[Ifeffit] ifeffit on Mac 10.8.5

[Gaspard Jean-Pierre]

Hello,

I am working on a MacBook under OS X.8.5

I downloaded iXAFS.

When I try to start iXAFS, the system answers (in French):
"Impossible to open because it comes from an unidentified developer."
In the new OS, it is difficult to start an application that is not validated by Apple.

Is there a way to start iXAFS ?

Thank you for your help.

Regards
