    Default Apple Releases SMC Update for its Notebook Computers


    Apple has issued owners of MacBook Pros, MacBook Airs, and basic MacBooks with an SMC update Wednesday evening to address a potentially critical failure of Apple's notebooks reaching 1000 battery charge cycles.

    According to the update information, the problem is pretty rare and would cause the notebook computers to “unexpectedly shut down or stop functioning” after reaching 1000 battery charge cycles. Even if you've never experienced the problem, it's recommended that you install the update to prevent the problem from ever affecting you in the future.

    To install the update, you will need to have at least 25% of your battery left, or be connected to a power source:



    The update also warns that when it’s installing the update your computer screen will turn gray and the fans will spin at a very high speed. You shouldn't disturb the computer during this process. Afterwards, your computer will reboot and allow you to log in and continue where you left off. You should save anything you were working on prior to updating.

    You can go to the  menu and click on “Software Update” to bring up the update, or you can download them manually from Apple's Web site.

    Sounds like a bios/uefi update to me. Make sure you aren't doing anything else while this is updating and that there are no other programs running. Trust me you don't wanna mess it up, it happened to my last computer and I had to get a new one altogether.

    Take the battery out and put your tongue on it. It'll give you that 1% you'll need.

    1000 battery cycle? My MBP is over 6 years old and I'm only at 606 cycles. Is it really that common for people to hit 1000 cycles?

    Would a potato work in place of the battery? I'm really worried

    There are apps you can download that tell you.

    Must be for either Mountain Lion or the latest Macs cos my late 2011 MBP 15" running Lion (hated Mountain Lion) doesn't have an update available.
