How to stop Mission Control from rearranging screens? If I have arranged Finder to the left of the desktop and Slack to the right, and have Sketch further to the right, there's a reason for that. It's an organization strategy to make my work easier and keep track of the many windows I have open. BUT, macOS rearranges them if I click on the application icon from the Dock and rather than swiping over to the screen in the specified order, it moves it next the Desktop.

Is there a way to stop that from happening? A way to pin screens to the desired position?
Go to System Preferences -> Mission Control and uncheck: Automatically rearrange Spaces based on most recent use.
