Somewhat surprisingly, Apple released version 10.6.6 of its Mac OS X operating system today. The new version, which ranges from 160 megabytes to 1.06 gigabytes should you download the combo updater, adds the following fixes and changes according to Macworld:
– App Store integration and support.
– Fix for a cropping problem with some PostScript printing in landscape mode.
– Fix for an issue with ATI graphics card-powered Macs where connecting an external DVI display could yield erratic mouse pointer movement.
– Fix for a single security vulnerability related to the PackageKit system, preventing a man-in-the-middle attack that could force the app to quit or potentially execute arbitrary code.
The update requires Mac OS X 10.6 or later to install and run and can, as usual, be snagged via Mac OS X’s Software Update feature.
