doesn't work in any released version of OSX
I have one sitting next to me and I try with each new OS update
When it does work I will post at Netkas.org first and then here.
(after which I will be pilloried for not answering every question about every possible thing that anyone would want to know)
Short answer "NO"

The Radeon HD 7970 works great on my Mac Pro -- under Windows 7 -- psych! For hard core gamers, its a cool "weekend" upgrade. I wish AMD would release a "Mac & PC" edition.
