Good morning,
I installed and uninstalled virtualbox lot of times, and searched a lot in the web, but i can't find a solution.
I think i correctly add the permissions (i'm not an experienced mac user).
When i launch the app, i notice a little movement in the dock, like an app that starts but it's killed in a second.
When i launch it using Spotlight, an alert appairs with the message [ The application "VirtualBox" can't be opened ]
When i launch it from the Applications folder, the alert does not appair.
I don't know how to give you more details, please tell me how can retrive them, so i can provide them to you.
Thanks a lot.
OSX Sierra 10.12.6
VirtualBox 5.2
