Hello tomakali,
Thank you so much for using our theme SuperMag.
We are not able to provide the dummy content for the Free version of theme. You need to purchase the pro version for the access of dummy content.
Please Add Some post and page and try to make the site as our demo with the help of documentation here. And have a look on this blog post as well.
Hope this documentation will help to make your site awesome.
Warm Regards,
Acme Supports
