If you picked up one of the new MacBook Air notebooks that Apple released recently, you'll wanna fire up Software Update to pull down the EFI Firmware Update 2.0. It fixes an issue where the Air boots or wakes to a black screen or becomes unresponsive. We're sure it's rare, but we think we speak for everyone when we say that we'd rather something like that not happen at all, so take care of that update, okay?
