    True ONLY for the Retina models in the 15" series. Non-Retinal "Classic" MPB 15" use the older type MagSafe.

    The adapter is only required for the 2012 Macbook Air and the 2012 Retina Macbook Pro. If you have one of the non-retina Macbook Pros you don't need it (and it won't fit).

    If it's from a MacBook 13" or 13" Pro then it won't have enough power to charge when it's under load as they have a less powerful charger

    On my new 2012 Macbook Air with Magsafe 2, the magsafe 2 to magsafe 1 adapter seems to either charge or power but not at the same time. If the macbook air is on, I get a "not charging" error, but it is powered by ac power. If I power the macbook down, it will charge.

    Intended behavior or bad adapter?

    Interesting. I hope that is NOT the intended behavior. I purchased a couple of the adapters for my extra 85W L shaped plugs and i will be extremely disappointed if that is the case.

    I'm using the magsafe that came with my 2010 MBP on my new 2012 MBP. Only the Air and rMBP have the new Magsafe 2. With the adapter, you can still use the old ones.

    The converter I had was defective, and they swapped it for a new one that works fine -- powers and charges at the same time. The apple care tech who told me otherwise wasn't too sharp, apparently.
