Safari usually fails to load web pages because of a network problem, a temporary browser error, outdated software, corrupted website data, or an extension that interferes with browsing. Start by testing another website and another app that uses the internet. Then restart Safari and your Mac, check your connection, install available updates, and clear Safari’s website data if the problem continues.
Quick Answer
Try these fixes in order:
- Reload the page and test a different website. 2. Check whether other apps can access the internet. 3. Quit and reopen Safari, then restart your Mac. 4. Turn off Safari extensions temporarily. 5. Clear data for the affected website or clear Safari’s history and website data. 6.
First, Identify What Is Failing
Before changing Safari settings, determine whether the problem affects one page, several websites, or the entire internet connection.
Test another website
In Safari, open a new tab and visit a reliable website you do not normally use. If the second site loads:
- The original website may be temporarily unavailable.
- The page may have a broken link.
- Safari may have stored corrupted data for that site.
- A Safari extension may be blocking part of the page.
If no websites load, continue with the connection checks below.
Test another internet app
Open an app such as Mail or the App Store and see whether it can connect. You can also try another browser if one is installed.
- If no app can connect, troubleshoot the Wi-Fi, Ethernet, VPN, or router connection.
- If other apps work but Safari does not, focus on Safari settings, extensions, and website data.
Restart Safari and Your Mac
A temporary Safari process or network service may be stuck. Restarting can clear the problem without changing your files or settings.
- Save any information in open web forms.
- In Safari, choose Safari > Quit Safari.
- If Safari does not close, press Option-Command-Escape, select Safari, and click Force Quit.
- Open Safari again from the Dock or the Applications folder.
- If pages still will not load, choose Apple menu > Restart.
Warning: Force quitting Safari can discard unsaved text, uploads, or other information on open pages.
Check Your Internet Connection
Safari cannot load pages if your Mac has lost network access, even if Wi-Fi appears connected.
Check Wi-Fi or Ethernet
Open Control Center in the menu bar and check the network connection. If you use Wi-Fi, disconnect and reconnect:
- Open Control Center.
- Click Wi-Fi.
- Turn Wi-Fi off, wait a few seconds, and turn it on again.
- Select your network if necessary.
For Ethernet, confirm that the cable is firmly connected to the Mac, dock, or network adapter.
If other devices on the same network also cannot browse, restart the router or modem according to the manufacturer’s instructions. Contact your internet service provider if the outage continues.
Disconnect a VPN temporarily
A VPN routes your web traffic through another server. A failed VPN connection or restrictive VPN setting can prevent pages from loading.
Open your VPN app and disconnect temporarily. If the page loads afterward, check the VPN’s server, filtering, and split-tunneling settings. Reconnect the VPN when testing is complete.
Warning: Disconnecting a VPN changes how your internet traffic is routed and may reduce privacy or bypass protections provided by your organization. Re-enable it after testing.
Check for a proxy
A proxy sends web traffic through an intermediary server. An incorrect proxy can make Safari appear offline.
- Choose Apple menu > System Settings.
- Click Network.
- Select Wi-Fi or Ethernet.
- Click Details next to the connected service.
- Click Proxies.
- Review the enabled proxy options.
Do not turn off a proxy if your workplace, school, or organization requires it. Ask the network administrator for the correct settings.
Check Safari Extensions
Extensions can block ads, scripts, cookies, pop-ups, or entire domains. An update to a website or extension can also create a compatibility problem.
- Open Safari.
- Choose Safari > Settings.
- Click Extensions.
- Select an extension and clear its checkbox to disable it.
- Reload the affected page.
Disable extensions one at a time if possible. When the page begins working, the last disabled extension is a likely cause. Update or remove that extension, then re-enable the others.
If you use content blockers, temporarily disable them for the affected website rather than disabling every privacy tool permanently.
Open the Page in a Private Window
A Private Window uses a separate browsing session and can help determine whether saved cookies, cached files, or website data are causing the problem.
- Open Safari.
- Choose File > New Private Window.
- Enter the website address.
If the page loads in the Private Window, saved website data or an extension is probably involved. Extensions may still be active in private browsing if you have allowed them to run there, so this test is useful but not conclusive by itself.
Clear Website Data
Safari stores cookies, cached files, and other data to remember logins and load pages faster. If that data becomes damaged or conflicts with a website update, the page may fail to load.
Remove data for one website
Removing data for a single site is the least disruptive option.
- Choose Safari > Settings.
- Click Privacy.
- Click Manage Website Data.
- Search for the website’s name.
- Select the related entries.
- Click Remove, then click Done.
- Quit and reopen Safari, then try the website again.
Warning: Removing website data may sign you out of that site and delete saved preferences or locally stored website information.
Clear all browsing data
If several websites fail or you cannot identify the affected site, you can clear Safari history and website data.
- Choose Safari > Clear History.
- Select an appropriate time range.
- Click Clear History.
Depending on the selected range and Safari settings, this can remove browsing history, cookies, and related website data.
Warning: Clearing all history can sign you out of websites and remove browsing records you may want to keep. Use the smallest time range that addresses the problem.
Check Safari’s Privacy and Security Settings
Some sites require JavaScript, cookies, or pop-ups to function correctly. Privacy protections are useful, but overly restrictive settings can break login pages, payment pages, embedded content, or web apps.
- Choose Safari > Settings.
- Click Security and review settings related to JavaScript and fraudulent website warnings.
- Click Privacy and review cross-site tracking and IP address settings.
