All Apple hardware is multi-voltage and will work anywhere in the world. As Suzant says, you just need to change the plug.
The Mac mini is a great little machine. Ours is plugged into our main TV so we can watch the iPlayer etc on a big screen.
I don't have a mini mac so I wouldn't know but I bought my mac laptop from the states. The power cable works fine here in Dubai since the adapter has dual voltage, but the only thing is, I use one of those extension plugs because it doesn't fit directly into the electric sockets here. You can find the voltage information under electrical and operating requirements" http://www.apple.com/macmini/specs.html
Heading to the US now and thinking of getting a Mini Mac. Does anyone have one ? Worth it?
Also will the power cable be okay to use in Dubai?
Thanks Ladies!
