Moving an iMac from the USA to Australia
I recently moved from the USA to Australia. I went to an Apple store to buy an Australian power cord. They did not have any but recommended that I buy a kettle cord on eBay. I did but heard a faint crackly or staticky sound when I started to plug it into the computer. I got scared of frying my computer and did not finish plugging it in. My USA plug was for 125 Volts. My Australian plug is for 250 Volts.
while I am grateful for all knowledgeable answers, I would prefer if an Apple expert answered this question but how can I know for sure that I won’t fry my computer? I once fried a hair straightener here while using an adapter and want to keep that from happening to my computer.
I am attaching a photo for illustration purposes.
