Вы продолжаете сталкиваться с «Safari не может открыть веб-страницу; WebKit обнаружил внутреннюю ошибку» или код ошибки «WebKitErrorDomain: 300» при попытке загрузить веб-страницы в браузере Safari? Мы покажем вам, как это исправить на iPhone, iPad и Mac.
Устройства Apple используют механизм WebKit для отображения веб-страниц в Safari. Однако различные причины, такие как поврежденный кеш Safari, конфликтующие экспериментальные функции и неправильная конфигурация браузера, могут помешать работе механизма рендеринга, что приведет к «внутренней ошибке WebKit». Выполните приведенные ниже исправления, чтобы Safari снова заработал как обычно.
Выйти и снова открыть Safari
Самый быстрый способ исправить «WebKit обнаружил внутреннюю ошибку» Safari — принудительно закрыть и снова открыть веб-браузер. Это почти всегда устраняет неожиданные сбои и другие проблемы с WebKit.
айфон и айпад
- Проведите вверх от нижней части экрана (или дважды нажмите кнопку «Домой»), чтобы открыть переключатель приложений.
- Смахните карту Safari с экрана.
- Выйдите на главный экран и снова откройте Safari.
Мак
- Нажмите Command + Option + Escape, чтобы открыть диалоговое окно Force-Quit.
- Выберите Safari и нажмите кнопку
принудительного выхода. - Подождите несколько секунд и снова откройте веб-браузер через Launchpad или Dock.
Перезагрузите свои устройства
Если принудительный выход из Safari не устранил «внутреннюю ошибку WebKit», вы должны продолжить, перезагрузив устройство iPhone или Mac. Это должно устранить случайные проблемы на стороне системы, препятствующие работе браузера.
При перезапуске Mac убедитесь, что macOS не сохраняет ошибочное состояние приложения Safari, сняв флажок «Повторно открывать окна при повторном входе в систему».
Обновите операционную систему
Следующее исправление включает обновление Safari. Поскольку это собственное приложение, единственный способ сделать это — обновить системное программное обеспечение на вашем устройстве Apple до последней версии.
айфон и айпад
- Откройте приложение «Настройки».
- Нажмите «Основные» > «Обновление ПО».
- Нажмите «Загрузить и установить».
Мак
- Откройте меню Apple и выберите «Системные настройки».
- Выберите Общие на боковой панели. Затем выберите «Обновление ПО» в правой части окна.
- Выберите «Обновить сейчас» (или «Перезапустить сейчас», если вам нужно только завершить обновление).
Примечание. Если на вашем Mac установлена macOS 12 Monterey или более ранняя версия, откройте приложение «Системные настройки» и выберите «Обновление ПО» > «Обновить сейчас», чтобы обновить системное программное обеспечение.
Очистить веб-кеш Safari
Если сообщение «WebKit обнаружил внутреннюю ошибку» сохраняется, пришло время очистить кеш Safari.
iPhone и iPad
- Откройте приложение «Настройки».
- Прокрутите вниз и коснитесь Safari.
- Нажмите «Очистить историю и данные веб-сайта».
Мак
- Откройте Safari и выберите «Safari» > «Очистить историю» в строке меню.

Еще одна причина, по которой Safari отображает сообщение «WebKit обнаружил внутреннюю ошибку», связана с неоптимизированными или конфликтующими расширениями браузера. Попробуйте отключить их.
айфон и айпад
- Откройте приложение «Настройки» и коснитесь Safari.
- Нажмите Расширения.
- Отключите все блокировщики контента и расширения.
Мак
- Откройте Safari и выберите Safari > Настройки / Настройки в строке меню.
- Перейдите на вкладку
«Расширения». - Снимите флажки рядом со всеми надстройками и выйдите из панели настроек.
Если сообщение «WebKit обнаружил внутреннюю ошибку» больше не появляется в Safari, откройте App Store и установите все ожидающие обновления для ваших расширений. Затем повторно активируйте каждую надстройку браузера одну за другой. Если определенное расширение вызывает повторное появление сообщения об ошибке, отключите или удалите его и найдите альтернативное расширение.
