Apple has released the latest version of Leopard, with bug fixes and security updates accompanying the fifth update to the operating system. The company sent over a list of improvements about 30 minutes ago, and the full list of fixes and improvements should be up on Apple’s Web site any moment with the update itself popping up in Software Update. iPhone 3G Accessories says two notable updates from the “General” section were a fix for the video playback problems that affected some MacBook Air owners, as well as a puzzling bug “in which some Macs could unexpectedly power on at the same time each day,” which would be the first time I’ve heard that one.
