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

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.
