Apple Releases MacBook Firmware Update To Address Rare Battery Issue

new macbook pro 2012

Apple has released a new SMC firmware update for the MacBook, MacBook Pro, and MacBook Air. “This update addresses a rare issue on some Apple notebooks where a battery that has accumulated more than 1000 charge cycles may unexpectedly shut down or stop functioning,” according to Apple. This applies specifically to older batteries, but the update is recommended for all MacBook models.

You can find this new firmware update in the Mac App Store or download it directly from Apple’s website.

    I have the exactly same issue with my MacBook late 2009 with 700 cycles (I have to run my MacBook always on charger….) but that model isn’t covered by this update. Why Apple? Why?
