BREAKING NEWS: What is ostensibly the last update to 10.4 before the release of Leopard (10.5) in a few months is now available via Software Update.

OS X 10.4.10 doesn’t seem to be a major update and is a moderately sized one (22.1 MB for me, 49 MB for some, 79.1 MB for others – depends on your setup and current state of OS). SU tells us this:

The 10.4.10 Update is recommended for PowerPC and Intel-based Mac computers currently running Mac OS X Tiger. This update includes general operating system fixes, as well as specific fixes or compatibility updates for the following applications and technologies:

- RAW camera support
- Mounting and unmounting external USB devices
- Support for 3rd party software applications
- Security updates

As usual, be wary. If you can wait for word from the foolhardy among us (like me) for initial impressions first, do so. Mine had a kernic panic on the first reboot – which required a hard restart, then it rebooted twice after that before it came through. Aside from that though, so far so good. And don’t forget that it’s always a good move to run DPR before and after installing any update.
