The 10.4.6 update for Mac OS X has been released. This is a big update (~140 MB for PPC and ~192 MB for Intel) and fixes many problems. A smaller (~65 MB for PPC or ~163 MB for Intel) 10.4.5 to 10.4.6 update file is also available on the Downloads page. Just run Software Update on your Mac and tell it to install or you can download the update file manually if you have a computer that is not connected to the Internet.
