Schmitz Duplicating a fix provided by the recently released [1]Firmware Update 1.6, Apple has released [2]MacBook Pro SMC Firmware Update 1.7 to target a range of specific models ' both 15- and 17-inch MacBook Pro models released in mid-2010 and early 2011. (Firmware Update 1.6 was not targeted to any specific models.) Like the previous update, this one addresses a 'rare issue' that caused laptops with a battery that had accumulated more than 1,000 charge cycles to shut down and possibly fail to boot back up again. As always with firmware updates, we recommend relying on Software Update or the App Store app to ensure you get the firmware update for your MacBook Pro, and be careful not to interrupt the update process.
