Do Mbps still have worldwide warranty? And are there any issues with the power brick if you buy in a country that has a different power to the country you live in?
The power brick is the same worldwide, just the duckhead is different.
All Macs have worldwide warranty.
I read somewhere that desktop Macs don't have worldwide coverage but MacBooks do. Has it changed?
The last I checked, AppleCare for all Macs are identical and are valid worldwide.
The power brick is the same worldwide, just the duckhead is different.
All Macs have worldwide warranty.
Where can I buy the duck head?
A person in the Apple Store told me they're not recommended as they are only for short term use such as on holiday.
Huh? Those are the exact same ones that ship with a computer depending on your location - the only difference is you get them all instead of just the one specific to where you bought it.
It is not as if the plastic is just going to start to disintegrate over time.
Then the store guy clearly didn't know what he was talking about.
Not surprising. You can also just get a universal adaptor and plug the US duckhead into it. Most are ugly but are more convent than carrying around a satchel of duckheads if moving among countries or you could get just an EU or just a UK one if that's the only place your headed.
