Apple releases MacBook Pro firmware in update to address battery issues

In the second MacBook Pro firmware update in as many weeks, Apple on Tuesday released version 1.7 of its MacBook Pro SMC Firmware to patch a problem regarding the laptops' built-in battery.

MacBook Pro Update

Tuesday's update, which specifically targets early-2011 and mid-2010 MacBook Pros in both 15-inch and 17-inch configurations, fixes an issue that caused the laptops to unexpectedly shutdown after the non-removable battery had undergone over 1000 charge cycles.

The problem was most recently addressed at the end of January with SMC Firmware Update 1.6, which was released alongside identical updates for all MacBook and MacBook Air models produced after 2009.
