I have a macbook pro with retina display 15¨ and 2 days ago I and a friend of mine installed rhino for mac from your website. The day after the installation both laptops until today have some problems with the screen. For example my friends laptop have horizontal white lines and now its even worse because she cant even open her laptop. My problem is a little bit smaller but its scares me. Every time I open my laptop a purple screen appears including the logo as well and it last for 1 with 2 seconds. . I already spoken with Apple Support Service and they told us to speak with Rhino support because they said it happened in 2 laptops that installed the same software at the same day, so probably it would be the programs fault. Has someone else similar programs?
