Apple has issued updates for MacBook, MacBook Pro, and MacBook Air notebook models to fix a rare battery issue. The updates are available via Apple’s software updates page or through Software Update and the Mac App Store.

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.

Update: MacRumors forum member Dempson looked inside the updates and found they are for the following machines:

MacBook7,1 (13-inch, Mid 2010)

It’s only certain models apparently, but it doesn’t state which. See here ( for MBP (here ( for everybody else).

If you don’t get it in Software Update, you most likely don’t need it. If you’re skeptical, download it manually and see if your system takes it (it will tell you it’s not meant for your system if it isn’t).

Seems it isn’t for 2011 MB’s.
