Yep.. You are not wrong! Even there is a menu for almost every item if you right click; there is no right click on your MacBook’s Touchpad. Mac uses single button mouse technology and if you buy an Apple mouse, there is no right click (or i don’t if there is one).
Solution: CTRL+Mouse Click. It will act as right click and open you the necessary menu.
Better solution: Buy a universal USB or Bluetooth mouse (a mouse for a PC). It will work on your MacBook and you will have your right click.
