Placing the dock on the left-hand side of the screen maximizes your available vertical screen space, useful if you have a MacBook with a smaller screen. Head to System Preferences (System Settings) > Dock & Menu Bar to change things like the placement of your dock. Make sure your user account is selected on the left, then click on your current user icon to change. You can change what is displayed under the System Preferences (System Settings) > Users menu. Your user icon is what you see when you first boot your Mac, so make it personal. You’ll also find a few other options here, like the macOS accent color (which is used to highlight objects like menu items or desktop icons). If you go for Automatic, your Mac will change based on the time of day. You’ll find this option under System Preferences (System Settings) > General where you can choose from light, dark, and automatic themes.

MacOS now has a dark theme available, which is much easier on the eyes when using your computer at night. Choose Between Light, Dark, and Auto Themes You can also set any image in Safari as your desktop wallpaper by right-clicking (or two-finger clicking) on it and selecting “Use as Desktop Wallpaper” from the context menu. We recommend saving energy instead and changing the “Turn off display after” setting to something nice and short under System Preferences (System Settings) > Battery (or Energy Saver on a desktop Mac.)

If you still use a screen saver you can change this here too.
