Control Your Mac's Display Settings
Whether you are running macOS Ventura, Sonoma, or an older version, Apple's display settings are aggressive when it comes to saving power. The screen will quickly dim and turn off if you aren't actively swiping on the trackpad or typing.
If you are following a recipe, reading sheet music, or analyzing data, a dark screen is incredibly disruptive. Instead of constantly swiping your trackpad or altering your global System Settings, use our tool to stop the macOS screen from turning off. It runs temporarily in a browser tab, keeping the screen on only when you need it, and returning to normal power-saving mode the moment you close the tab.
Keep Your Display On in 3 Steps
1. Open the Web Utility
Navigate to the tool using Safari, Chrome, or Firefox on your Mac.
2. Initiate Display Lock
Hit start. The utility requests a continuous display state from macOS, overriding the auto-dim feature.
3. Close Tab to Stop
When you are done reading or rendering, simply close the browser tab. macOS will instantly revert to its normal sleep schedule.
macOS Display FAQs
Is this better than changing my settings in System Preferences?
Yes, because it is temporary. If you change your global settings to 'Never Sleep', you might forget to change them back, risking screen burn-in and battery drain. This tool only runs when the tab is open.
Does it stop the macOS screensaver from starting?
Absolutely. By keeping the display active, it prevents the system idle timer from triggering the screensaver.
Can I use this on an iPad via Safari?
Yes! Because it relies on standard web APIs, it works to keep iPadOS screens awake just as effectively as macOS.
