Unless your model is incredibly old, it probably has built-in dual voltage. This means that your MacBook will function on the United States' 110-volt system, Europe's 220-volt system, and Australia's system, which can reach up to 240 volts..
Then, can I plug my MacBook into 220v?
Yes all you need is a plug adapter to convert to the correct plug style. You can either use the world travel set from Apple or by just a plug adapter that the MagSafe will plug into. I concur with the previous poster, it works just fine on 220v as long as you have a converter plug for the electric outlet.
Also, is the MacBook Pro Dual Voltage? The MacBook Pro runs on every voltage available in the world, specifically it runs on 100 to 240 volts at 50 or 60 hertz as well as 15 or so volts (DC) from its battery. A plug adaptor is the only thing you will need. It's not just "dual voltage", but universal voltage within the specifications of the power adapter.
