Mac Computer running slow after software update
Is it possible anybody could help me understand why my computer is running slow. Just yesterday I updated my MacBook Air (13-inch, Early 2014) software to macOS Catalina and since then, my computer gets overheated within 5 minutes of use, runs slow when I'm typing or clicking on an app, or when I want to watch Netflix the screen messes up by running slower than the actual show. I'm not sure if its because I have an older computer or what, but I'd like to know if I should just switch back to the original software and remove the macOS Catalina.
MacBook Air 13", macOS 10.15
