You’ll be fine — the Macbook chargers are engineered to work internationally. Take a look at this post — it’s old, but the information is still correct. You’ll see how to double-check your charger if you want to be completely sure. As long as it lists 100-240v as the input range, you’re good to go.

Just curious, what did you end up going with? I’m having the same issue in choosing my next purchase. I want light and durable, but I also use my computer mainly for editing photos.

I have a lock on my backpack and I keep it in there when travelling. I rarely take it out to coffee shops but that’s just because we do most of our work at home or at the apartment. These days, though, Macs are everywhere. We’re in a small University town in Mexico and you can walk into any café and there’ll be at least two or three, so you don’t have to worry about sticking out so much.

We’ve been travelling with Macs for three years now and never had an issue with their security. However, we also have insurance for them and back them up daily (to hard drives and into the cloud) just in case the worst happens.
