How to Keep Your iMac Screen On Without Sleep Mode

Share This:

The iMac is one of Apple’s flagship products, combining powerful hardware with a sleek design. But have you ever wanted to turn off the screen without putting your iMac to sleep? You can do this quite easily by using a few simple steps.

First, open the System Preferences on your iMac and select the “Energy Saver” section. Under the “Computer Sleep” setting, uncheck the box that says “Put the computer to sleep when it is inactive”. This will prevent your iMac from automatically going to sleep when you close the lid or after a certain period of inactivity.

Next, open up your Mac’s Display settings (this can be found in System Preferences or through Applications > Utilities). Here you will find an option titled “Turn Off Display After” which allows you to specify how long you want the display to remain on before it turns off. For example, if you want to keep your display on for an hour before it shuts off, set this option for 1 hour.

Finally, make sure that your Mac’s Screen Saver is disabled as this can interfere with turning off the display without sending your iMac into sleep mode. To do this, go back into System Preferences > Desktop & Screen Saver and make sure that None is selected under Screen Saver.

By following these simple steps, you can now turn off your iMac’s screen without it entering sleep mode. This feature can be useful for those who want their Macs to stay active while they are away from their desks but don’t want them running all night long. With just a few clicks of a mouse button and some basic configuration changes, you can now save energy while still keeping your Mac up and running!

When enabled, your Mac’s screen will automatically turn off after a certain amount of time has elapsed.

Night Shift allows you to set up custom schedules for when you want your display to be turned off or on.

Additionally, some Mac models have an ambient light sensor that dims your screen if the surrounding light dims.
