yeah mine is like that too. Its made to come off so it should be a little loose, just slide it off and put it back on and see if that helps at all.
It sounds like for whatever reason, the actual adapter is somewhat warped and that the accessory bits aren't connecting the way that they should be. I would ask for a replacement adapter just to be on the safe side, a little gap isn't an issue and it's definitely not a hazard, but something like this is a bit worrying.ive just checked the cord plug and it has the same issue. i think its the magsafe itself![]()
