Solutions for issues that affect Safari on iPhone, iPad, or iPod touch are also available.

Reload the page

If a page doesn't open or finish loading, try to reload it: Choose View > Reload Page or press Command-R. If that doesn't work, press Command-Q to quit Safari, then reopen Safari and try again. If Safari doesn't quit, press Option-Command-Esc to force Safari to quit.

Install software updates

Install all available Apple software updates, which can include updates for Safari. If you installed any Safari extensions, update them as well.

Turn off Safari extensions

Even if your Safari extensions are up to date, temporarily turn them off to be sure they aren't affecting Safari in unexpected ways. Choose Safari > Preferences, then click Extensions. To turn off an extension, deselect its checkbox.

Test with a private window

A website can store cookies, caches, and other data on your Mac, and issues with that data can affect your use of the website. To prevent the website from using that data, view the website in a private window: Choose File > New Private Window.

If that works, use the following steps to remove the website's data from your Mac. The website can then create new data as needed. If it's a website that you sign in to, make sure that you know your sign-in information before continuing.

Choose Safari > Preferences, then click Privacy.
Click Manage Website Data.
Select the affected website from the list shown.
Click Remove.
Click Done.
Open the website again in a non-private browser window.

Check network settings

Certain network settings, such as those related to using a proxy server or custom DNS server, can affect access to content on the internet. Even if you haven't changed your network settings, you might have installed software that changed those settings for you.

To find out whether the issue is with the network settings on your Mac, try viewing the website from some other device connected to the same network. You can also add a new network location in Network preferences as a way to quickly reset your network settings for testing.

To find out whether the issue is with your network itself, try viewing the website after connecting to a different network.
