Hi there. We just added Linux as direct download. Concerning MAC: Since we dont have an apple-signed dmg-file it would probably only show that the file cant open, because it is unsigned. The current indirect link (https://www.fromdarkness.net/download/mac.php) provides a workaround explanation. Since we are not able to attach that explanation here, I prefer keeping an indirect link (see above). Let us know if you have any more questions!
