Update macOS

Close unnecessary apps and browser tabs

Sometimes, the slow internet connection may be caused by apps and opening browser tabs running in the background. They will occupy a lot of CPU to make your internet connection slow. Continuously refreshing and downloading data is the key to slowing down the internet connection.
