Americano — Keep your Mac Awake

Americano prevents your Mac from sleeping and (optionally) keeps the display awake. It’s a small, focused menu bar app in the spirit of Caffeine/Lungo.

Requirements

• macOS 14 or newer
• Xcode 15 or newer

Features

• Menu bar toggle: Keep Awake on/off.
• Presets: Start for 10m, 30m, 1h, 2h, 5h, or indefinitely.
• Start Default: uses your chosen default duration.
• Allow display to sleep while keeping the Mac awake (Advanced).
• Activate at app launch (General).
• Deactivate when switching to battery (Advanced, opt‑in).
• Shortcuts support (Toggle, Activate, Activate for minutes, Deactivate).
• Single instance only (prevents launching multiple copies).

Settings

• General
  • Launch at login
  • Activate at launch
• Advanced
  • Default duration
  • Allow display to sleep while keeping computer awake
  • Deactivate when switching to battery

Build & Run

1. Open Americano.xcodeproj in Xcode.
2. Select the Americano scheme and Run.

Notes

• Americano runs as a menu bar app (LSUIElement=1). Use the cup icon in the menu bar to control it.
• Sleep prevention uses IOKit power assertions: NoDisplaySleep (keeps screen on) or NoIdleSleep (allows screen sleep), based on the Advanced setting.
