LockDown Browser on M2 Mac (M2, Pro, Max, Ultra) - Compatibility 2026
The M2 family (M2, M2 Pro, M2 Max, M2 Ultra, released June 2022 - June 2023) is fully native on LockDown Browser 2.x. Slightly faster than M1 across the board with better battery efficiency. M2 Air 16 GB is the LDBypass test fleet baseline.

Performance on this chip
From our benchmark:
- M2 Air 16 GB: ~17% sustained CPU, ~10% battery / hour, 14s launch.

~5-10% improvement vs equivalent M1 chips on identical workload.
Compatibility notes
- M2 Air 8 GB: same OOM concern as M1 Air 8 GB on long Monitor-enabled exams. Recommend 16 GB.
- M2 Mac mini (2023): solid choice for desk setups. Fanless variants don't exist; the Mac mini has active cooling.
- 15" MacBook Air (2023, M2): same M2 chip but larger battery - comfortable for 3-hour exams.
Recommendations
If you're on M2 / M2 Pro / M2 Max / M2 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
Is M2 Air 16 GB enough for any exam length?
Yes - verified across the LDBypass test fleet on exams up to 3 hours with Monitor enabled. 16 GB is the practical floor; 24 GB+ doesn't materially help LDB.
Should I buy M2 or wait for M3/M4?
For LDB alone, M2 is sufficient. M3/M4 helps with other workloads (video editing, ML, parallel compilation). LDB doesn't exploit the wider cores.
