Persistent appearance of the display brightness overlay image


The other day after I had awakened my Mac from sleep, I noticed the sudden and persistent appearance of the display brightness feedback overlay image. The white-colored image normally disappears within a few seconds after pressing one of the trigger keys (F14 and F15 on an Apple Pro Keyboard). Intrigued, I documented this phenomenon by capturing the screen display twice in succession using the keyboard shortcut, Command-Shift-3. I browsed the Console log to search for clues but found none. Finally, I rebooted the computer, and the screen went back to its normal appearance.

  1. wait a sec here…xp on a mac? when did this happen?!

  2. Mac users have been able to run the Windows OS for over a decade using software programs such as SoftWindows and Virtual PC. The downside to using these old emulators was that they were slow and restrictive to what they would support. By switching to the Intel microprocessor, Apple has made it possible for developers to come up with advanced programs like Parallels, VMware, and BootCamp that enable Windows XP and Vista to be run on a Mac at near-native speeds.