Вход в безопасный режим и выход из него (только для Mac)

Webkit encountered an Internal error might be caused by the issues with the Safari browser or the device’s network configurations. Safari issues may range from a conflicting Private Relay feature to corrupt history/website data of the browser. The error occurs when you try to open a website in the Safari browser, but the browser fails to do so by showing the error under discussion (sometimes with a WebKitErrorDomain). This error is reported across all Apple devices like Macs, iPhones, iPads, etc. In some cases, other apps that use the Safari API on Apple devices (like Facebook, Instagram, etc.) also showed the error.
The following are found to be the main factors to cause the WebKit internal error:
- Outdated Device’s OS: If your device’s OS (like iOS for an iPhone) is missing the latest patches from Apple, then its incompatibility with other modules (especially Safari) may not let a website properly load into the browser, thus causing the WebKit internal error.
- Corrupt History and Website Data of the Safari Browser: You may encounter a WebKit internal error on Safari if the browser’s history and website data (like cookies) are corrupt. Due to this corruption, the communication between the browser and websites may be glitched out and cause the error at hand.
- iCloud’s Private Relay Feature: The iCloud’s Private Relay feature uses a double relay methodology to mask your IP from ISPs and websites. If the data packets exchanged between the Safari browser and the website have become corrupt due to this relaying framework, then that could result in the WebKit error.
- HTTP/3 Protocol of Safari: WebKit may show an internal error on Safari if the browser is trying to communicate to a website on the HTTP/3 protocol, but the website is failing to apply the HTTP 3 protocol properly, then that could cause communication incompatibility between the website and Safari, resulting in an internal error of the WebKit on Safari.
1. Perform a Restart of the Devices
A temporary glitch in your device’s OS could lead to the WebKit internal error on Safari or apps based on the Safari API, and restarting your devices may clear the issue.
- Firstly, restart your device and check if it is operating fine.
- If not, power off your device (like an iPhone, iPad, Mac, etc.) and remove its power cable (if applicable, like on a Mac) from the power source.
- Now power off your networking devices (like a router, Wi-Fi extenders, etc.) and remove their power cables from the respective power source.
Unplug Router from the Power Source - Then wait a minute, plug back the router’s power cable, and power it on.
- Once the router is properly powered on, power on your device (make sure to plug back the power cable if applicable), and once properly powered on, check if it is clear of the WebKit internal error.
- If not, power off your device (like an iPad) and keep it off for an extended time like overnight.
- Afterward, power your device and check if its WebKit internal error is cleared.
2. Update the Device’s OS to the Latest Build
If your device (Mac, iPhone, iPad, etc.) OS is missing its latest updates; it may have become incompatible with the other OS modules (like the Safari browser), which may lead to the internal error of WebKit. In such a case, updating the device’s OS to the latest build may clear the WebKit error under discussion. For elucidation, we will discuss the process of updating the iOS of an iPhone to the latest build. Before proceeding, connect your iPhone to a Wi-Fi network and then fully charge the phone.
- Launch the Settings of your iPhone and select General.
Open General Settings of iPhone - Now locate the Software Update option and tap on it.
Update Software of iPhone - Then check if an iOS update is available. If available, download the iOS update, and once downloaded, tap on Install.

4. Boot Your Device into the Safe Mode
If certain caches of your device are corrupt or another app/utility is interfering in the proper execution of the modules essential for the operation of the Safari browser, then that could also cause an internal WebKit error. In this context, booting your Apple Device in the Safe Mode (as some caches will reset and execution of third-party apps will be blocked) may resolve the issue. For illustration, we will go through the process of booting a Mac into its Safe Mode.
- Power off your Mac, and once powered off, power it on but immediately hold the Shift key.
Hold the Shift Key While Powering On Mac to Boot into the Safe Mode - Keep a hold of the Shift key until the login screen is shown, and then release the key.
- Then log in using your credentials and if asked to, log in again.
- Now head to the Apple menu > About This Mac > System Report > System Information > System Software Overview and check the Boot Mode.
Check if the Mac Has Booted into the Safe Mode - If it is showing Safe Mode, your Mac has booted in the Safe Mode; otherwise, retry the steps above.
- Once in the Safe Mode, launch Safari and check if its WebKit internal error is cleared.
- If so, boot your Mac into normal mode and launch Safari while holding the Shift key.
