You could try deleting the hidden resource files that MacOS copies onto the SD card because it’s FAT32.
Open Applications/Terminal.
Type cd (that’s cd with a space), then drag the SD card icon onto the Terminal window to auto-fill the path. Hit return.
Type cd common to go into the common folder.
At this point, if you type ls -al you should see a directory listing of all the Voicepack files and folders, including invisible ones that are the same names but start with a dot.
These are what you will remove next.
Type cd .. to go back up one level to the root of the SD card.
CONFIRM that the prompt says the path to the SD card root, something like /Volumes/SDcardName
Then type (or copy and paste this)
find . -type f -name '.*' -delete
Doing ls -al again now should show the files and folders starting with a dot are gone.
You can cd common and list the contents, should have just the actual sound files in there.
Put in Proffieboard and test.
