Share This:

If you’re a Mac user, you know the frustration of your screen going black at the worst possible moment. Whether it’s during an important presentation or while you’re working on an important document, it can be incredibly annoying and disruptive. Fortunately, there is a way to stop your Mac from going black—by disabling the screen timeout feature.

To do this, open System Preferences on your Mac by clicking the Apple logo on the top left of your screen. Once System Preferences is open, click on Battery. From there, select either Battery or Power Adapter and adjust the slider underneath “Turn display off after…” Drag the slider to Never to completely disable screen timeout.

Now that you have disabled screen timeout, your Mac will no longer turn off its display after a certain amount of time has passed. This will save you from having to constantly adjust your settings every time you want to keep your Mac awake for an extended period of time. It also means that you won’t have any more unexpected blackouts during important tasks!

We hope this guide has been helpful in showing you how to stop your Mac from going black with just a few clicks of your mouse. Remember, if you ever need to temporarily enable screen timeout again (perhaps because you want to save some battery life), simply go back into System Preferences > Battery and adjust the slider accordingly.

Now, go back to the main Settings menu and tap on System. Scroll down — there should be a new entry titled Developer Options.
