Currently you can't view the new Sony A7S3 thumbnails (RAW) on Macs / Macbooks OS Catalina - big problem.

This might seem like a trivial issue, however, for those of us who do large volume shoots in our profession (I'm a real estate photographer)- this is major issue when it comes to efficient work-flow.

I shoot 5-brackets, an average of 300 brackets / photos per home, averaging four homes per day, five days per week. I have to get my photos sorted at the end of the day and then processed or uploaded to my editor so I can have them back to my clients next day. That's 1500 photos per day, in which I have to choose the best 35 photos (175 brackets) to send to my clients. Without Finder, to have to load them in Lightroom, then click on each individual bracket within a set of five, - it could take hours. With using finder, you can split the window and quickly drag and drop to your upload folder. The entire process for one home is about 10 min vs 45 min. Any help or workaround ideas would be appreciated.
