I didn't feel this thread was about complaining, but rather people sharing their experiences with it.
Seriously, why would anyone think it should work with an OS that's still in development (and not available to the general public)? Especially when Pro Tools doesn't always update OS support all that quickly?
That being said, it DOES work.
Still, I see nothing wrong with those of us who have Pro Tools, and have Mavericks sharing our experiences with it.
