Ambrosia Software has released Snapz Pro X 2.1, making the popular still image and video screen capture utility a universal binary for native performance on Intel-based Macs. Other changes provide generally improved performance, support for QuickTime compression sessions, compatibility with the Mac OS X 10.5 Leopard beta from WWDC, the (restored) capability to use "Save Later" when post-processing movie captures, and various bug fixes. The update is free to registered users; it's an 11.8 MB download. New copies of Snapz Pro X cost $30 for still image capture only, or $70 if you want to add movie capture capabilities.

In Snow Leopard, Option-clicking the Volume icon in the menu bar displays a list of sound input and output devices. Choose one to switch to it; it's much easier than using the Sound preference pane. Also, hold Shift and click the icon to set the system volume, which is separate from the general output volume.
