Mac: Opening download problems

How can I fix this?

EDIT: I did set my security preferences to “Allow downloads from anywhere”, not just the Mac App Store.

EDIT 2: I got through it, but now there’s another problem.

I’m having the same problem trying to figure out whats wrong as well because I got a new mac and can’t figure out the 2nd problem.

For the “The application X11 could not be opened : Failed to activate core devices”? Try this?

Thanks, but now it just says that the Mac can’t open the application. It just auto quits.

Still doesn’t work for me because it now just auto quits before anything pops up.
