Are you having trouble with your Mac constantly switching screens? Don’t worry, you’re not alone! This issue is actually quie common and can be caused by a variety of things. In this guide, we’ll walk you through figuring out the cause of your screen-switching woes and how to stop it from happening.
First, let’s figure out why your Mac is switching screens. The most common cuses are if you have multiple monitors connected to the same computer, or if you have Automatic Brightness enabled in System Preferences. If either of these is the case, then read on for solutions.
If multiple monitors are connected to your Mac, then it could be that your Mac is tryng to move windows between screens when it thinks that would be more convenient for you. To fix this, open System Preferences > Displays and uncheck “Automatically rearrange spaces based on most recent use”.
If Automatic Brightness is enabled in System Preferences > Displays, then it culd be that your Mac is automatically adjusting the brightness of the screen when it detects changes in ambient light level. To fix this, uncheck “Automatically adjust brightness” in System Preferences > Displays.
Lastly, if neither of these solutions works for you then try resetting your NVRAM (Non-Volatile Random Access Memory). To do this shut down your Mac and turn it back on while pressing and holding Option + Command + P + R for 20 seconds. This should reset any settings that may have been causing the issue with your screen switching.
We hope this guide has helped you figure out why your Mac was switching screens and how to stop it from happening! If none of these solutions work for you then consider contacting Apple Support or an Apple Certified Technician for further assistance.
Preventing Screen Switching on Mac Big Sur
To stop your Mac from switching screens in Big Sur, you’ll need to open System Preferences and go to the Mission Control settings. Once there, make sure that the box labeled “Automatically rearrange Spaces based on most recent use” is unchecked. This should stop your Mac from automatically switching between desktops or spaces when you switch applications.
Stopping Multiple Screens on Mac
To stop multiple screens on a Mac, you can either exit Split View or switch to full-screen view. To exit Split View, move the pointer to the top of the screen to reveal the window buttons and then click the full-screen button in either window. That window will exit Split View and the other window will switch to full-screen view. Alternatively, you can also switch both windows to full-screen view by clicking the green full-screen button in each window.
