For those of you who own one of Apple's new MacBook Air or MacBook Pro systems that were released in June, Apple has made a software update available. The update is around 127MB in size and includes bug fixes and performance enhancements for the systems' graphics, and their ability to communicate with some USB devices.
While Apple didn't reveal the specific problems addressed by this update, recently a few owners of the new MacBooks have reported noticing flashing displays when waking the system, washed-out or high-contrast colors when using external displays, and odd graphical artifacts when using some programs and system features like Launchpad.
If you are experiencing these or other problems on your MacBook system, then try seeing if this latest update helps. The update should be available through Apple's Software Update service in the Apple Menu (this will launch the Mac App Store to get the updates), or can be downloaded as a standalone installer from Apple's Support Downloads page.
As always, be sure to fully back up your system before applying this or any other update.
