There may be many reasons why an Apple computer has an Internet but can't open a web page, and here are some common reasons and how to deal with them, as well as things to pay attention to.
1. Possible causes
1.DNS setting error: DNS is a domain name resolution system, if the setting is incorrect, it may not be resolved**, so that the web page cannot be opened.
2.Server setup issues: If you have set up a server on your computer, and the server is faulty or misconfigured, it will also cause the web page to not open properly.
3.Browser issues: Browser plug-in conflicts, excessive caches, or outdated browser versions can cause web pages to not load properly.
4.Network firewall or security software blocking: Some firewalls or security software may misjudge certain network requests and block them, causing web pages to not open.
5.System network configuration issues: If there is a problem with the network configuration of the Mac computer, it may also cause the web page to fail to open.
Second, the treatment method
1.Check DNS settings: You can access the advanced settings by clicking on the System Preferences icon on the Dock at the bottom of the desktop, finding and tapping on the WiFi or Ethernet option in the network settings, and then clicking on the "Advanced" button in the bottom right corner of the window. On the DNS tab, view and modify the DNS server address. You can try using a public DNS server address, such as Google's public DNS (88.8.8 and 88.4.4) or public DNS, etc.
2.Check Server Settings: Find Network Settings in System Preferences and check if the server is set up. If you set up a server, try unsetting the server and then reconnect to the network.
3.Check your browser settings: Clear your browser cache, disable unnecessary plug-ins, or try using a different browser. At the same time, make sure that the browser version is up to date to avoid compatibility issues.
4.Check your firewall or security software settings: To make sure your firewall or security software isn't misnecessitating network requests, you can try turning off your firewall or security software temporarily and then reloading the web page.
5.Restart your PC and network devices: Sometimes, restarting your PC and network devices can resolve network configuration issues.
3. Precautions
1.When modifying network settings, be cautious to avoid misoperation that may cause the network to be unable to connect. If you're not sure how to modify your settings, it's a good idea to consult your network administrator or professional first.
2.When using a public DNS server address, make sure that it is reliable and avoid using an unknown DNS server address to avoid risks such as cyberattacks or data breaches.
3.When clearing your browser cache or disabling plug-ins, please pay attention to backing up important data to avoid losing personal information or causing other unnecessary losses.
4.When turning off your firewall or security software, take care to protect your computer from malware or viruses. It is recommended to temporarily turn off the firewall or security software only when necessary and re-enable it after use.
In short, the problem that Apple computers have a network but can't open web pages may involve many aspects, and they need to be troubled and dealt with one by one. During the process, please be cautious and follow the correct operating procedures and precautions to ensure the security of your computer and the smooth flow of the network.
