Recently I had a problem with my mac, my wifi connection was working properly but my ethernet connection was not it was getting a self-assigned IP. After checking the obvious culprits (cable, router, switch) it turns out that the problem was elsewhere.
After searching the internet I realized that I wasn't the only one having this problem, and there are a lot of fixes such as :
- Deleting the "/Machintosh HD/Library/Preferences/com.apple.alf.plist" and rebooting
- Resetting the PRAM
- Recreating a network configuration
By chance I decided to try and disable IPv6 on the network interfaces like so :
networksetup -setv6off Wi-Fi networksetup -setv6off Ethernet
And after rebooting it worked !!
So there you go; I hope this works for you too!!
On a final note: Another thing I was about to try was uninstalling the virtual interfaces of my VMWARE but it didn't get to that
