Thank you Stephan,
In my case, it does not say that it is damaged. It just asks again for the authorization for opening it, telling me that it is downloaded from the net. 
In my Security tab in Settings, I allow apps downloaded from the Appstore and identified developers. The only other setting available is only App Store . 

What is the role of this hidden attribute, should I try the command? If it breaks Lyx how can I inverse it?

Best regards,
Murat
