Apple released its latest update for OS X, 10.6.7. The relatively minor software update for Snow Leopard brings bug fixes and general maintenance updates for a number of system components, and addresses issues with the Mac App Store, which shipped with OS X 10.6.6 in January.
In addition to zapping Mac App Store bugs, the update also improves the reliability of Back to My Mac, the service which allows MobileMe users to access their computers remotely (including file and screen sharing) from anywhere they have an active internet connection, so long as their Macs are powered on and also connected to the internet.
