Carl, This works perfectly under current macOS, but two steps are needed first: 1. Open a terminal, type in xattr -cfollowed by a space (this is essential); do NOT press return; drag the fraze executable into the terminal window, press return.
2. Still in the terminal, type in chmod +xfollowed by a space (this is essential); do NOT press return; drag the fraze executable into the terminal window, press return.
Then the program runs from the terminal command line.Out of mere curiosity, what tool did you use to compile this for all three platforms?
