Mac OS X 10.5.6 released

Apple just released Mac OS X Leopard 10.5.6. Here are the most relevant changes for video professionals (not many as we're frequently overlooked unfortunately):

Graphics

* Includes general improvements to gaming performance (I think they are referring to improved OpenGL performance in general, which affects applications like Motion and hopefully will boost poor GeForce 8800GT performance).
* Includes fixes for possible graphics distortion issues with certain ATI graphics cards.

Networking

* Improves Apple File Service performance, especially when using a home directory hosted on an AFP server. Important: If you are using Mac OS X 10.5.6 (client) to connect to a Mac OS X Server 10.4-based server, it is strongly recommended that you update the server to Mac OS X Server version 10.4.11.
* Improves the performance and reliability of TCP connections.

General

* Includes Mac OS X security improvements (always good).
* Adds a Trackpad System Preference pane for portable Macs.

See the full list here.

The changelog (which I don't have access to but was leaked on the net) for one of the beta versions of this patch listed a fix for various hiding bugs. I know several people have had a problem with Final Cut Pro where they have been unable to show it again after hiding, so it would be interesting to see if this fixes the issue.

Once again, don't install this update until it's been out for at least a week (minimum) and you've checked around internet forums to see if people have experienced any issues. When you do update, always assume the worst WILL happen and clone or backup your hard disk first. Never update in the middle of a project and don't update early if none of the issues fixed affect you.

However, it is good to install security updates as soon as possible (again, wait to see if people report problems, although this is normally rare with security updates). Luckily Apple have included the security content of this update as a separate download for those who don't want to risk upgrading their OS. It is available in Intel and PowerPC versions.

P.S. It's good to know that Apple aren't rushing to patch the XDCAM bug with Color 1.0.3 as, clearly, improving the performance and reliability of Chess is far more important ;)

Update 12/16/08: Lots of people reporting problems with this update.
