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. About MacBook Pro SMC Firmware Update 1.3

The updater application will be installed in the /Applications/Utilities folder and will launch automatically. Please follow the instructions in the updater application to complete the update process.
The company also links to a Support article
titled “About the SMC Firmware Updates,” for more information on the update. The piece contains instructions for installing the firmware properly, a topic we'll be covering later on today.
