Never call callback on Mac os #91

Hello,

I've got a problem on Mac OS. Here is my code :

...
.then(function() {
    var opn = require('opn');
    return opn(url);
})
.then(function() {
         MessageService.success("Document ouvert");
         return;
     });

It works fine on Windows, but on Mac OS, the callback (messageService.success ...) is never called.

Can anyone help me ?

Thanks
