MacBook owners have been dealing with broken adapter wires for quite some time and Apple is now redesigning them to prevent the wires from breaking. They have pulled the adapters from their online store and have halted shipments to resellers while they ready the new adapters with better wires. Word on the street is the new adapters should be shipping in a few weeks so don’t break your existing adapter wire now, wait for the new ones to become available. I am a bit surprised that it has taken Apple so long to admit a problem and update the adapters, I remember months ago talking to Matt Miller who had to have his adapter replaced for this very same problem. Oh well, better late than never.
