Hey guys, so I have a charging cable from when I bought my MacBook Pro back in 2011 and have been using it since. The only problem is, like the lightening cables, the MagSafe charger disintegrates with frustrating reliability. Mine actually started going black and falling off in clumps. I have no idea why this happens, but I have a solution. ABS Solvent. Just apply it liberally to any exposed area and let it dry. Works like a bloody charm.
