In addition to the AirPort Base Station and Time Capsule firmware updates, Apple on Friday also released MacBook Pro SMC Firmware Update 1.5, which reportedly “resolves an issue where a MacBook Pro being used with a power adapter may unexpectedly shut down under heavy workload if the battery charge level is near empty.”
Per The Unofficial Apple Weblog, it’s not entirely clear which models of MacBook Pro are covered by this firmware update.
The update can be located, snagged and installed via Mac OS X’s built-in Software Update feature and requires a MacBook Pro running Mac OS X 10.6.8 or later on the Mac OS X 10.6 end and Mac OS X 10.7.2 or later for the Mac OS X 10.7 end to install and run.
This one’s still sort of up in the air, so if you’ve tried the firmware update and noticed any major changes, please let us know in the comments.
