How To Move Mac Dock To Side Of Screen - Regaining Vertical Screen Realestate

Vertical screen space can be much more important on a computer than horizontal space. Mac's come installed with the Dock on the bottom of the screen and this does take up a lot of space - specially on small MacBook's. A better place for the Dock is on either the left or right side of the screen. 

You can change the position of the Dock in System Preferences.

1. Open System Preferences. 

2. Click Dock. 

3. On 'Position on Screen' option, choose either; Left, Bottom, or Right.  

There are also other options for the Mac Dock that you can enable in System Preferences, like auto-hide and show - the option that hides your dock, then makes it re-appear when you move your mouse to the edge, where you have positioned the Dock. 

You can also resize the dock to make it smaller to larger. This can be done in System Preferences > Dock or by dragging the divider (line before Downloads folder).
