wordpress: AppMe theme doesn’t play background video in macOS

I am using appme theme from WordPress for my project and i want to add video background for my header and with the help of facility provided in the theme, I have given YouTube video id to run. It’s running on the chrome and Mozilla but not working on mac. I am attaching mac version and the error I am getting along with message.

Haven’t added any external code. Although, when running the theme on the same mac, video background is working.

This is the theme