- Now head to the problematic website and check if it is loading normally in Safari.
- If not, check your Mac’s startup items to find the problematic app/utility (like an ad blocker or content blocker). If found, you may disable it or remove it from your Mac (if not essential) to clear the WebKit internal error.
5. Disable the Private Relay Feature
The private Relay feature is a privacy feature added to Apple devices through iCloud. This feature uses a double relay framework to mask a client’s IP from ISP and website. If a website is not compatible with this privacy feature or if the Safari browser is failing to parse the data packet from the relay framework properly, then that could lead to the Webkit internal error. In this scenario, disabling Apple’s Private Relay feature may resolve the issue. For elucidation, we will go through the process of disabling the Private Relay feature on an iPhone.
- Go to your iPhone Settings and tap on your Apple ID/name.
- Now head to iCloud and select Private Relay.
Disable Private Relay in the iCloud Settings of Your iPhone - Then disable the Private Relay feature by toggling its switch to the off position and restart your PC afterward.
- Upon restart, check if the phone’s WebKit internal error is cleared.

thisisunsafe
6. Disable the Private Wi-Fi Address of the Device
Apple devices are equipped with a Private Wi-Fi Address feature which allows your Apple device to connect to different Wi-Fi networks by using different Mac addresses to mask your online activity from ISPs or profiling your network activity based on the device’s Mac address.
You may encounter the error underhand if the Private Wi-Fi Address feature hinders the browser’s communication with websites. In such a case, disabling the Private Wi-Fi Address feature of the device may solve the problem. For illustration, we will discuss the process of disabling the Private Wi-Fi Address feature for an iPhone.
- Go to your iPhone’s Settings and open Wi-Fi.
- Now tap on the i (information) icon for the problematic network and disable the Private Wi-Fi Address by toggling its switch to the off position.
Disable Private Wi-Fi Address on the iPhone - Then relaunch the Safari browser and check if it is working fine.
7. Disable HTTP 3 Feature of the Safari Browser
HTTP 3 is still in its early days (despite being in development for years, but standards take decades to mature) and experimental. If the Safari browser fails to communicate with a website on HTTP/3 protocol properly, then that could lead to the internal error of the WebKit. In this case, disabling the HTTP/3 feature of the Safari browser may resolve the issue. For illustration, we will go through the process of disabling the HTTP/3 protocol on a Mac.
- Launch the Safari browser and expand its Develop menu.
Open Experimental Features of Safari - Now select Experimental Features and untick the HTTP/3.
Disable HTTP 3 in the Safari Experimental Features - Then relaunch the Safari browser and check if it is clear of the Webkit internal error.
8. Reset Experimental Features of the Safari Browser to the Defaults or Disable Them
Apple uses experimental features in the Safari browser to test new additions to the browser before making it part of the default browser installations. You may face the WebKit error if any customization of the experimental features is hindering the browser’s ability to load the website properly or if the experimental features are not compatible with the websites you are trying to visit. In this case, resetting the Safari’s Experimental Features of the Safari browser to the defaults or disabling them may solve the problem. For elucidation, we will go through the process of Safari’s experimental features on an iPhone.
- Go to Settings of your iPhone and select Safari.
- Now open Advanced and select Experimental WebKit Features.
- Then scroll down to the bottom and tap on Reset All to Defaults.
Reset All the Safari Experimental Features to Defaults - Now relaunch the Safari browser and check if it is clear of the WebKit issue.
- If not, head to Experimental WebKit Features by repeating steps 1 to 2 and then disable each option shown there.
- Now relaunch the Safari browser and check it is operating normally.
If the issue persists, check if turning off the search engine suggestions or switching to a different search engine in Safari clears out the WebKit error.
9. Clear History and Data of the Safari Browser
This error might be shown if the safari’s history/data is corrupt, and due to this corruption, the Safari browser is failing to access components essential for its operation, hence the error. Here, clearing the history and data of the Safari browser may clear the WebKit error. For illustration, we will go through the process of clearing the history and data of Safari on an iPhone. Before proceeding, back up/note down essential browser info like bookmarks, website logins, etc.
- Launch the Safari browser and head to its Settings.
- Then locate the Clear History and Data and tap on it.
