Macs are very tweakable machines. macOS is a great operating system because most settings work just fine as they are, but with a few simple Terminal commands you can change just about anything that doesn’t suit you perfectly.
These commands are called Defaults Write Commands, and when entered into the macOS command line, called Terminal, they can totally change your experience and make a lot of aspects of the OS better.
