hashcat-047 problem with mavericks

Hiya,

i'm try running the hash cat 0.47 from a osx mavericks

uname -a :: Darwin 13.0.0

but once i open a terminal and type

./hashcat-cli64.app
-bash: ./hashcat-cli64.app: Operation not permitted

even trying with sudo

Anyone else got the same problem ? Did a search but haven't found anything like this

Thanks
