    Hello CheshamChris,

     

     

    Due to the fact that your Magsafe adapter has a loose wire, it would be best to take your Magsafe adapter to an Apple Store to have it evaluated. It may even be eligible for free replacement.

     

    You should not use power adapters that have strain relief damage or that are missing insulation or rubber. Do not attempt to repair an adapter cable in this state.

     

     

    Whether or not your product is in or out of warranty, you can take your adapter to an Apple Authorized Service Provider or Apple Retail Store for evaluation and replacement if necessary. Pending the results of the evaluation, you may or may not be eligible for a replacement adapter free of charge. Signs of accidental damage would negate any coverage. Be sure to bring in the computer used with the adapter; it is required to process potential adapter replacements.
