How to Invert Colors on a Mac

Open the Apple menu Mac Apple. Click the Apple logo in the top-left corner of the screen. A drop-down menu will appear.

Click System Preferences…. It's in the drop-down menu. The System Preferences window will open.

Click Accessibility. This is in the System Preferences window.

Click the Display tab. You'll find it in the pane on the left side of the window.

Check the "Invert Colors" box. It's at the top of the window. You should see your Mac's display colors invert at this point.

If you are running OS Mountain Lion, you can use the keyboard shortcut. If you want to enable or disable color inversion without opening the Accessibility menu, you can press Control+⌥ Option+⌘ Command+8 to do so. In OS High Sierra, you can enable this keyboard shortcut in System Preferences > Keyboard > Shortcuts.
