Rhino 8 Mac performance and stability issues

Dear McNeel developers,

I have been looking forward to an update of Rhino for the Apple silicon chips for two years and was surprised how fast it went from a Beta to the full release which I have bought right away.

After having it used intensively for approx. 4 weeks, I’m shocked how many crashes, random lags, and UI bugs I have encountered.

Just to name a few (for all crashes I have submitted a crash report)

  • When working with multiple files and switching between back and forth it often happens that when continuing to work in the window in front and clicking it jumps back to the former window which is being “displayed” in the back or a tooltip from hovering above an UI element stays and keeps showing up on top of the new window

  • When trying to to right click on a layer or renaming by double clicking, it just doesnt work. Waiting or changing the app or cursing the programme seems to do the trick.

  • Sometimes when panning/orbiting in the perspective view port ( mostly rendered) there’s a lag of a bout 2-4 seconds with beach ball for no apparent reason

  • Copy and Paste of the same object into the same file takes too long than it should, even with small objects such as some simple extrusions

  • Rhino 8 freezes and needs to be forced to quit a lot. Today already 4 times. I have never had such problems with Rhino 6 on Mac or 7 via Parallels on the M1 chip.

  • One file just randomly crashed after sucessfully exporting an STL file, then the other two files that were still open got the beachball and had to be forced to quit

That’s just what I can remember from the top of my head. I’ll keep adding as more crashes are likely to happen.

It seems to me that Rhino 8 for Mac is unfortunately not more than a Beta with still a lot of issues to be fixed.

Any help or tip is. appreciated. Please bring back Rhino on Mac to its full power.

hi @ice first of all, thanks for reporting the issues and sending in the crash reports. If you can share the file(s) that demonstrate these issues, that would be helpful. Confidential and/or too big files can be sent here

I created new topics for all issues you have reported, to keep things better trackable.
