Datasmith Mac C4D with preview 4.24

Apologies, I can’t find any info on this anywhere. I’m stuck on High Sierra due to Nvidia and Apple being assholes. I’ve installed 4.24 and see the datasmith button. If I click on it I’m not able to import any C4d files or any of the CAD files I have available. On C4D r20. What works with datasmith in this config?

could you solve this? having the same problem in 4.24
