Hardware

Display resolution

2880x1800 on my 15-Inch Retina Display MacBook Pro.

Unfortunately Virtualbox (5.1.14) can only give 1440x900 (tested on Ubuntu & Windows). See a workout http://tusharm.com/articles/win7-on-retina-display-with-virtual-box/.

Touchpad

Need to press a little bit (instead of touch) for the left-click effect.

The right click is called secondary click in OS X. By default it is click with two fingers. We can change the setting by going to System Preferences/Touchpad/Secondary click.

Scroll: two fingers move up/down. The direction is like moving a paper; i.e. scrolling up will gradually show the next part of the content.

Zoom in/out: pinch with two fingers.

Smart zoom: double-tap with two fingers.

CPU information

sysctl -n machdep.cpu.brand_string

My macbook Pro 2015 shows i7-4980HQ CPU @ 2.80GHz.

Tips

• Got a New Mac? Do This First!
• Upgrading to macOS Sierra (nee OSX) for R users

Launch an application

• F4 key - LaunchPad
• Command + Space - Spotlight search

Close an application

Clicking the red button does close/quit an application/a program. You need to use Command-Q.

Another answer: The red close button just closes the window. It is up to the application whether it quits or not - typically if the application uses documents or it has other windows that can be opened it will not quit. Applications with a single window (System Preferences, for example), will usually quit when the window is closed, since there isn't anything else it does.
