Two weeks ago, Apple took an official stance on the increasing number of complaints that certain MacBook Pro models were plagued by stalling and clicking hard drives. The company put users’ minds at ease by reassuring everyone that it wasn't a mechanical defect, and promising a firmware fix
down the road. That fix has now been crafted and posted
by Apple, and is available for download to anyone who is affected by the issue.
It specifically affects MacBook Pros with 7200 RPM hard drives introduced in June 2009 or later, so if you happen to have purchased one of those in the past two months this may be your saving grace.
Apple also released the Bluetooth Firmware Update 2.0.1
today. According to the release notes, this update provides bug fixes and better compatibility with the Apple Wireless Mighty Mouse and Apple Wireless Keyboard on all Mac systems with Broadcom Bluetooth chipsets.
