My iMac's monitor appears as invers--like a photo negative. Turned off computer. Re-started, and still inverse.
Check Universal Access system preferences --> Seeing --> Display --> black on white and white on black radio buttons.
Control + option + command + 8 button combination.
Go to Sistem Preferences... Universal Access and select Black on White under Seeing.
This took 30 seconds. I am so pleased with this blog!
