Olympus .ORF files not showing thumbnail preview in Finder, but it shows when I press SPACE

Hi there,

I have ORF files from an Olympus OMD EM-1 mk2 and mk3 that don't show the thumbnail preview in Finder. The camera is supported.

If I press "Space" or if I view the folder in "Gallery" mode the thumnail shows up without issues, but only a generic icon appears as the thumbnail.

Computer is 14" Mac M1 with 64GM Ram and 8TB disk.

I have a different Mac M1 16" that shows the thumbnails without issues, and I can't remember if I installed a different software to get it working.

Any help or tips? Thanks in advance!
