Problems logging in.....

this still isn't working for me. I've tried all the network interface fixes. got nothing.

Me too, I’m not even using my Mac any more… I really wanted to upgrade to Lion. It’s just too expensive to fix my LAN port on my Mac! I am really disappointed that they can validate my MAC on my WIFI only.

I broke down and purchased the Apple Ethernet dongle for the MacBook Air because my ethernet port was also broken.... AppStore works like a charm now.

Thats great news, thanks! I'll go and do the same 😉

sarcasm ...

really, so when these amazingly put together hardware machines fail, you have no issues about spending even more money on hardware to fix the problem that should be fixed by Apple?

The only thing that helped me was a fresh install, updating straight from the install to the latest version, then buying the upgrade to Lion.

It did not work for me. I got hold of a Mac USB Ethernet adapter, but can’t get the device to register as en0.

hey WIFIGURU how do i find those files? could you give me a step by step on how to do what your saying? sorry, computer illiterate

thanks so much. After several weeks of trying to get this sorted (and I suspect trying out absolutely every other solutions suggested on the web!), I am now all sorted after following your instructions. I am extremely grateful to you for taking the time to post this.
