Almost solved... The card does show up as "Untitled" on the desktop, but not in the LOcations window on the RHS in Finder. STill counts as a bug in my book, but more likely Apple's than Fuji's.

I just ungraded to Big Sur (from Mojave). The SanDisk 32GB card from my Canon mounts fine in my USB card reader. The same model card coming from my Fuji X-T30 does not show up in Finder. The Mac knows it is there, because when I remove it from the card reader I get the message ["" was removed without dismounting]. The card used to show up as Untitled (or similar) under Mojave but now it doesn't show up at all. (The Canon card gets a name from the camera when it is reformatted). I know I could name the card in the computer, but the name would be wiped on formatting. Does anyone know of a workaround, r if Fuji is revising the firmware to assign a name to the cards? (The card does not even register when inserted into the slot in the back, but that's something I never use)
