Change Websites settings in Safari on Mac

In the Safari app  on your Mac, use Websites settings to customize how you browse individual websites.

To change these settings, choose Safari > Settings, then click Websites.

The settings you can customize (such as Reader and Content Blockers) are listed on the left.

To apply a setting to a website on the right, first select the setting, then choose the option you want from the pop-menu next to the website.

If you want to customize settings for each website in Safari on Mac, please check out this link as well, which will guide you through that process: Customize settings for each website in Safari on Mac

Thanks!

Hey there Yungyyyy, 

At this point, you'll want to contact Apple Support for assistance.  

Have a good one!
