Can't launch on Mac OS Sierra

[GilDev]

Hi,
Just discovered the existence of N++ and oh my god so much memories from N came back! I had forgotten everything, the game and its name but I spent so much hours on this when I was a child…
Anyway, the nostalgia made me want to play a bit, but when I try to launch the Mac version of N 2.0 on my MacBook Pro running OSX 10.12.2, I get this (translated from French):
“Unable to open "Nv2-Mac". You should place this item in the trash”.

What is happening? Gatekeeper is deactivated.
Thanks!

Mac download for Nv2 is broken. I suggest just using the online version (http://www.thewayoftheninja.org/nv2.html) to play N.
