Software & Version: Rhino 7.0.23274.08002 (64-bit) OS & Hardware: macOS 12.4 on MacBook Pro (Intel i7, 16 GB RAM) File Details: Simple 3-D model, ~5 MB .3dm with only basic NURBS geometry. Problem: The app freezes and crashes (spinning wheel) whenever I try to move any object, even in a brand-new file. What I’ve Tried:

- Restarted the computer and software
- Cleared Rhino’s cached preferences
- Disabled plug-ins
- Updated to the latest Rhino service release  
Question: Has anyone experienced similar behavior? Are there log files I can check, or additional troubleshooting steps you recommend?

Just to make very sure, is this the same machine? It’s somewhat weird that you’d first report a 7.0 version with a very specific 2023 date on an Intel machine, and then post the `SystemInfo` for a 2024 7.38 version on an Apple Silicon machine.

I’m seeing two crash reports from you but those were about using `Make2D`.  
When the spinning wheel appears, Rhino is hanging but not crashing. You can force a memory dump that a developer could look at to see if there are more specifics, but since this is on Rhino 7 where there won’t be any more updates, that wouldn’t necessarily do much good.

Could you download the evaluation version of Rhino 8 to see if that is crashing with the same workflow?

Does it make any difference if you disconnect all external monitors and only use the laptop’s screen?

Are you also running into this when you are only working in viewports that are set to use the `Wireframe` display mode, and/or only use curves, hatches, annotations but not meshes, surfaces, SubD objects?
