Apple released an update on Friday for their MacBook Air addressing an issue concerning one of the dual processors shutting down during video playback. Not everyone seems to experience this issue, however a number of users on MacRumors forum had been complaining about this shutdown which apparently is heat related. In order to work around the issue they’d been using a program called CoolBook which kept the Air running even when video playback maxed out the processing power (driving up internal heat and causing a processor to shut down). Users who have installed this update report that it cures the processor shutdown but requires that CoolBooks usage be discontinued and according to several forum messages the fix seems to work in part by backing down both processors’ speed to 800 MHZ during periods of intense video use.
