Mini Display port Displayport DP to VGA for Mac Only?

[InfoTiger]

Why lots of place state: Mini Display port Displayport DP to VGA Converter Cable for Mac?

Need a Mini Display port to VGA for my 6970 eyefinity.
Is it active the same as a regular Display port to VGA cable?

I can't fathom any reason why it would be Mac-only; I'd have to guess that they're specifically angling for Mac users. It should work just fine with a 6970.
