# Keep Awake — Keep your Mac awake

Stop your Mac sleeping for an hour, until a time, or until you turn it off. Part of OneMacTools, 138 private tools in one native Mac app (macOS 26 or later); category: Utilities. Runs on your Mac; nothing is uploaded.

Choose how long — an hour, two, four, until a time or until you turn it off — and your Mac stays awake, with the display on too if you like. It turns itself off when the battery drops below 20% or the Mac runs hot, and the time left shows next to the menu bar icon.

## How to use it
1. **Choose how long.** Pick 1, 2 or 4 hours, Until a time (type something like 17:30 or 5:30 pm), or Until I turn it off.
2. **Choose about the display.** Turn on Keep the display on too if you're presenting or watching; otherwise the screen can still dim and sleep while the Mac stays awake.
3. **Click Keep Awake.** The time left appears next to the OneMacTools menu bar icon, with a cup.
4. **Turn it off when you're done.** Choose Turn off here, or Keep Awake › Turn Off in the menu bar. It also ends by itself at the time you chose.

## Options
- **For:** 1 hour, 2 hours, 4 hours, Until a time, Until I turn it off, or Turn off. A time that has already passed today means that time tomorrow.
- **Keep the display on too:** Stops the screen dimming and sleeping as well. Leave it off to save power when only the Mac needs to keep working, such as during a download.

## Tips
- Start it from the menu bar icon's Keep Awake menu for a quick hour or two without opening the window.
- Leave the display setting off for downloads and builds: the Mac keeps working with the screen asleep, which saves battery.
- It turns itself off below 20% battery so it never drains your Mac flat, and tells you when it does.
- Use the Keep Mac Awake action in Shortcuts to keep the Mac awake as part of an automation, for example while a long export runs.
- Mac Health's Awake tab shows anything else that's keeping your Mac awake.
