The days when Windows users should have updated their computers with the latest security addons are not over but the days when Leopard users should do that, are here. Apple has just released an update to its Mac OS that brings the OS to version 10.5.3.

This update is recommended for users of Mac OS X 10.5, 10.5.1, and 10.5.2 Leopard. According to Apple, the update is enhacing the sability, compatibility and security of the Mac. The update is also addressed to some issues with Mail, iChat, iCal, Airport and other features as well. I’m talking about a fix for stuttering video and audio playback in certain USB devices, fix for some attached drives, the stability issues with Word of the Day, iTunes Artwork and Slideshow and RAW support for a couple of digital cameras.
