About:
Red Eye is a lightweight utility that keeps your Mac awake by preventing it from entering sleep mode. It runs quietly in the menu bar, offering a simple toggle to override system power management settings. This tool is ideal for users who need to ensure long-running tasks or downloads are not interrupted by system sleep.
Key Features:
  • Menu bar interface for easy access
  • Prevents system sleep without altering energy saver settings
  • Lightweight and unobtrusive background operation
  • Simple on/off toggle for quick activation
Use Cases:
  • Preventing sleep during large file downloads or uploads
  • Keeping the system awake for long-running terminal processes
  • Maintaining display wakefulness for presentations or demos
Alternatives:
  • Amphetamine – More feature-rich with complex rules and triggers, while Red Eye focuses on simplicity
  • caffeinate (CLI) – Built-in macOS command-line tool, but lacks a persistent GUI menu bar interface
