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.
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
