Apple has finally released the seventh point update to Mac OS X 10.5 Leopard. The update is now appearing in Software Update, with various updaters available from Apple's Support Downloads page. Security updates have also been issued for Mac OS X 10.4 Tiger as well as Safari.

The 10.5.7 update addresses a number of issues, including some printing issues, iCal syncing with CalDAV and MobileMe, Mail syncing with Notes, and Parental Controls.
