My After thoughts are that the MacBook Pro its a great laptop for web browsing some video editing, but still these MacBook’s lack a strong GPU for people who also want to do some Gaming. Another issue that I should mention is that heat is a problem on such s small computer as a result you will hear the fans spin up quite high when the laptop is under load. I have added these details in the video so you can hear the back ground noise that they make.
Mac OS Mojave light or dark featureis pretty cool too, it allows you to set your Mac OS to light or dark mode.
