# Anti-Sleep (macOS caffeinate) ## When to Use - Use when the user wants the Mac to stay awake during a long supervised task. - Use when a build, download, or automation run should not be interrupted by sleep. Keep the Mac awake using the built-in `caffeinate` command. No install needed. ## Quick start — the standard command ```bash caffeinate -d -i -t 7200 # full power: screen stays on + no idle sleep, for 2 hours ``` Duration is `-t <seconds>`: 2h = 7200, 7h = 25200, overnight (9h) = 32400. ## Aggressiveness levels | Flags | Effect | |---|---| | `-i` | prevents idle **system** sleep only (screen may still dim/lock) | | `-d` | prevents **display** sleep (screen stays on) | | `-d -i` | **default choice** — screen on + system awake | | `-d -i -s` | adds `-s`: prevents sleep even on AC power semantics; `-s` only works when plugged in | | `-u -t 1` | simulates user activity — wakes the display right now | Default to `-d -i -t <seconds>` unless the user says otherwise. ## Tie to a process instead of a timer ```bash caffeinate -d -i -w <PID> # stays awake until that process exits (great for builds) caffeinate -i npm run build # wraps a command; exits when the command finishes ``` ## Run

caffeinate -d -i -t 7200    # full power: screen stays on + no idle sleep, for 2 hours
caffeinate -d -i -w <PID>          # stays awake until that process exits (great for builds)
caffeinate -i npm run build       # wraps a command; exits when the command finishes
