Mac Rhino 8 Crashing

Hi McNeel,

I have a very simple question. I’ve asked this one before, but want to repeat it:

Will there be performance improvemnts in Rhino mac 8?
I am currently using the newest version of Rhino mac 7 (7.11) and the performance has improved.

But it is still disappointing how slow and laggy Rhino mac handles curves, hatches, dimensions and blocks. Rhino 5 mac was a marvellous piece of software with an amazing performance even on 10 year old macs. I hope with Rhino 8 we can turn back to this chapter and be able to handle curves, hatches, dimensions and blocks in a fast and efficient way. Waiting for 5 seconds after every click is neither profitable nor sexy.

You can run the TestMetal command in Rhino 8 today to compare speed. We are not at a point yet where metal is the default display technology, but it will eventually be default.

Will that be the point where performance is improving significantly?

Have you tried it? We’re already seeing orders of magnitude increases in performance.

Edit: layouts are barely working at this point. They aren’t worth testing

Shlould I be able to open a Rhino 7 file in Rhino 8 while it is still open in 7? This would be a good way to compare the performance.

You should be able to. If not, this would be a bug that we need to fix

We allow starting two separate Rhinoceros processes on the Mac?

Opening the same file with Rhino mac 8 wip which is already open in 7 finishes in two scenarios:

  1. The file starts to open but won’t finish opening
  2. The file opens but Rhino mac 8 is completely unresponsive and after a few seconds all the applications open on the mac close and you have to restart them

Rhino mac 8 doesn’t seem to work properly on my macbook pro…

Can you start Rhino 8 with an empty file?


It is fast at the beginning, if you zoom and daw. But if you select and try to do some commands, it becomes irresponsive and laggy for 30 seconds. Even with just a few curves…

Does the same thing happen if you have metal disabled?

Please try disabling maxwell and restart Rhino 8 to see if that makes a difference. I would like to eliminate this as a possible cause.

There seem to be two problems with 8 mac wip :

a) You cannot open a Rhino 7 file in Rhino 8 mac which in 7 is still open (which would be useful to compare performance on the same file)
b) With metal on it works fine (empty file) until you select some curves and try to delete them. Then the computer is stuck and sometimes only Rhino mac 8 crashes, sometimes all the open programs on the mac.

Does the same thing happen if you have metal disabled?

I’ve upgraded to macOS Monterey tis morning and the graphic performance on my macbook pro late 2016 with Rhino mac 7.7.11 has significantly improved.

The program seems to be more responsive, faster in display speed and much less laggy.
