How to Move a Window

Window moving on a Mac is very much like moving a window in Windows. Look at the top of the window for your Title bar, left click in the middle of it, and while holding down the left mouse button (yes, there is a right and left mouse button on your Mac Mouse), drag the window anywhere you want on your screen.

The key is placing your mouse pointer in any empty area on that Title Bar before you press and hold the left mouse button down and move it.
