Writer process ended unexpectedly (macOS)

OK, I have tried a different adapter, and the first attempt was successful. I have marked that adapter as ‘questionable’, and will continue with the other. However, this problem is intermittent, we’ll see if it reoccurs in the future.

Also, what is the command line to run the application? I’ve always run it by clicking the icon.

BTW, the disk shows up on the desktop when inserted.

Thanks for the help!
