Safari / Win vs Safari / Mac

Recently, or rather after the release of the Safari browser under Windows , I have been testing my layout on it too. Actually, this is not difficult at all, since if it is perfected by standards and is displayed normally in Firefox, then in 99% of cases, the same picture will be in Safari.



Recently, I have a question that I have not yet found the answer. Are there any differences in page rendering between the original Safari / Mac and its twin brother Safari / Win? Are there any differences in the engine?

Is it possible to be sure, without having a Mac on hand, that the site will not crawl in front of the viewers of Yablokovodov? :)
