If you’re having trouble loading a website within Safari on your Mac, then there are a few troubleshooting tricks to attempt. The first is just reloading the page; you’d do this by pressing Command-R, choosing View > Reload Page, or by clicking the little “reload” icon in Safari’s search bar.
If that doesn’t work, you could of course try quitting the browser completely and relaunching the page, but another possibility would be to use the (somewhat new) View > Reload Page From Origin feature, which’ll show up if you hold down Option on your keyboard with the View menu open.
As you can see, the shortcut for that is Option-Command-R, so if you’re a fan of keyboard shortcuts, you could try to remember that instead. What “Reload Page From Origin” does is refresh the page without using any caches you’ve got, meaning that you’ll be seeing a newly downloaded view. So if the problem you’re having has to do with an old cached version on your Mac, then, this’ll likely fix it! It’s worth a try, anyway.
And just so you know, you can also use the hidden “Develop” menu to remove ALL of Safari’s caches at once if you’re having trouble with multiple sites, as TMO’s own John Martellaro describes at the bottom of this article. And of course, if you STILL can’t get pages to load properly, it might be time to reboot your computer. Or is it frustrating for me to say that? I get the feeling folks might get tired of hearing that suggestion.
