After patching a similar issue on old-generation MacBook computers, Apple this week has released a new firmware update addressing problems with the power management system in MacBook Pros.
Apple’s new MacBook Pro SMC Firmware Update 1.7 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,” Apple states.
System Requirements include OS X 10.6.8 (Snow Leopard), OS X 10.7.5 (Lion), and OS X 10.8.2 (Mountain Lion). The update applies to MacBook Pro (15 and 17-inch, Early 2011) and MacBook Pro (15 and 17-inch, Mid 2010) models.
Supported Languages include Deutsch, English, Français, Español, Italiano, Nederlands, Dansk, Norsk Bokmål, Polski, Português, Português (Brazil), Pусский, Suomi, Svensk, Chinese, Japanese, and Korean.
