When you don’t use your Mac for a little while, it’s possible for it to show a screen saver. This is meant to prevent any screen burn in that could occur if certain elements on the screen are displayed in the same location for too long.
The amount of time that the screen saver waits before coming on is variable, however, and you can specify the period of inactivity before it triggers. Our tutorial below will show you where to find and change this setting.
