Then that screen is perhaps what you want, but it will be driven by the Mac not the Arduino (and thus the lack of an Arduino interface doesn't matter). You will need something like an hdmi cable to that screen from the Mac to get the data there (I don't know Macs so can't tell you how to do that or if you can). The second video shows the screen(s) as displaying what looks like an audio level graph (like a VU meter) apparently on 4 tft type screens (which an Arduino may not have enough code space/ processor power to drive) which may be possible on an Arduino, but you then have to get the level data from somewhere in to the Arduino to display.
