@Tim Berglund Use EditReady or optimize the files upon import until Apple issues an update. Also, it’s always a good to search for the relevant thread before posting a new one, ie
Absolutely searched before posting. Did not find that post. Thanks!

Some of the files I shoot on my GH5 can be previewed in Mac OSX Finder, and some cannot. Specifically, if I shoot 2160p24 (4:2:2, 10-bit, Long GOP), Finder is not pleased, and if I shoot 2180p60 (4:2:0, 8-bit, Long GOP), Finder is pleased. Looking at the metadata of the Quicktime files, I they both claim to be H.264, but Finder treats them differently. I can preview the 24p files in VLC, but it's a bit of a workflow bummer. I like to tag files in Finder, but can't for 24fps footage.
I'm not looking for a fix here, but does anyone have any insight into why this is so? These are all H.264 Long GOP files, right?

Axel, that is ridiculously helpful, thank you.
I edit with Premiere, which happily* gobbles up the 10-bit files these days, so I can manage to edit them in the end. It's just hard to sort through footage before I import.
I was thinking of using Adobe Media Encoder to transcode everything to ProRes LT (which is around the same bitrate as the in-camera codec—perhaps a little bit higher), but now that I understand that the problem is bit depth and not anything else about the codec, that transcoding step might not be my friend. If I have to transcode from 10 bits to 8 bits, I am giving up bit depth, even if I keep overall bitrate constant. The question is whether I will really feel that difference when grading difficult shots or in final picture quality, since realistically my delivery will always be Vimeo or YouTube anyway.
I suppose the final answer, barring changes to my workflow, is to wait till Finder supports 10-bit files! (For posterity, here is a link to an Apple support forum confirming the 10-bit limitation.)
*As happily as it does anything! It likes to crash, and I am editing on an underpowered machine for this footage for sure. Ultimately proxies FTW, but that's later in the workflow.
