How to Keep Your Mac’s Screen On During Important Tasks

Having your Mac screen shut off during an important task just because you haven’t touched your keyboard or mouse in a while can be annoying, but completely turning off sleep mode results in more power use and excessive wear and tear on your system. If you just want to make sure your Mac screen doesn’t turn off during important tasks, you can do so using aterminal command .

Here’s how to keep your Mac screen on using a terminal command:

1. Open the macOS Terminal app .
   Type Terminal intoSpotlight , or open it in the Finder viaApplications >Utilities >Terminal .
2. Typecaffeinate .
   
3. PressEnter .
   
4. Your Mac screen will stay as long as the Terminal window remains open.
5. To disable caffeinated mode, clickTerminate on the alert that appears when you attempt to close the Terminal window.
   
6. After successfully closing the Terminal window, your Mac will once again enter sleep mode according to your Energy Saver settings.

Why Your Mac Automatically Goes to Sleep

Your Mac automatically goes to sleep to save power for both environmental and cost-saving reasons. The automatic sleep timer is on by default, so your Mac will automatically go to sleep if it doesn’t receive any inputs for a few minutes unless you change your Energy Saver settings. Sleep Mode is supposed to be disabled whenever you’re watching or listening to media, but that isn’t always the case.

If you find that your Mac automatically goes to sleep when you’re watching movies or listening to music, then you may want to use the method described above to increase the amount of time before sleep mode engages or turn the automatic sleep feature altogether.

How to Schedule a Mac to Sleep Automatically

While your Mac is designed to sleep automatically whenever you aren’t using it, you can also schedule your Mac to automatically sleep at specific intervals if you like. This is useful if you want to fully disable the automatic sleep feature but still have the Mac enter sleep mode during times of the day when you normally aren’t using it, like when you’re sleeping at night.
