Mac OS X 10.6.4 is in Software Update

Head on over to Software Update to find the latest OS X dot release.10.6.4 is now available -- and in addition to the usual split between delta and combo updates, and regular/server versions, there's another wrinkle here: the Mac mini released today gets its very own flavor of the 10.6.4 update, presumably because of late changes that couldn't be tracked back into the trunk version of the OS.

The size of the update may vary if you pick it up via Software Update -- we saw 315 MB on a MacBook Pro running 10.6.3. The combo update for all 10.6 systems weighs in at a bandwidth-hogging 887.4 MB.

Here's Apple's write-up on the matter:

The 10.6.4 Update is recommended for all users running Mac OS X Snow Leopard. It includes Safari 5 and general operating system fixes that enhance the stability, compatibility, and security of your Mac, including fixes that:

• resolve an issue that causes the keyboard or trackpad to become unresponsive

• resolve an issue that may prevent some Adobe Creative Suite 3 applications from opening

• address issues copying, renaming, or deleting files on SMB file servers

• improve reliability of VPN connections

• resolve a playback issue in DVD Player when using Good Quality deinterlacing

• resolve an issue editing photos with iPhoto or Aperture in full screen view

• improve compatibility with some braille displays
