Fun Mac Tricks to Surprise Your Friends

macOS comes with tons of hidden keyboard shortcuts. It’s hard to find out if you have not explored thoroughly. Here are some odd and funny tricks you can do on your friend’s new Mac just for fun.

These keyboard shortcuts allow you to perform these effects in a split second. You’ll be surprised how many Mac users don’t know how they are done.

Full list after the jump.

Zoom In / Out

Okay, this is not the best of all, but it may still trick some. Mac comes with a screen zoom in/out function. The keyboard shortcut here is:

Zoom In

Command + Option + +

Zoom Out

Command + Option +

If it does not work for you, it’s probably because the zoom control is locked. Here’s how you trigger the zoom control lock/unlock:

Toggle Zoom On/Off

Command + Option + 8


Mac contrast trick

I’m not sure if adjusting your screen contrast is really useful, but there’s a shortcut on Mac to turn your screen into contrast mode. Here’s how you do it:

To increase contrast, keep pressing

Control + Option + Command + .

To decrease contrast, keep pressing

Control + Option + Command + ,


Mac invert trick

Inverting turns the screen to opposite colors, so it won’t hurt the eyes when you’re staring at the screen in the dark. However, for those who don’t know Mac is capable of inverting your screen, they might think it’s a problem with their LCD. Invert screen stays even after rebooting the Mac, so unless you know where to change it back, it’s going to stay forever. Here’s how you invert a Mac screen:


Control + Option + Command + 8

Have Fun Trying

The ugliest combination would probably be Invert + Contrast, and it will look something like this:
