At times, Mac assigns itself an IP address, which prevents the Internet from working. Even if the computer is connected to Wi-Fi network, you won't be able to use the Internet. To fix Internet not working error due to the self-assigned IP address on Mac, you will have to wipe out some files.
Don't worry the process isn't quite lengthy and works reliably. The other day, I encountered this same issue and was able to troubleshoot it by following this trick.
How to Fix Self-Assigned IP Address Issue on Mac running macOS High Sierra or Later
Step #1. Launch finder on your Mac.
Step #2. Now, click on Macintosh HD.
Step #3. Now, you need to click on the Library folder and head over to Preferences.
Step #4. Next, click on the System Configuration folder.
Step #5. Next up, you have to move the following files in the trash.
Note: In case these above files are there, delete the similar files that are available.
Step #6. Finally, restart your Mac.
Note: If Macintosh HD is not available in the Finder sidebar, click on the Finder menu → Preferences → click on the “Sidebar” tab → Under “Show these items in the sidebar” click on “Hard disks.”
After your computer has restarted, self-assigned IP address issue will be gone, and you will be able to use the Internet without any problem.
