Quote - Check out my system specs in my sig below. I have Vue 7i 7.4 right now because I can live until 8.0 comes out. I can say mine works fine for my Vue 7i but not about 7.5x or C4D, sorry.

Thank you for your input, however, my question relates specifically to xtream and C4d.  

Over the years, I have been using various iterations of Vue for Mac, currently Vue 6 Infinite but at this point, aside from my video editing software (Final Cut, etc.) my most heavily used software is C4d and it is for this reason that I am interested in 7.5 xstream.  My experience with Vue 6 and earlier versions has taught me that what the developer promises and what you actually get are often two entirely different things and before I invest another +/- $1000. to upgrade, I would like to determine, to within a reasonable degree of certainty, that the plugin (xstream) will work in C4d R11 for Mac as advertised.  Unfortunately, either there are no users on this forum with that particular setup or there are none whom are willing to comment.  The E-on forum is even less informative in this regard than Renderosity leaving me with no possible source for an answer.  One poster had suggested downloading the demo version but there does not appear to be a demo for 7.5 xstream.

Anyway, thank you again for your thoughtful comments.
