Want to have a little fun by dressing up your mac in orange and black for Halloween (and giving your co-workers and boss a good scare in the process)? Here’s how:
1. Click on System Preferences in your dashboard (the silver rectangle icon with the apple logo on the right and a light switch on the left).
2. Click on Universal Access, shown near the bottom right corner, in the “System” catagory.
3. Now click the radio button for White on Black under the “Display” catagory.
This will automatically “invert” the colors on your screen. For example, anything that was once white, will now be black. If you want to change your desktop color to invert to orange, like the picture above, you have to start with a blue background (because blue inverts to orange).
To do this go to “System Preferences” and choose “Desktop & Screen Saver” near the top under the Personal catagory. Then choose any blue background under “Apple Images.” Repeat the steps above to “invert” and then show off your spooky computer.
To change back, simply click again on the “Black on White” radio button under Universal Access.
