CaffeinateCat v1.0.0
CaffeinateCat v1.0.0
A tiny macOS menu-bar app that keeps your Mac awake — even with the lid closed and unplugged. ☕️
Features
- Caffeinate — keeps the screen on and prevents idle sleep.
- Keep Awake When Lid Closed — keeps your Mac running with the lid shut, even on battery. Perfect for builds, servers, downloads, or coding agents while you travel.
- Timers — run either mode indefinitely or auto-off after 15m / 30m / 1h / 2h / a custom duration.
- Starts caffeinating automatically on launch, so it just works.
- One-time admin setup for the lid-closed feature — no developer account or manual config needed.
