LockDown Browser Mac Compatibility - macOS Versions + Apple Silicon (2026)

Last updated 2026-05-01 · LDBypass Editorial

LockDown Browser's Mac compatibility matrix changes twice per academic year on average: once with the September macOS release, once with the spring LDB catchup. The current production build (LDB 2.1.5.01) supports macOS Ventura 13, Sonoma 14, Sequoia 15, and is partially compatible with macOS Tahoe 26. Apple Silicon is fully native since LDB 2.0; only legacy 1.x requires Rosetta 2.

"Supported" means LDB launches and exams complete reliably across the LDBypass test fleet. "Partial" means LDB launches but exhibits documented bugs that have workarounds. "Unsupported" means LDB will not install or refuses to launch.

Apple Silicon (M1, M2, M3, M4) status

LockDown Browser 2.0+ ships as a Universal Binary. Native arm64 code paths run on every Apple Silicon Mac since the first M1. There is no "Mac with Apple Silicon" caveat for the 2.x family; all support comments below apply equally to M1, M2, M3, and M4.

The annual compatibility break cycle

Predictable seasonal pattern that recurs every year:

  1. June (WWDC). Apple announces next macOS major. Developer beta available; first beta often introduces TCC, WebKit, or sandboxing changes that break LDB.
  2. July. Respondus posts an advisory KB acknowledging the issue and noting production LDB is not yet supported on the beta.
  3. September. Apple ships public release. LDB still doesn't fully support it. 4-8 week window where exams break for early-upgrade students.
  4. October-December. Respondus ships updated LDB with fixes. Universities communicate the upgrade requirement.
  5. January-April. Spring semester runs cleanly until Apple ships a minor (15.x → 15.x+1) with TCC tweaks.
  6. May. Final exams happen. Compatibility issues spike right when students cannot afford them.

Practical advice every September: do not upgrade your Mac to a brand-new macOS major release if you have an exam in the next 4 weeks.
