A couple of Boot Camp updates flew in from Apple's Support desk late Tuesday for owners of 13-inch MacBook Pro models released in mid-2010.
The patches are available for users running either 32- or 64-bit versions of Windows on their Macs, and fix an issue “that causes the Boot Camp Control Panel applet to display an error when the brightness tab is selected and an issue that results in no headphone sound.”
The 32-bit update is 1.5 MB, and requires a 13-inch MacBook Pro running Windows XP, Windows Vista, or Windows 7, while the 64-bit version is 1.03 MB and supports Windows Vista and Windows 7. Both updates require the latest version of Boot Camp, 3.1, be installed.
Users can download the relevant update while running Windows via Software Update or through Apple's Support website. Apple has also kindly set up a step-by-step instruction guide for installation and verification, if you're into that sort of thing.
