Hey,

 

As noted before I have everything working in Yosemite on my Optiplex 760.  The only thing left is this error trying to log into the App Store.  I have done some research on this and have tried various scenarios to try and fix to no avail.

 

First my TP-link wireless adapter shows up as en0 as it should to be able to log in ok.  I have tried the following to fix

 

add EthernetBuiltIn as Yes to my com.apple.boot.plist

 

 

1. Go to HDD MAC 

2. Library/Preferences/SystemConfiguration

3. Delete all in folder SystemConfiguration

4. Go to System Preferences > Network 

5. Delete all card network ( in list ) 

6. Reboot > sign in appstore

 

neither worked.  I have tried to remove the wireless adapter and go with the built in ethernet connector on the 760 but after enabling the connection in the Bios clover will not boot at all.  I have enabled built in Ethernet via clover configurator and made sure the proper kext is installed.

 

So I am at an impasse.  Any suggestions to try would be greatly appreciated.

 

Cheers,  Howard
