LockDown Browser on M1 Mac (M1, Pro, Max, Ultra) - Full Compatibility
The original Apple Silicon family (M1, M1 Pro, M1 Max, M1 Ultra, released Nov 2020 - June 2022) is fully supported by LockDown Browser 2.x native arm64. Performance is equivalent to or faster than the Intel reference. Caveat: M1 Air 8 GB has reproducible OOM risk during Monitor-enabled exams >60 min - recommend 16 GB minimum.

Performance on this chip
From our benchmark:
- M1 Air (8 GB): ~22% sustained CPU on a 90-min Monitor-enabled exam. OOM-killed in 2/3 reproductions on long exams.
- M1 Air (16 GB): ~17% sustained CPU. No OOM observed.
- M1 Pro / Max: ~14% sustained CPU. Comfortable for any exam length.
- Battery: ~10-12% drain per hour on Air; ~7-8% on Pro/Max.
Compatibility notes
- M1 Air 8 GB is a known weak point for proctored exams > 60 min. If you have only 8 GB, plan around the OOM risk: charge fully, quit every other app, take exams < 60 min if possible.
- M1 Pro / Max / Ultra are oversized for LDB. The performance budget is comfortable.
- Battery life on M1 Air is strong baseline; LDB cuts effective battery by ~30%.
- Thermals: M1 Air (fanless) can hit thermal limits during very long Monitor recordings (3+ hours). Not a problem at typical exam length.
Recommendations
If you're on M1 / M1 Pro / M1 Max / M1 Ultra, the LDB experience is essentially identical to other Apple Silicon generations. Use LDB 2.1.5.01, run macOS Sonoma 14.6 or Sequoia 15.4 (latest stable), follow the standard pre-exam checklist.
Frequently asked questions
Should I upgrade my M1 Air 8 GB before next semester?
Recommended if you have proctored exams > 60 min. The 16 GB version of any M-series Mac comfortably handles Monitor without OOM risk.
Does M1 generation have any LDB-specific bugs?
No. Native arm64 since LDB 2.0. Behavior is functionally identical to M2/M3/M4 (with the noted RAM caveat).
Will Apple drop macOS support for M1 Macs soon?
M1 Macs are supported on Sequoia 15 and (likely) Tahoe 26. Apple's pattern suggests M1 will receive macOS updates through ~2027-2028.
