I'm a bit late replying here, but does anybody know if Jarte works on the Mac? I used it for a brief period under Windows and it seemed to work very well. There is both a free and a paid version. The website is http://www.jarte.com . I haven't done much editing on the Mac, but I've done a bit with both TextEdit and Pages and they both seem pretty good. Regarding audio editing, I have never done that so can't really recommend anything. I've had a brief look at GarageBand, and it looks pretty cool. In addition it is said to work well with VoiceOver, which is Apple's built-in screen reader and which I've found to be quite good.
