Apple has released a new firmware update for MacBook Pro (15-inch and 17-inch) users, in an attempt to fix heating issues by adjusting the systems' fan behavior. Apparently, users have been experiencing problems when doing intensive tasks. The update is free to download and install for systems running Mac OS versions X 10.4.11 through 10.5.7 (the latest version of Leopard available).
System Management Controller (SMC) firmware updates for Intel-based computers update the micro-controller on the logic board that controls the power functions for the respective system. Functions controlled by the SMC include power and thermal management, the Sleep LED, and battery, as well as the fans, the Sudden Motion Sensor, ALS, and the power switch.
As usual, Apple's
description of the new firmware follows below.
