How to add applications, programs, files or folders to the Dock on the Mac.
Add items you use the most onto the Dock for maximum work efficiency. A general rule of thumb is all your apps/programs on the left hand side and files/folders on the right hand side.
Locate the item you want to add to the Dock. It can be applications, files, or folders from the Desktop or somewhere in your directory of folders.
Click and drag the icon to the Dock.
Another way to add an application to the Dock is when you’re using the program simply right click (or “Control” and click) the icon on the Dock then scroll to “Options” and “Keep in Dock”.
