Released on Sunday, the support document shows the part numbers and images of the MagSafe adapters, AC plugs (the "duck head" adapter) and power cords.
Until the latest "Late 2007" model, MacBooks used the same 60-Watt MagSafe adapter. Saving a bit of confusion, all of Apple's notebooks, including the MacBook Air, use the same power cord and duck head plug.
However, the document isn't really clear about the 85-Watt adapter used on the MacBook Pro. The first versions used the 4259 adapter. The Core 2 Duo models went with the 4339 adapter.
The low-power MacBook Air uses a small 45-Watt adapter.
It's only for U.S. notebooks, Apple said.
