Apple has updated Mac OS X for both Intel- and PowerPC-based Macs, bumping its operating system up to version 10.4.5. The patch incorporates a number of fixes and improvements for the OS itself, along with a number of compatibility tweaks for third-party and Apple-branded applications. It also includes Apple's most recent security updates.

More information about the update's particular changes can be found here (http://docs.info.apple.com/article.html?artnum=303179). There's a version of the installer for systems already running Mac OS X 10.4.4, which weighs in at 16MB for the PowerPC release and 98MB for the Intel version - get them here (http://www.apple.com/support/downloads/macosxupdate1045.html) and here (http://www.apple.com/support/downloads/macosxupdate1045forintel.html), respectively.

Apple also posted a complete installer designed update any version of 10.4 to the latest release, which you can find here (http://www.apple.com/support/downloads/macosxupdate1045combo.html). And you can download the Mac OS X Server 10.4.5 update here (http://www.apple.com/support/downloads/macosxserver1045.html). ®
