The Dock

Trick #2 

  Editing the dock size, magnification, position, and more..

On the upper left hand corner, click the apple logo --> Dock --> Dock Preferences...

From there on, a screen will pop up that should look like this..

From here you can change the following:

Size: changes the size of the icons on the dock

Magnification: causes the icons to enlarge when the cursor is hovered over an icon

Position on screen: changes the position the dock is at on your screen- left, bottom, or right

Minimize windows using: Genie effect- minimizes windows in a slithering manner

                                            Scale effect- minimizes windows in a square like manner

1st check box: causes a window to minimize when it is double clicked on the title bar- in this case, the title bar is the bar with the word "Dock" on it

2nd check box: Minimizes a window into the appropriate application icon. Ex: a safari window will be minimized into the safari application icon, and not off to the side as a separate window

3rd check box: Causes an application in the dock to bounce when clicked on

4th check box: Causes the dock to disappear when the cursor isn't hovered over it, and will reappear when hovered over again

5th check box: Shows little rectangular lights to appear underneath applications in the dock when they are running in the background or open
