How can i get my Olympus Raw files to be supported in OS 10.14.6?

My Olympus raw file taken with OMD-em1 Mark III do not work with the apple finder. I NEED to see them for use with an older catalog app, Expression Media. I believe they will do this once apple upgrades and supports them in its finder. I also read that these new raw files (ORF) are not supported by PHOTOS app. This is a new type of raw file which Olympus EM1- Mark III. creates. (And I assume the same type as the newer OMD creates.) My Mark I raw files work fine in 10.14. How can I be notified if and when Apple upgrades OS 10 to support this type of raw file. I can open these raw files in Photoshop, and I read also in some other apps, but I also need it to work with the finder and Apple apps
