Red, yellow and green lights on iTunes

Question

I notice on some of my friends laptop, the itunes player has three lights where the file edit, veiw, controls and all the other stuff suppose to be. Is that just for Mac system or is it for all laptops?

Answer 1

If you talking about those colorful circle buttons on top-left of the image below, then those are your close, minimize, and maximize buttons. (left-to-right)

Answer 2

Someone should mention that on the Mac, the menu bar is always at the top of the screen, not the top of each window. So you just needed to look a little higher to find the menus you needed.

Answer 3

Here's a post that explains those. To quote:

In the upper left hand corner of every window on your Apple computer, you’ll see three buttons: red, yellow, and green.

The red button closes the window but not the application. To close the application, depress the Command key next to your space bar (⌘) with your left thumb and tap the letter Q with your ring finger.

The yellow button minimizes the window. If you click this button, you’ll see the window swoop into your dock. If you want to see the window again, simply click the small icon representing that window and it will swoop back to center stage.

The green button toggles your window between two optimal sizes. One setting usually fills your display height and/or width. You choose the other setting by dragging the bottom right corner of your window up, down, left, or right, until it’s just right. The next time you open that application, your windows will “remember” your settings.