Clear History and Website Data of Safari on iPhone - Now confirm to clear the data and history of your Safari browser.
- Then restart your iPhone and check if the WebKit error is cleared upon restart.
If that does not work, then check if the problematic website works fine in the Private Browsing mode of Safari. If so, you may disable all the browser extensions and enable them one by one to find the problematic one. Once found, you may disable it (if essential); otherwise, remove it from the Safari browser.
10. Create a New User on Your Device
If your user profile on the device is corrupt, that could lead to the WebKit internal error as the Safari browser fails to access the OS modules essential for the browser’s operation. Creating a new user on your device may solve the WebKit problem. For illustration, we will go through creating a new user on a Mac. Keep in mind these steps can only be taken with an administrator account on the Mac.

- Now select Administrator and enter other details (password, verify, password hint, etc.) per your requirements.
Create a New Administrator User in MacBook - Then click the Create User button and wait until the user is created.
- Once done, log out of the current account on your Mac and log in using the newly created account.
- Then launch Safari and check if it is clear of the internal error of WebKit.
If you do not want to create a new user, you may enable guest logins and check if Safari works fine in the guest account.
11. Reset Your Device to the Factory Defaults
If none of the above cleared the WebKit internal error, then the error could be a result of the corrupt OS of your device, and going through the troublesome process of resetting your device to the factory defaults may resolve the issue. To better interpret the process, we will go through the process of resetting an iPhone to its factory defaults. Before moving on, back up essential data on your iPhone and charge it fully.
- Go to your iPhone Settings and open General.
- Now locate the Reset option (you may scroll a bit) and tap on it.
- Then press Erase All Content and Settings.
Reset iPhone to the Factory Defaults - Afterward, confirm to proceed with the iPhone’s reset process and wait till the process completes.
- Once done, set up your iPhone as a new device (not restored from a backup yet), and then hopefully, it will be clear of the WebKit internal error. If so, then you may restore your iPhone from a backup.
If none of the above worked, then you may contact Apple support to resolve the issue, but you may use another browser or device to access the problematic websites during that time.
Do you keep running into a “Safari cannot open webpage; WebKit encountered an internal error” or a “WebKitErrorDomain:300” error code while attempting to load webpages in your Safari browser? We’ll show you how to fix that on the iPhone, iPad, and Mac.
Apple devices use the WebKit engine to render webpages in Safari. However, various reasons, such as a corrupt Safari cache, conflicting experimental features, and a broken browser configuration, can stop the rendering engine from working, resulting in the “WebKit encountered an internal error.” Run through the fixes below to get Safari working as usual again.
Quit and Re-open Safari
The quickest way to fix Safari’s “WebKit encountered an internal error” is to force-quit and re-open the web browser. That almost always eliminates unexpected glitches and other problems with WebKit.
iPhone and iPad
- Swipe up from the bottom of the screen (or press the Home button twice) to open the App Switcher.
- Swipe away the Safari card from the screen.
- Exit to the Home Screen and re-open Safari.
Mac
- Press Command + Option + Escape to open the Force-Quit dialog.
- Choose Safari and select the Force-Quit button.
- Wait a few seconds and re-open the web browser via Launchpad or Dock.
Restart Your Devices
If force-quitting Safari didn’t fix the “WebKit Encountered an Internal Error,” you must continue by restarting your iPhone or Mac device. That should resolve random issues on the system side preventing the browser from working.
While restarting a Mac, make sure to stop macOS from saving a buggy Safari application state by unchecking the Reopen windows when logging back in option.
Update the Operating System
The following fix involves updating Safari. Since it’s a native app, the only way to do that is to update the system software on your Apple device to its latest version.
iPhone and iPad
- Open the Settings app.
- Tap General > Software Update.
- Tap Download & Install.
Mac
- Open the Apple menu and select System Settings.
- Select General on the sidebar. Then, select Software Update on the right of the window.
- Select Update Now (or Restart Now if you only need to finalize the update).
Note: If your Mac runs macOS 12 Monterey or older, open the System Preferences app and select Software Update > Update Now to update its system software.
Clear the Safari Web Cache
If the “WebKit encountered an internal error” persists, it’s time to clear the Safari cache.
iPhone & iPad
- Open the Settings app.
