Mac OS X 10.5.4 update
Apple on Monday released Mac OS X 10.5.4, another update to its "Leopard" operating system. In addition to a number of security fixes, the company addressed issues with Adobe CS3, AirPort connectivity, iCal, SSL connections using Safari, and Spaces and Exposé. Specifically, the company said the 59MB update, available via the Software Update, resolves an issue with saving and reopening Adobe Creative Suite 3 ﬁles on a remote server; includes additional RAW image support for several cameras, addresses an issue that may result in a partially installed X11 application, and improves L2TP VPN client reliability. Apple also said the update brings better AirPort reliability issues with 5GHz networks and improves performance in Logic Studio or MainStage over AirPort networks.
In its Safari browser, Apple said that the update fixes potential performance issue when loading secure web pages and also resolves issues that may be encountered when accessing secure web pages with client certificates that reside on a smart card.
The update also brings a plethora of iCal fixes, including better overall iCal reliability for meeting requests, cancellation notices, delegation, and syncing with iPhone. It also fixes an issue in which events in all calendars affect availability by adding a checkbox that now enables information-only calendars to be transparent from free/busy lookups. Apple also said the latest update resolves a UI issue preventing delegated calendars from showing up as a separate window.
Apple also included several security fixes for Leopard, including the previous security-specific updates released beforehand. The update includes many security updates for the Mac OS, Safari, iChat, and several other core applications that can leave a user's computer prone to attacks.
