Safari blocking cookies

If Safari doesn't open a page or work as expected on your Mac - Apple Support offers a number of suggestions.

The reason a Google screen appears is odd though. Is it always the same screen? Can you describe it, or post a screenshot of it? Please do not post any personal information.

Is only the Google website affected?

Did you follow its instructions to "clear your browser's cache and cookies" as well as its other recommendations? All I know so far is that you enabled cookies.

If the problem is isolated to that specific website, perhaps it just isn't working properly.

If everything you describe is accurate, and you exhausted all the options in the Apple Support document I referenced, then the website is defective. There is no other explanation.
