When looking at the connections of your Apple OSX system, all network devices show FAILED instead of CONNECTED or NOT CONNECTED.
Basically there is a file corruption on the system.
Okay what we’ll need to do is go to Mac HD/Library/Preferences/system configuration and move the system configuration to your desktop and then restart your iMac.
It will reset your system configuration and hopefully when you restart the issue will be resolved if there is some sort of configuration error that is causing the issue.
We have tested this with one of our clients today and works 100%. Obviously you will need to renter WIFI passwords and if DHCP is running, it will just automatically reconnect to LAN or Wifi.
