Hello arimk81,


​Thanks for asking your question here in the Apple Support Communities. I actually believe you are experiencing issues with YouTube because of a separate issue.

The reason I believe you are experiencing issues is that Adobe Flash Player, Java, and Silverlight are off by default in Safari for macOS Sierra. You can enable them using the steps in the following article:

Thanks again and have a great rest of your day.
