Apple Mac update changes how MacBooks charge to make them live longer

Apple has rolled out a new Mac update that changes the way its computers charge. The company says the new technology will allow those batteries – and therefore the computers they are in – to last longer. As they do, the amount of charge they can hold drops, until they eventually become so short their life is over. The new feature aims to slow down the rate at which that ageing process happens. It does so by watching how hot it gets and when it tends to be charged.
