No files appear on SD card

[ejbpesca]

OSCAR is reading my SD card a from a USB C adapter to MacBook.  When I open the SD card's icon on the desktop to view files, there are no files listed.  It appears blank.  I have no files to drag and drop yet OSCAR reads files and produces daily reports.

Any thoughts why my SD card appears to be blank?

Thank you.

Does nothing show up in Finder? It should show the name of the SD card in the left panel...

macOS Ventura introduced some new security features for USB devices. See if any of these issues are applicable: https://www.apneaboard.com/wiki/index.ph...a_13_users

The card's name shows up but there are no files listed even though they are present.  I switched SD cards and got the file names back.  I guess it was a bad SD card causing the file names to not appear.

Thanks,

By chance, did you format the card using your macOS system's command? It can sometimes produce problems since a FAT32 isn't native to that system. The SD association offers a free card formatting program for a Mac. Here is the link: https://www.sdcard.org/downloads/formatt...-download/

Yes, I am using Mac OS disk utility to format SD cards.  The SD card now showing files was formatted with a Mac format name, not an MS DOS one, since those formattings failed.  I am thinking once formatted by Mac OS, maybe the AirSense formats the card it again with ExFat Fat32.

Formatting SDs on this Mac is squirrelly.  I get failure to format notices often and no reason given as to why.
