Re-Enable the Invert Display Keyboard Shortcut in OS X Mavericks & Mountain Lion
Many Mac users noticed that the old Invert Display keyboard shortcut disappeared from OS X Mavericks, Mountain Lion (and beyond), only to be replaced with a different Command+Option+F5 keyboard shortcut that summons Accessibility Options, from which you now have to manually invert the screen by checking a box on or off. If you want to get the good old fashioned Control+Command+Option+8 inversion keystroke back on the Mac, here is how to enable it again:
- Open System Preferences from the Apple menu and choose “Keyboard”
- Choose the “Keyboard Shortcuts” tab, then choose “Accessibility” from the left menu
- Locate and check the box next to “Invert Colors”
- Close out of System Preferences
Hit Control+Option+Command+8 to invert the display colors, and hit those keys again to normalize the display again. Just like the good old days of Mac OS X.
Display color inversion has had a long history of being used as a prank on unsuspecting users, which can be hilarious, but it actually has legitimate uses as well. For those with visual challenges and some forms of color blindness, it can make certain screen elements easier to see, and even for those with normal eyesight it can be a great feature to enable in dim lighting to reduce eye strain and make it more pleasant to read and use a screen at night (though it’s a very different experience than from apps like Flux).
In case you were wondering, the screen colors can also be inverted with the iPad or iPhone too.
