how do i use an American Macbook pro in ireland?

The magsafe is compatible with all voltage/frequency combinations worldwide, you will need an adaptor to make the plug fit in the wall socket, that is all you need.

A simple $3 plug adapter is all you need. Your AC adapter will handle the rest.

The power adapter ? Just as everyone has said, that just works with a plug adapter or replacement plug. No step-down transformer needed.

If you are going to buy a new one, buy the one with the higher wattage (85 Watt instead of just 60 Watt). It will not get as hot running your MacBook, and will last longer. Apple says using the one with the higher wattage has NO ADVERSE IMPACT on any part of your MacBook, and they tend to cost almost the same.

The difference between the US model and the Irish model will be the detachable plug and the detachable AC mains cord, which will use different plugs. In Ireland, that may mean "NO plug, do it yourself", i am not sure.

Remember that when you coil the DC part of the cord (to the computer) you should leave a little slack on the first winding so as not to pull the cord out from the electronics.

Thanks for the almost instant answers

so if i buy an irish magsafe power adaptor for an american macbook pro it will work fine?

does the sockets in american walls and irish walls in normal households not differ? say my irish socket could give too much power and fry it or will the magsafe handle this?

You do not need another Magsafe (unless you want a spare) the one you have will work, just get a plug adaptor so you may plug it into the wall, that's about $3.

Magsafes will accept 90v to 240v, Ireland is 220-240v
