I think it’s been half a decade since the last time Safari for Windows was updated.
Are you suggesting there is a Windows version of Safari? I don't think that's true anymore unless something has changed recently.
You're both right in that Safari for Windows hasn't been updated in years, which is why I said that the Mac version is way more modern. However, Safari for Windows does still exist, no matter how old and incompatible it is. For Windows, I would probably go with Chrome at this point, but I haven't really tried Edge, so that might be a worthwhile option as well.
