The mac download does not work. I'm getting:
“Magic Frontier” is damaged and can’t be opened. You should move it to the Trash.
Unfortunately this is due to the newer Mac OS code signing requirements. I currently lack the tools to do signing. There is a workaround to this problem if you are familiar with the Terminal: https://osxdaily.com/2019/02/13/fix-app-damaged-cant-be-opened-trash-error-mac/
Regardless, thanks for giving it a try!
