If you’re experiencing issues with your Mac where you can only connect to the internet in Safe Mode, it’s a clear indication that there’s a problem with your system that needs immediate attention. This issue can be frustrating, especially when you rely on your Mac for work, communication, or entertainment. In this article, we’ll delve into the possible causes of this problem and provide you with step-by-step solutions to get your Mac connected to the internet in normal mode.
Understanding Safe Mode on Mac
Before we dive into the troubleshooting process, it’s essential to understand what Safe Mode is and how it works on a Mac. Safe Mode, also known as Safe Boot, is a diagnostic mode that starts your Mac with the minimum number of drivers and software. This mode is designed to help you troubleshoot issues with your system by disabling non-essential services and loading only the necessary components. When you start your Mac in Safe Mode, it performs a directory check of your startup disk, loads only essential kernel extensions, and disables all fonts, except those required by the system.
Causes of Internet Connectivity Issues in Normal Mode
There are several reasons why you might be able to connect to the internet only in Safe Mode on your Mac. Some of the most common causes include:
- Conflicting kernel extensions: Kernel extensions are system components that extend the functionality of your Mac’s operating system. Sometimes, these extensions can conflict with each other or with the system, causing connectivity issues.
- Software conflicts: Third-party software can sometimes interfere with your Mac’s ability to connect to the internet. This could be due to a bug in the software or a compatibility issue with other system components.
- Network configuration issues: Problems with your network settings or configuration can prevent your Mac from connecting to the internet in normal mode.
- Malware or viruses: In some cases, malware or viruses can affect your Mac’s connectivity, although this is less common on macOS devices due to their built-in security features.
Troubleshooting Steps
To resolve the issue of being able to connect to the internet only in Safe Mode, follow these troubleshooting steps:
Start by restarting your Mac in Safe Mode. If you can connect to the internet in Safe Mode, it indicates that the issue is likely related to a software or configuration problem rather than a hardware issue. Next, try resetting your System Management Controller (SMC) and your Network settings. The SMC is responsible for managing various system functions, including network connectivity. Resetting it can sometimes resolve connectivity issues.
Resetting SMC and Network Settings
To reset the SMC on your Mac, follow these steps:
– Shut down your Mac.
– Locate the following keys: Power button, Command (⌘) + Option (⌥) + Shift (⇧) + Power.
– Press and hold all these keys while you press the Power button.
– Hold them for 10 seconds, then release.
– Press the Power button again to turn on your Mac.
To reset your network settings:
– Go to System Preferences > Network.
– Select your network connection (Wi-Fi, Ethernet, etc.) from the left side.
– Click the “Advanced” button.
– Go to the “TCP/IP” tab and click the “Renew DHCP Lease” button.
– Then, go to the “Wi-Fi” tab (if you’re using Wi-Fi) and click “Advanced” again.
– Select the “TCP/IP” tab and click “OK.”
Advanced Troubleshooting and Solutions
If the basic troubleshooting steps don’t resolve the issue, it’s time to move on to more advanced solutions.
Disabling Login Items and Kernel Extensions
Sometimes, login items or kernel extensions can cause conflicts that lead to internet connectivity issues. To disable them:
– Go to System Preferences > Users & Groups.
– Select your user account and click “Login Items.”
– Look for any items that you don’t recognize or that might be causing issues and click the “-” button to remove them.
– To disable kernel extensions, you’ll need to use the Terminal app. Open Terminal and type kextstat | grep -v com.apple to list all non-Apple kernel extensions. Look for any that might be problematic and use the kextunload command to unload them.
Reinstalling Network Drivers and Software Updates
Outdated or corrupted network drivers can also cause connectivity issues. Ensure your Mac is updated with the latest software and drivers. Go to System Preferences > Software Update to check for any available updates. Additionally, consider reinstalling your network drivers. This process can vary depending on your specific network hardware, so you may need to consult the manufacturer’s support website for instructions.
Using Terminal Commands for Advanced Network Troubleshooting
The Terminal app on your Mac provides powerful commands for troubleshooting network issues. For example, you can use the ping command to test your internet connection, nslookup to troubleshoot DNS issues, and ifconfig to configure your network interfaces. These commands can help you identify where the problem lies and potentially fix it.
Conclusion and Final Steps
Being able to connect to the internet only in Safe Mode on your Mac indicates a software or configuration issue that needs to be addressed. By following the troubleshooting steps outlined in this article, you should be able to identify and resolve the problem. Remember to start with basic troubleshooting steps such as resetting your SMC and network settings, and then move on to more advanced solutions like disabling login items and kernel extensions, and reinstalling network drivers. If after trying all these steps you’re still experiencing issues, it may be worth considering a clean installation of macOS or seeking help from an Apple Support professional.
In the process of troubleshooting, it’s crucial to be patient and methodical, as resolving complex issues can take time.
