While small in terms of numeric progression, Audio Hijack Pro 2.10.1 from Rogue Amoeba adds some welcome new features. The latest release of this audio recording program includes the latest version of the Instant On component (5.0), which can now capture audio from sandboxed applications purchased from the Mac App Store. The Multi-Process mode, previously used in conjunction when pulling audio from several Web browsers, is now used for additional applications to improve audio capture. Finally, audio pulled from input devices can now be configured in Audio MIDI Setup instead of always using channels 1 and 2. ($32 new, free update, 5.2 MB, release notes)
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
