Mine was an easier fix than the way I did it with Mavericks.

I was able to fix it using the guide below, but I had to continue through the steps and switch to the Clover bootloader.

Is your ethernet connection set at "en0" ?

I fixed this issue in a thread I started a few days ago:

"For those of you who can't login to Appstore, make sure your Ethernet built'in is set à en0 (you can see that in System Information, ioreg and Network utility). If not, then go to Network in System Preferences and delete all your devices, apply, then deleteLibrary/Preferences/SystemConfiguration/NetworkInterfaces.plist. Reboot, go to Network in System Preferences again and add your Ethernet connection FIRST. You're good to go!"

At first I couldn't find this file path, but now I'm seeing it. I'm thinking it's because of Clover. I don't remember seeing this file path when using Chimera, unless I'm mistaken.

Hi, i only have wifi connection because Yosemite does not take my ethernet card... so, can i do it the same way only with my usb wifi adapter?

Thank you

This fix worked great for me. Thanks again!
