Why would I need to format to a macOS filing system? I’ve never once in the last 30 years needed to use an Apple computer to accomplish something. But that definitely isn’t the case for Apple computer users. Even Apple realizes this which is why they have Boot Camp as part of their operating system so you can run WIndows applications inside macOS and they also allow you to format to a Windows based file system.
It would help hifiml1 if you would kindly post instructions on how to format to FAT16. I strongly suspect a less than optimally formatted SD card is the root of his problem.
Here’s how to do it within macOS:
Apologies. I’ve never been Terminal guy/coder particularly, as I didn’t need to. I am at the veterinarian getting my dog x-rayed.
Yike.
Wow, if that isn’t ironic. I’m at the vegetarian clinic getting my hot-dog exiled.
For sure the cards must be the problem. I found a “no brand” 2GB card and formatted it with my Macbook, and this time it all went fine. The same card is now deleted and in the DAC, and the cover art is also working.
The other two cards is the cards I have been using for only this purpose since I bought my DS Sr.
Thank you guys for all help. This forum must be a big help for Paul and his service-team.
Congrats 
Although I appreciate inter platform rivalry, my IT background and my feeble old mind tells me that neither Microsoft or Apple can lay claim to the Graphical User Interface (GUI) it was PARC LABS/XEROX.
DOS, talk about your good times. 
Pretty soon I’ll be reminiscing about Windows 3, Netscape, bulletin boards and something called America Online.
Oh, I forgot key punch cards, a PDP 11/70, Prodigy, dumb terminals and emulation machines, modulaters and demodulators, the evolution of the personal computer when working at Citibank and a bunch of other stuff.
Keep dating myself.

“dog” is not a euphemism, in case some of your minds were going there… ; )
56k Modems!
Great news.
But odd that you appear to have had problems with the SD cards themselves, especially more than one. They tend to be pretty robust.
Did you use the Mac’s default FAT32 formatting?
No, not to suggest they invented it, just that Windows is “just a bit” of an emulation (I’m holding my index finger and thumb apart as far as they can go…and I have…Really Big Hands), and when I’ve listened to the Windows v.Whatever horror stories over the years, I’m perfectly OK with the fact that I can’t easily format FAT 16. (Bam! Drops Mic)
All that is only because Microsoft won that Betamax/VHS war, not because it’s better ; )
No more mic drops!
These make me cringe, even if it is a lowly tank-like SM58.
It’s the only mic I would do it with, and not my modded one, either. Wouldn’t do it with a 57 for some reason. I guess because it might break the plastic housing around the spit screen on a 57.
The SM57 is the instrument version of the SM58 (you know this). Shure expects us instrument players to be nicer with things than those careless vocalists. 
As a related aside, I can leave a couple of trumpets on stands at my chair when the orchestra takes a rehearsal break and know they will never be touched by another musician, much less knocked over.
But if there is a choir involved, put your instrument in its case, take it along, whatever - the chance of it getting damaged has gone up exponentially.
Some vocalists prefer them over the 58 either for their tone with their voice, and/or their narrower directivity/potential for less stage monitor feedback. Tom Petty comes to mind.
I find a mild karate chop to the larynx helps to wake the average clueless vocalist up with regard to the disrespecting and damaging of tools and instruments ; )
I’ve never actually HAD to do anything with anything other than the Mac environment, but I’ve worked for myself most of my life in an industry in which it is the preferred computer, and on which most of the best software runs.
I’ve often had to tell my Windows clients how to do basic things with their computers with regard to A/V (the Presentation is in 3 minutes!! Can you make my Powerpoint display on the projector!?!?), etc.
We all use the tools that are best for our jobs, or that we are compelled to use for one reason or another.
