The problem is not the USB connector (or the port). I have 4 or 5 USB connecting cords, all of which I’ve used without incident in other capacities and, no matter which of those I use here, the result here is the same (as is the result regardless of which port on my Mac is being used).
I have a couple of questions, please:
1. Do you think my plan to set up a Windows 10 OS on my Mac, and then move my JR MC application there (along with the FLAC files) is a good solution OR might you have a better one?
2. As I am not very much at all experienced in these matters, and it now appears possible that I may need to come back to this forum for follow-up assistance, would it be possible for you to share with me the names of Card Readers you have used, so that I can use one of them, so while we continue to try and find a solution, we can henceforth, with some confidence, rule out the Card Reader as the source of a problem?
Thank you for your patience and consideration.
