If install friction is your top concern: Honorlock (extension is faster).
- If stability is your top concern: LDB (kiosk mode is more deterministic).
- If privacy is your top concern: Both invasive when recording; LDB-only mode (no Monitor) is the least invasive.
- If battery is your top concern: LDB + Monitor edges out Honorlock.
- If you have an exam tomorrow and have neither installed: Honorlock is faster to set up.
What your university uses
Universities standardize on one or the other (rarely both). Check your course's syllabus or LMS for the requirement. Don't install the wrong one - they don't interoperate.
Frequently asked questions
Can I use both LDB and Honorlock if my courses use different ones?
Yes - they don't conflict. LDB is a separate native app; Honorlock is a Chrome extension. Each only activates when its corresponding course exam launches.
Which has better Mac support?
LDB has dedicated Mac engineering. Honorlock is browser-based, so its Mac support is essentially Chrome's Mac support. Both work on current macOS.
Can Honorlock detect virtual machines?
It tries via behavioral signals + browser fingerprinting. Less aggressive than LDB's explicit hypervisor detection. Both can detect VMs in most cases.
Does Honorlock work on Safari?
Some versions support Safari. Most institutions deploy Chrome-only. Check with your university IT.
