Mac Pro SMC Firmware update released: adjusts fan behavior

Apple has released an SMC Firmware update for Mac Pros.

The update requires Mac OS X 10.4.7, and adjusts fan behavior in the Mac Pro. After this update has completed successfully, your SMC Version will be: 1.7f8. The updater application will be installed in the /Applications/Utilities folder and will launch automatically after restart.

To update the SMC firmware on your Mac Pro, you must quit all open applications, then launch the firmware updater (located in /Applications/Utilities) and click the restart button. The firmware update will start automatically with a status bar. Apple says "During the update your computer fans will run at full speed, but will return to normal once the update completes."

Your Mac will restart again after the update is over.

The new release is available as a 1 MB standalone download.
