1. Amphetamine
Free Mac App Store utility that keeps a Mac and its displays awake, with timers, Triggers, Closed-Display Mode and optional cursor movement.
- Runs on
- macOS 10.13 or later (Mac App Store)
- Keeps Teams or Slack Available
- Not claimed. Its listing offers periodic cursor movement but does not mention Teams or Slack, so its site does not say whether it keeps Teams Available.
- Laptop closed
- Its Closed-Display Mode can keep a supported MacBook awake with the lid closed. Power Protect addresses external-power changes on Apple Silicon; the Mac must remain on.
- Price
- Free
Why it fits: Amphetamine is free, runs on macOS 10.13 or later, and documents Closed-Display Mode for keeping a supported MacBook awake with the lid closed.
Watch out: Its last Mac App Store update was November 10, 2023; Power Protect addresses external-power changes on Apple Silicon, and closed-display sessions can work without it.
