Apple on Monday released Mac OS X 10.5.4 fixing several issues with iCal, AirPort, Safari, and Spaces & Expose.
AirPort has been updated addressing reliability issues with 5GHz networks and issues that may result in slower performance in Logic Studio or MainStage.
iCal received updates fixing seven issues with the application including reliability for meeting requests, cancellation notices, delegation, and syncing with iPhone. The update also fixed an issue that prevents deleting an iCal event without notifying the creator.
iCal now includes a checkbox that excludes information-only calendars from affecting availability and a problem with copying and pasting attendees from one event to another has been resolved.
Performance issues when loading secure web pages in Safari has been resolved. Another performance issue where client certificates are on a smart card has also been addressed.
Spaces & Expose received a couple of updates, as well. An Expose problem that may result in only a subset of windows being shown has been fixed. An issue has been fixed when switching from a space keeps the Finder as the active application and dragging an application from the list of application assignments does not assign the app to the Space have both been addressed.
Improvements for L2TP VPN client reliability have also been made.
The update is available from the Mac OS X Software Update mechanism or directly from Apple's Web site.
