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.)
Spacebar Magnifies Photos in iPhoto '08
In iPhoto '08, you can choose whether double-clicking on a photo will edit it or magnify it. I prefer my double-clicks to edit photos, but every now and then it's nice to magnify a photo. To do that, even when double-click is set to edit, just select the photo and press the Spacebar.
