During the last evening the Apple company has launched through the Software Update system, an update for all iMacs that have Mac OS X Lion installed. The update is meant to solve some problems of the graphics cards that generated crashes of the operating system when using video editing programs or running complex games. The update released by Apple is only 500 KB and can be applied directly over your operating system by opening the Software Update from the Preferences application of OS X.
