Rhino running slow in iMac osx 10.7.5 2.7 ghz core 5

Hi all
I have a imac 2.7 ghz core i5 with mac osx 10.7.5 system
and very disappointed how slow it runs …the graphics are extremely slow

anything I can do ? to fix this.

an help please

First see http://wiki.mcneel.com/rhino/mac/reportingproblems and do everything that wiki page requests. We need to know how to reproduce what you are seeing.

Second, when you say something is slow, you are comparing it to something else. What is that something else? What hardware? What operating system? What 3D software? What 3D model? Post that model, too.

i compared it to normal windows like windows 7
but I eliminated my bootcamp because it fills up with viruses
…in the mac environment the graphics of rhino display slow
the pan move slow…

You are the only person reporting this problem.

We need a lot of information from you if we are to reproduce this and you are not providing very much information at all. We need OpenGL settings, we need models, we need directions, and please answer the questions in my first post. What 3D software are you comparing Mac Rhino to? What model are you using when making the comparison? Post that model.

If we cannot duplicate what you are reporting, we won’t be able to fix it.


Where do you know where can i find a version for Mac OS X Lion 10.7.2.?

It will be very Helpfull!
I hope you answer

You can’t. You can only run MacRhino on 10.7.5, 10.8.5, or 10.9x…


yes, very slow, I use macbook pro 2013.

When Open big file, Rhino mac running very slow, I instill Rhino window in Parallels, it very faster (open same file).

Rhino mac 518, OS x10.9.4.
