Website bug: the 4.1 download for mac gets a ".man" file not a ".dmg"

At that point os/x has no idea of how to handle the file. Seems that the link points to an inconsistent file??
I am unable to reach the mac download area using linux since the site blithly re-directs me to what it thinks I want to download rather than what I need…

Q: Is there a URL I can use to wget the current release for OS/X?
Q: Will renaming the “.man” file work (or is the web data downloaded not really a .dmg)?

thanks

I just tried to download a Mac version using Linux and was presented with the .dmg to save. - I was using the latest Firefox to do this.
