Frequently Asked Questions

Everything you need to know about DontSleep

🔐 macOS says "DontSleep.app cannot be opened" - Is this safe?

Yes, DontSleep is completely safe! This security warning appears because we're an independent developer who doesn't pay Apple's $99/year certificate fee. The app is 100% open source - you can review every line of code on GitHub.

Quick Fix (30 seconds):

  1. Open Terminal (Applications → Utilities → Terminal)
  2. Paste this command: xattr -dr com.apple.quarantine /Applications/DontSleep.app
  3. Press Enter
  4. Double-click DontSleep.app to open it

Alternative: Right-click the app → "Open" → "Open" (sometimes works)

💰 Is DontSleep really free?

Yes, 100% free forever! DontSleep is open source software with no hidden costs, subscriptions, or premium features. We believe essential Mac utilities should be free for everyone.

The security warning you might see is simply because we choose not to pay Apple's $99/year developer certificate fee. This keeps the app completely free for users like you.

🌙 How do I use DontSleep?

After installation, look for the DontSleep icon in your menu bar (top-right of your screen). Click it to toggle sleep prevention on/off:

  • 🌙 Moon icon: Sleep prevention is OFF (normal behavior)
  • ☀️ Sun icon: Sleep prevention is ON (Mac stays awake)

You can also access settings by clicking the icon and selecting "Settings" to configure launch at startup and other preferences.

🔒 Does DontSleep collect my data?

No, absolutely not! DontSleep is a local-only app that doesn't collect, store, or transmit any personal data. It only uses macOS system APIs to prevent sleep - nothing more, nothing less.

Your privacy is important to us. The app works entirely offline and never connects to the internet.