- Scroll down and tap Safari.
- Tap Clear History and Website Data.
Mac
- Open Safari and select Safari > Clear History on the menu bar.
- Set Clear to all history.
- Select Clear History.
Disable All Safari Extensions
Another reason why Safari displays the “WebKit encountered an internal error” is because of unoptimized or conflicting browser extensions. Try disabling them.
iPhone and iPad
- Open the Settings app and tap Safari.
- Tap Extensions.
- Disable all content blockers and extensions.
Mac
- Open Safari and select Safari > Settings/Preferences on the menu bar.
- Switch to the Extensions tab.
- Uncheck the boxes next to all add-ons and exit the Preferences pane.
If the “WebKit encountered an internal error” message no longer appears in Safari, open the App Store and install any pending updates to your extensions. Then, re-activate each browser add-on one by one. If a particular extension causes the error message to re-appear, disable or uninstall it and look for an alternative extension.
Enter and Exit Safe Mode (Mac Only)
If the “WebKit encountered an internal error” continues to show up in the Mac version of Safari, try booting your Mac into and out of Safe Mode. That clears various forms of redundant data preventing apps like Safari from working.
Apple Silicon Mac
- Turn off your MacBook, iMac, or Mac mini.
- Turn your Mac on again but do not release the Power button; you’ll see the Startup Options screen soon.
- Hold the Shift key and select Macintosh HD > Safe Mode.
Intel Mac
- Turn off your Mac.
- Boot your Mac while holding down the Shift key.
- Release the Shift key once you see the Apple logo.
In Safe Mode, briefly open Safari and check if the WebKit error occurs. If it does, continue clearing additional forms of cached data on your Mac. If not, boot your Mac normally.
Disable the Private Relay Feature
If you subscribe to iCloud+, your iPhone, iPad, or Mac may have a feature called Private Relay active to improve privacy by protecting unencrypted site traffic. However, it’s still in beta and creates problems in Safari. So disable Private Relay and check if that makes a difference.
iPhone and iPad
- Open the Settings app.
- Go to Apple ID > iCloud > Privacy Relay.
- Turn off the switch next to Private Relay.
Mac
- Open the System Settings app.
- Select your Apple ID on the sidebar. Then, select iCloud.
- Disable the switch next to Private Relay.
Note: To disable Private Relay in macOS Monterey or older, go to System Preferences > Apple ID > iCloud.
Disable Private Wi-Fi Addresses (iPhone & iPad Only)
On the iPhone and iPad, another reason for the “WebKit encountered an internal error” in Safari is the use of private Mac (Wi-Fi) addresses. To stop that:
- Open the Settings app on your iPhone and select the Wi-Fi option.
- Tap the Info button next to the active Wi-Fi connection.
- Disable the switch next to Private Wi-Fi Address.
Disable the HTTP/3 Experimental Feature
HTTP/3 is a protocol that improves latency and load times. However, it’s only available as an experimental Safari feature and is prone to breaking things. Check if it’s active and disable it.
iPhone and iPad
- Open the Settings app.
- Tap Safari > Advanced > Experimental Features.
- Turn off the switch next to HTTP/3.
Mac
- Open the Safari Settings/Preferences pane.
- Switch to the Develop tab and check the box next to Show Develop menu in the menu bar.
- Select Develop on the menu bar, print to Experimental Features, and uncheck the HTTP/3 option.
Reset Experimental Preferences to Defaults
If none of the fixes above help, try resetting all experimental Safari features to their default settings.
iPhone and iPad
- Open the Settings app.
- Tap Safari > Advanced > Experimental Features.
- Scroll down and tap Reset All to Defaults.
Mac
Open the Develop menu in Safari (unhide it if you have to), point to Experimental Features, and scroll down to the bottom. Then, select Reset all to Defaults.
Safari Is Working As Usual Again
The troubleshooting tips above should help you resolve the “WebKit encountered an internal error” issue in Safari. Be sure to run through the quick fixes above if you run into the problem again.
Suppose the WebKit error doesn’t go away. If so, switch to a different browser like Google Chrome, Firefox, or Microsoft Edge and wait until a future iOS or macOS update permanently resolves the issue. On the Mac, you can also factory reset Safari to its default settings.
