How to Downgrade to macOS Catalina
So a few months ago I upgraded my Mac to macOS Big Sur and these few months I have noticed that my Mac is running really slow, and the battery is draining really fast everyday, this is a pretty new MacBook so I don't think it have problems with the CPU or anything, so can anybody PLEASE teach me how to downgrade to macOS Catalina, I am a student so I use my Laptop a lot. Thanks! (BTW my Mac is currently running macOS Big Sur 11.0)
