Premiere Pro and Soundbooth both appear to function on Leopard, but Adobe has nonetheless squashed some bugs in updates for each program. Links to each over at The Unofficial Apple Weblog.
Keep those compatibility reports coming. We’ve heard some general frustrations with Leopard (as can happen with any OS update), and ongoing specific issues with M-Audio products. Digidesign Pro Tools 7.4 remains unsupported on the new OS. (Note that “unsupported” doesn’t necessarily mean it won’t work, as one reader observes.) I’m running Leopard here successfully on a MacBook Pro. It’s working nicely, and there are some nifty usability improvements, but on the other hand I’m not sure I’d go out of my way to make the leap when Tiger works so well.
