SMC 1.3 update for MBP
Apple has released a v1.3 System Management Controller (SMC) update for 15- and 17-inch MacBook Pro systems. The upgrade adjusts the fan behavior of a Pro when the system is operating under high-workload conditions. Software is installed in the Applications/Utilities folder, and then launched automatically.
The SMC is a micro-controller on the logic board that regulates various functions such as power and heat management. The update is sized at 833KB, and compatible with Mac OS X 10.4.11 or higher. Pro owners can download the file from Apple's support page.
