Apple releases SMC 1.3 update for MacBook Pros

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.

    MacBook Pro C2D 2.33 says it doesn't need it, so I guess it's okay. I had installed a SMC update some time back and that's about it. My MBP runs cool and I'm using fan control software just in case.

    If anyone who installed this has noticed increased fan use by the laptop after they've installed? (Not talking about immediately upon restart, just general use).

    While I'm not keen on overheating my MBP, I'm def. not psyched about a constant-running fan when running software like CS4, or h***, even Safari, that seem to eat up processor resources quickly.

    Well, one would expect that what you fear is what you would get, as apparently they're trying to keep the computer from getting too hot (probably to save themselves some of that NVidia solder breakage or something).

    @ testudo -
    If that is the case (which I would suspect it is), it is definitely not cool! (no pun intended)
    They need to fix these (nvidia) problems, not mask them. This not only has a noise impact, but a battery one as well. If I had one of these units, I would NOT install this update... and if having issues, demand it be fixed properly... not just kept in check by running the fans faster.

    Note that they don't say which MacBook Pro 15" models require it. I tried it on my Unibody and it says the update isn't required.

    gotta love apple

    They release an update and won't even tell you what versions of their computers it is for. I guess even Apple has realized that calling their computers by model and year is completely confusing and arbitrary.
