Last night I installed the freshly released update for Tiger (update 10.4.10).
The installation went fine, but took unusually long time, which made me a little worried for a moment (a spinning wheel is not the best indicator of progress).
After the problems I (and many others) had with 10.4.9, I recommend doing at least these steps in order to install a MacOSX Update:
- close all the apps
- backup important stuff
- launch Disk Utility and verify the disk *and* disk permissions
- start the installation
- don't touch your machine until the update is done
- start praying
