Apple just released two firmware updates to address some rare battery issues with the Macbook Pro and Macbook Air lines Tuesday. The firmware can be downloaded directly from Apple’s support website.
The firmware for both models fixes some rare issues with the battery, one of which will shut your Macbook Air down after 1000 charges.
The MacBook Pro SMC Firmware Update 1.8 is available here, and the release notes are as follows:
This update is recommended for MacBook Pro (mid 2012) models.
This update addresses rare issues where the battery unexpectedly stops functioning or the system hangs when the battery charge reaches less than one percent.
The MacBook Air SMC Update v1.8 is also available at this link, and has the following release notes:
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.
So, if your Macbook Pro or Macbook air has these issues, or even if it isn’t currently having them, updating the firmware is probably a good idea. You don’t want your favorite laptop quitting on you at an inopportune moment.
