BlueBoard software cannot run because "/mnt: No such file or directory" I have connected BlueBoard to Mac. While running program with use of Terminal I receive this error. How can I resolve this?

mount -t FAT12 /dev/disk2 /mnt
mount: realpath /mnt: No such file or directory
make: *** [program] Error 1
macOS doesn't have a /mnt directory/folder (it's not Linux)

You can fix this by mounting in a directory that you have read/write permissions to like your home folder.  Just make sure you create the directory first.
