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.)
Enabling Auto Spelling Correction in Snow Leopard
In Snow Leopard, the automatic spelling correction in applications is not usually activated by default. To turn it on, make sure the cursor's insertion point is somewhere where text can be entered, and either choose Edit > Spelling and Grammar > Correct Spelling Automatically or, if the Edit menu's submenu doesn't have what you need, Control-click where you're typing and choose Spelling and Grammar > Correct Spelling Automatically from the contextual menu that appears. The latter approach is particularly likely to be necessary in Safari and other WebKit-based applications, like Mailplane.
