If you don’t have a 2 button mouse connected to your Mac laptop there are only 2 other ways to perform a right click:
1. Hold down the Control key while you click
2. Click and hold down your click for a second or two
BUT today I discovered a much nicer version for when I’m on the road and not hooked up to a real mouse. You can tap the trackpad with two fingers for right-click. To enable it on your Mac go to System Preferences, click “Keyboard & Mouse”, and select “Tap trackpad using two fingers for secondary click”. Voila!
