Has anyone installed this without any problems, I only ask this when there are firmware updates. Here's what the update states, This SMC Firmware update adjusts the fan behavior in MacBook Pro systems (15-inch and 17-inch) when running under high workload conditions. 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. I have the early 2008 macbook pro model with the specs listed in my public profile, not sure if this shows up on the newer macbook pros!
