Importing 3ds files crashes - Mac M1 (silicon)

Rhino 7 keeps crashing when trying to import relatively simple .3ds files (exported from Sketchup). Activity monitor shows CPU at 104% so it seems to maxing out only the single core it is using, trying to offload, and then crashing.

Anyone else having ongoing issues with their Macbook M1 Pro? I’m running 16GB of Ram and 1TB memory. Even if shutting down all other programs, Rhino lags

Hi Charlotte - if you can send us one of these 3ds files, that would be helpful - send to, with a link back to this conversation in your comments.

We’ve found a lag on M1s when the Properties panel is open - please try hiding this panel, or putting it behind Layers, and see if the lag you mention goes away or is reduced.
