If a single website is loading incorrectly in Safari, clearing your entire browser history is overkill. You can surgically clear the cache for just that one site.
How to Clear a Specific Site’s Cache
- Open Safari on your Mac.
- Go to Safari > Settings > Privacy.
- Click the Manage Website Data button.
- Use the search bar in the top right to find the broken website.
- Select the website and click Remove, then click Done.
