MacBook/MacBook Pro EFI Firmware Update 2.0
Apple has released EFI Firmware Update 2.0 for both the MacBook and MacBook Pro. The updates are for the mid-2010 models of the MacBook and the mid-2010 models of the 13-inch MacBook Pro, and address an issue where external monitors connected to your laptop may exhibit an undesired purple coloration. Your laptop must be plugged in to install the firmware update, which will take several minutes, and Apple recommends that you not cut power to the computer during the installation. If you’re not sure if your laptop needs the update, use Software Update, which will present it as an option only if it’s appropriate. (Free, 1.98 MB)
