With iPhoto 9.4.3, Apple has enhanced the consumer-level photo management app’s Photo Stream support and fixed a handful of bugs. Photos can now be deleted from My Photo Stream by dragging them to the Trash, you can use File > Export to export photos from Photo Stream, and raw images manually imported from My Photo Stream are now editable. On the bug-squashing side of the equation, one fix prevents manually rotated photos from appearing unrotated when shared to Photo Stream, another addresses a crash when syncing to Facebook, a third prevents calendar text from appearing at the wrong size and resulting in order cancellation, and the final one fixes a problem that could cause books to have an incorrect number of pages after rearranging two-page spreads.

Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
