Rogue Amoeba’s Fission audio editing software gets a minor update with version 2.1.1, which offers a lone feature addition: the Batch Converter now accepts folders containing audio files as well as individual files. The release also ensures that the Save panel remembers the last saved location, corrects an issue with chapterized AACs and very large image files, and fixes an issue with the Mac App Store version where attempting to save a file would cause an error. Additionally, Fission now includes a hidden preference accessed via the Debugging window that enables the app to check for and prevent rare instances of Normalization clipping.

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.
