hi Irma its not much traffic here at the moment as it seems, so i just sneak in
and help with my experience so far if that helps you at all.
i think its save to say that you should not worry about your specifications here too much
my macbook pro is now more then 7 years old and it still does a very good job on rhino
i have a third of your graphic card vram and half of your main memory which runs
at a much lower frequency and it still works fine.
Anti aliasing doesn’t work on macs with some of the Intel Iris Pro graphics chips. Check the Rhino website for the specs that the program runs best on.