- Click Websites to review permissions for the affected site.
Do not disable security warnings simply to make one page load. If a website asks you to weaken important protections, consider using a different site or contacting the website’s support team.
For a specific site, click Safari > Settings for [Website Name] when that option is available, then review permissions such as camera, microphone, pop-ups, downloads, and content blockers.
Check Your Mac’s Date and Time
Incorrect date and time settings can cause secure websites to reject your connection. This happens because encrypted connections rely on valid security certificates.
- Choose Apple menu > System Settings.
- Click General.
- Click Date & Time.
- Turn on Set time and date automatically if it is available.
- Confirm the correct time zone is selected.
Close and reopen Safari after correcting the settings.
Update macOS and Safari
Safari is updated through macOS, so installing available system updates can fix browser bugs, security issues, and compatibility problems with newer websites.
- Choose Apple menu > System Settings.
- Click General.
- Click Software Update.
- Install any available update.
- Restart the Mac if prompted.
Save your work before installing updates. The Mac may restart, and open apps may close. If you want a more detailed checklist for preparing and installing updates, see How to Update macOS Safely.
If the Mac is managed by an employer or school, software updates may be controlled by an administrator.
Check for DNS Problems
DNS translates a website name, such as example.com, into the server address needed to connect. If DNS is unavailable or returning incorrect information, Safari may show an error even when Wi-Fi works.
First, try opening the site by its normal domain name in another browser. If several browsers fail to find websites, DNS may be the cause.
You can restart the network service by disconnecting and reconnecting Wi-Fi. You can also restart your router. Avoid changing DNS servers unless you understand the effect or have instructions from your network administrator or internet provider.
Use Terminal to Test the Connection
Terminal can help distinguish a DNS problem from a general connection failure. These commands only test connectivity; they do not change files or system settings.
- Open Terminal from the Applications folder.
- Run this command, replacing the domain with the affected website:
ping -c 4 example.com
This sends four basic network requests. If you see replies, your Mac can reach the domain at a basic network level. If every request times out, the website may block this type of test, or your network may be unable to reach it.
- Test DNS resolution with:
nslookup example.com
This asks the configured DNS server for the website’s address. If it returns an address, DNS is responding. If it reports that the server cannot be reached or the domain does not exist, investigate the network or DNS settings.
Stop a command that continues running by pressing Control-C. No reversal is needed because these commands do not alter your Mac.
Check Security Software and Parental Controls
Antivirus tools, firewall utilities, content filters, parental controls, and enterprise security software can block specific websites or web technologies.
Review the security app’s event log or website-filtering settings. If you must test by disabling a feature, do so briefly and only if you understand the risk.
Warning: Disabling security software reduces protection. Re-enable it immediately after testing, and do not leave a Mac unprotected while browsing or downloading files.
If the Mac belongs to an organization, contact its administrator rather than changing managed settings.
Troubleshooting Specific Safari Errors
“Safari Can’t Open the Page”
Check the web address for typing mistakes, then try the page again. Test another website to determine whether the problem is limited to one domain. Also check VPN, proxy, and DNS settings.
“Safari Can’t Establish a Secure Connection”
Verify the Mac’s date and time. Then update macOS and Safari. If the error affects only one website, its security certificate or server configuration may be invalid.
Do not bypass certificate warnings on sites that request passwords, payment information, or personal data.
A blank page appears
Disable extensions and content blockers, then clear the affected site’s data. Test the page in a Private Window and another browser. A blank page can also result from blocked JavaScript or an outdated website application.
The page loads but buttons or media do not work
Review website permissions, JavaScript-related settings, extensions, and content blockers. If the problem occurs only with one service, the site may require a browser update or may not support your current configuration.
When Safari Works in Another User Account
If Safari loads pages normally in a different macOS user account, the issue is probably limited to your account’s Safari data, extensions, or network settings.
Create a temporary account in System Settings > Users & Groups, sign in, and test Safari there. Delete the temporary account afterward if you no longer need it.
Warning: Creating or deleting an account changes local user data. Do not delete an account until you have copied anything important from its home folder.
When to Contact Apple or the Website
Contact the website’s support team when:
- Only that website fails.
- The site fails in multiple browsers or on multiple devices.
- The site displays a server, certificate, or account error.
Contact Apple Support or an Apple-authorized service provider when:
- Safari fails for every website after network troubleshooting.
- Other browsers also fail while the network appears healthy.
- The Mac has repeated system crashes, network disconnects, or unusual security warnings.
Frequently Asked Questions
Why does Safari work in a Private Window but not a normal window?
Saved cookies, website data, cached files, or extensions may be interfering with the page. Remove data for that website first, then test your extensions individually.
Why does only one website fail in Safari?
The website may be offline, misconfigured, blocked by a content filter, or incompatible with a Safari setting. Test it in another browser and on another device before changing major Mac settings.
Will clearing Safari history delete my bookmarks?
Clearing history does not normally delete bookmarks. However, it can remove website data and sign you out of sites, so use the smallest available time range.
Can a VPN prevent Safari from loading pages?
Yes. A VPN can block a domain, use an unavailable server, or conflict with local network settings. Disconnect briefly to test, then reconnect it after troubleshooting.
Should I reinstall Safari?
Safari is integrated into macOS and is not normally reinstalled as a separate application. Updating macOS, removing problematic website data, and checking extensions are better first steps.
Final Thoughts
When Safari cannot load web pages, first determine whether the failure affects one site or the entire connection.
