Apple’s MagSafe connector on the MacBookPro caught on fire. The problem is that the outer wiry layer which is made up of little pieces of really think wires becomes easily frayed over time, and it is this that burns out. I repaired my cable with stuff I found around the office, some scissors to strip the cable, and some masking tape to cover the gap in the segmented wiry stuff. It now works fine. I doubt it’s even insulation tape. I might get some later.”]
