Responding to complaints about CPU power use under load that eerily echoes a 2011 issue and also resolving a tricky issue regarding some USB 3.0 drive enclosures, Apple today issued a software update for just the latest models of MacBook Pro and MacBook Air. The "Pro Update 1.0" release notes do not specify the power consumption and USB problems in any detail, but reports of the machines losing battery while under high load even while plugged in have been spotted in support forums.
