Rhino V6 Mac Performance

Hi, I’m really close to despairing with Rhino’s performance on my Mac. I recently bought a new 2019 16" MacBook Pro and I thought this would solve some of my issues due to better CPU and added GPU. But Rhino does not really feel much faster and often so slow that it becomes a pain to use.

One issue I’m experiencing right now: I have a 2D plan .DWG file that I want to use as basis for my 3D geometry. I open it in Rhino and removed some layers to get rid of unnecessary geometry – so far so good (even though selecting curves is already slow). Then I scale it by 200 to get it to actual size. After that it’s beach ball only and the file becomes completely useless.

I read in another thread that there are performance issues with “far from origin” geometry. So I thought changing the units from cm to m without scaling the geometry would help. And I think it did in the original file. But when I try to use that file as a block in another file – beach ball and no chance of doing anything in Rhino.

Any idea how I can make this work? I am attaching the 3DM file that I made from the original DWG file.Plan EG 200131 minimal.3dm (12.1 MB)

When it comes to lots of curves RH6 on Mac seems to perform very bad (worse than RH5 on Mac apparently).

Here is a thread, where we already discussed this issue:


hey @rudolf.neumerkel, thanks for your response. So from what I understand there isn’t a real solution to this other than switching to V5 or waiting for the developers to fix it? :unamused:

However, I want to stress that the original file works ok – it’s just after scaling that the file becomes unusable. So it’s not really the amount of curves that is causing the issues… but I have no idea what is

I guess sending the file to tech support might help them to diagnose the problem…

I think 6 and 7 mac have big performance issues. 2d drawing, material editor, Layouts. They feel insanely laggy, even on small files. I swithed to 7 wip because it feels slightly faster. But still far away from 5, which is fast even on my 15 year old wrecks, which I do not use anymore.

I use on my macs AutoCAD, Affinity Photo Designer Publisher, AD Lightroom, Blender etc. No performance issues at all. Only Rhino 6/7 gives me big trouble.

As written above I dumped 6 because I do not see any point in using it. I started a thread some days ago

Thanks for your Feedback @OXII and @Helvetosaur. I uploaded the file to tech support and will post an update if there is a reply. So it might be a solution to go back to Rhino 5? I don’t think I want to do that though, having 2 programs installed with different features and all seems like a less than optimal solution. Also I don’t really want to use WIP for critical projects… Thanks anyway!

Go bootcamp, it will solve your issues.
Performance on Win vs Mac is beyond compare. I’m having this setup for 3 years now, second MBP, I know what I am talking about.

I hadn’t considered that option yet. I don’t have bootcamp/Win installed so far but I’ll look into it. I think I would actually prefer this over having another version of Rhino installed or using the WIP

Fun fact: I’ve actually gone back to drawing plans in Adobe Illustrator because of the poor performance of Rhino in this feature :roll_eyes:

Mamma mia. I hope McNeel is able to fix this problem. Macs are so convenient in a professional design environment and actually cheaper to run in a design office.

I can repeat this and am investigating the cause. Thanks for the report and sample model.

This is not a Mac specific issue. I can bring Windows Rhino to its knees with this model as well. There are custom hatches in this model that result in a ton of tiny lines and scaling by 200 blows up the number of lines to a number that Rhino can’t handle.

Here’s what you can do while we figure out a way to improve this in Rhino

  • Open your model
  • Run SelHatch to select all of the hatches in your model
  • In the hatch properties panel change the scale to 200 for all of these hatches
  • Run the Scale command to scale your model by 200

My suggestion to the users is to switch to 7mac beta. It gets better and better, performance is improving from version to version.

We import a lot of dwg files and do also all the 2d execution drawings in Rhino. It works well. Only the responsiveness and speed is not as fast as we would like it to be. It still feels laggy and slow after a few lines and hatches and some imported dwg reference.

With 7 (first wip and now beta) it has gotten better and better over the last months. Initially it was not unusable because of poor performance. Now it is already way better, but it would be great if it still gets improved in performance.

Hi -

Without necessarily commenting on the performance on a Mac, it would be interesting to get such sample model to test it on Windows. It doesn’t take much of “some imported dwg reference” to completely slow-down the Windows version as well…

I finally upgraded my Macbook Pro last summer. I was using a 10-year-old MacBook Pro until then.

I never had any performance problems with Rhino on that ten-year-old machines. I’d still be using that machine for Rhino if the keyboard had not worn out and I could not get it replaced.

I have never had any performance complaints with my 1-year-old machine.

In both cases, I got the best graphics card and maxed out memory.
