Solves problem with external displays
Apple has released Mac OS X 10.6.6, an upgrade available through Snow Leopard's Software Update feature. The focus of the patch is almost entirely on adding the Mac App Store client, which lets users quickly buy, install and update Mac software while giving Apple a cut of the revenue. There are in fact few other recorded changes in v10.6.6, limited to one security and two bug fixes.
Newly solved, for instance, is a problem with Macs using ATI graphics cards, which could potentially experience "erratic" mouse cursors when an external monitor is connected via DVI. The update also copes with a cropping problem when performing postscript printing in landscape mode. The lone security fix addresses a man-in-the-middle exploit possible with PackageKit.
Four different versions of v10.6.6 are available. The primary update is 143.59MB, and meant for v10.6.5 owners only. Alternately people can download the cumulative Combo update, measuring 1.06GB. Snow Leopard Server owners can download their own regular and Combo updates, sized at 143.5MB and 1.15GB respectively.
