I compared AltTab, Mission Control, and Contexts across a dual‑monitor, keyboard‑first workflow on macOS. The focus: time to target window, accuracy, and how each handles many windows across multiple apps.
Quick Verdict (2026)
- Best for keyboard power users: AltTab—Windows‑style thumbnails, per‑monitor context, open‑source.
- Best built‑in overview: Mission Control—great mouse/trackpad overview, simple for casual users.
- Best search‑centric switcher: Contexts—fast type‑ahead selection; paid.
How I Tested (Environment & Method)
- Hardware/software: Apple Silicon Mac, 18GB RAM; macOS 26; dual monitors.
- Workload: 10–15 windows across VS Code, Chrome, Figma, Slack, iTerm2.
- Method: Repeated switches among a fixed set of windows; counted keystrokes/steps; timed target selection.
- Baseline: Native macOS App Switcher + Mission Control.
- Metrics: Time to target, mis‑switch frequency, and subjective friction.
AltTab reduced hunting via thumbnails and per‑monitor awareness; Contexts excelled when typing to filter; Mission Control was best for spatial overview.
