Hi Everyone - I haven't been on here in awhile but I have a problem. My power cord to my MacBook Air split right about where the metal head snaps into the notebook magnetically, and now it's not working anymore. I was wondering if any of you know the answer to this. I still have that really thick power cord that plugs into the wall one one end and on the other end plugs into the brick which is attached to the cord that is broken. I am just looking for the that cord only - the one that has the magnetic head on one end to connect to the notebook and the brick on the other. I keep finding is the entire thing which is $79.
