Herro. My mac charger used to work perfectly untill 2 days ago, now the charger just works whenever it feels like it, every few hours it might work and if it does work and i pull it out the put it back in it just stops working agian. Is it just charger PMS or is there something wrong with it.

It could be a shortage in the charger. Or it just may getting old. My school Mac charger was acting like that and a few days later it went out completely. I had to get a new one. You may be able to find out where the shortage is and fix it.

Oh okay thanks, if it goes completely out i will just buy a new charger, and it is pretty old anyway. What is a charger shortage? thanks.
