I want to get another power cord for my MacBook pro.
The original is a 85W MagSafe Power Adapter, A1290.
I'm looking at reconditioned
ones or clones
since they are considerably cheaper.
They have 2 conductor plugs. My original has 3 conductor. Is the ground necessary?
The clone does not list A1290 in the compatible model numbers. They are both 85W, though, so they are compatible?
