Are you looking to change the dim time on your Mac? It’s an important setting to get right, as it not only helps with energy efficiency but also prevents screen burn-in. We’ll walk through the steps of how to adjust this setting, so you can get the most out of your Mac.

The dim time on your Mac is set in System Preferences and is found in the “Lock Screen” section. To access this, open System Preferences and then click “Lock Screen” in the sidebar. You may need to scroll down.

Once there, you can choose from a range of options for when the display should go to sleep. You can select anything from 1 minute to 3 hours or even “Never,” if you don’t want your display to ever turn off automatically. To make this change, simply click on the slider next to “Display sleep” and drag it to the right until you reach your desired timeout setting.

You may also want to adjust the brightness of your display manually. To do this, open System Preferences again and click “Displays” in the sidebar (you may need to scroll down). From there, you can drag the Brightness slider on the right-hand side until you reach your desired level of brightness.

Finally, if your Mac is running on battery power, you can control when it goes into sleep mode by adjusting a setting in Settings > Display & Brightness > Auto-Lock. Here you can choose when exactly your device should turn off its screen and lock itself for added security measures.

Adjusting these settings for your Mac isn’t too difficult and takes only a few minutes of your time! Hopefully this post was helpful in navigating how to change dim time on mac – happy adjusting!
