Images not showing in full on Mac Book Pro

I’m having a problem with my images not showing full width on my MacBook Pro. The slideshow element is showing full width but the static images aren’t. It was working fine at one time but no longer does it work. Also whenever I edit using Beaver Builder it doesn’t save, it just seems as if the it freezes up until I hit refresh on my browser. Any suggestions? I don’t know anything about how to use html or any other type of coding either.
