Carrara 8.5.1.19 appears to be working nicely on mac 10.10.3. Now if they could just go get Bryce into working! I miss my Poser/Bryce/Carrara workflow. I have not spent much time trying to work with Gen 2 in the Carrara update much as yet, but it is loading them up rather nicely so far; however,  I do keep finding breaks in the texture seams most often right at the thighs.
