Make your Mac OS X display black and white (grayscale)

I was just reminded of an old trick to make your MacOS display black and white, or grayscale. To do this, just follow these steps:

  1. Click the apple icon on the menu bar, then select System Preferences
  2. Click Universal Access
  3. When that dialog is displayed, click the Seeing tab (if it's not already selected)
  4. In the Display area, click the Use Grayscale checkbox

This should make your entire Mac display (monitor) black and white. I don't do this too often, but it can be a nice way to read documents.

Here’s what the Universal Access dialog looks like on a Mac OS X 10.6 system:

As you can see in that Display area, you can also change the display using a magic keystroke, but since I can never remember that keystroke, I just make the display black and white using this approach.

If you ever want to make your Mac display black and white, I hope this has been helpful.
