Maxon developers need to update some things given that Apple revised the way in which thumbnails are created.

Hey guys,

I'm on a m2 MBP (Sequoia 15), with the latest c4d (2025) .

Whereas files would show the thumbnails with a preview of the file model or whatever on earlier version of c4d, c4d 2025 now shows just the c4d icon.

I really would like to have the preview, (don't follow good naming/file organization schemes... it's practically impossible for me to work without this).

Any idea how I can get the file preview thumbnails back?
