Apple has updated Mac OS X Leopard, bringing the current version of the operating system to 10.5.5. The 136MB download addresses 33 issues with the operating system.

This update fixes problems with several of the applications found in Mac OS X, but the one that users may be interested in the most is MobileMe. Updates to the online service in 10.5.5 fixes overall sync reliability and Back to My Mac reliability, according to Apple.

There are several updates to Apple’s built-in e-mail application. Performance issues related to displaying IMAP messages have been fixed; SMTP settings for AIM, Compuserve, Hanmail, Yahoo!, and Time Warner Road Runner, have been addressed; and an issue in which RSS feeds could temporarily disappear from the sidebar has been fixed.

Apple’s calendaring application, iCal, will more accurately handle repeating events and be faster when choosing meeting attendees with the update. Syncing published calendars now works correctly and events can now be moved to a different calendar by invitees.

The Disk Utility and Directory Utility have been updated improving reliability when rebuilding a software mirror RAID volume in Disk Utility. The reliability of server status displayed in Directory Utility has also been improved.

Users of Apple’s built-in backup application, Time Machine, will be happy to hear that the reliability of the app has been improved when using Time Capsule; the update fixes an issue in which an incorrect alert message could appear stating that a backup volume does not have enough free space; and performance issues that may affect initial and in-progress backups has been fixed.
