Just seems to be super flakey and inconsistent.
These are all Sandisk Ultra cards, both XC and HC, that were formatted in my camera.
I tried reformatting them w/ the MBP and that didnt seem to make a difference.
All my cards work as expected in my 3 other USB card readers.

I have a fairly new 64GB SD card which had been working fine.
Sometimes the Finder crashes too.
However, the same format works fine with an external USB pop in-C adapter.
100% of my cards work perfectly via a dongle.
