Apple Updates Mac OS X 10.5 Leopard

Apple introduces a wide range of fixes in Mac OS X 10.5.7, including changes to security, fixes to applications such as iCal and Mail, and improved functioning with Gmail and Yahoo. Apple is updating OS X 10.5 in advance of the rollout of its next operating system, code-named Snow Leopard, which will likely roll out at some point in summer 2009.

Apple has issued an update for Mac OS X 10.5 Leopard that includes general operating system fixes to security, video playback and other areas.

According to Apple, the product versions affected by the Mac OS X 10.5.7 update are Mac OS X 10.5, 10.5.1, 10.5.2, 10.5.3, 10.5.4, 10.5.5 and 10.5.6. The update can be installed via either Software Update or a stand-alone installer.

The update features security fixes, includes additional RAW image support for a variety of third-party cameras, improves performance of video playback and cursor movements for Macs with Nvidia graphics, and boosts the reliability of Gmail and synching contacts with Yahoo, Apple said.

It also performs fixes to iCal and Mail, improves consistency of Parental Controls and application restrictions, and solves a number of printing issues, including an issue that apparently caused third-party printers to print to the incorrect paper tray, according to Apple.

Previous updates to Mac OS X have included security patches for holes found throughout the operating system at different times. Many previous security measures have addressed vulnerabilities created by third-party products working with Macs.

Although its systems have been popularly perceived as safer than PCs, Apple has recommended in the past that users install anti-virus software.

The updates come in advance of Apple's next operating system release, Mac OS X 10.6, dubbed "Snow Leopard." Although the new operating system was a no-show at the Macworld Expo in January, the word is it that the Snow Leopard will make its debut in summer 2009.
