With version 8.0.3, Digidesign has brought Snow Leopard compatibility to its professional audio editing software Pro Tools, which also now requires an Intel-based Mac. In general, Pro Tools 8 offers a refreshed interface, the capability to work with three times as many audio tracks, an added Score Editor, a new MIDI editor, an Elastic Pitch feature, and new track compositing capabilities. (New purchase and upgrade prices vary widely.)
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.
