Apple has released a new Mac Mini – just half the size of its predecessor, already by far its smallest computer.

The new Mac is just five by five inches, Apple said. And it has the company’s recently released M4 chip, as well as the newly announced M4 Pro.

John Ternus, Apple’s hardware boss, said the computer “delivers gigantic performance in an unbelievably small design thanks to the power efficiency of Apple silicon and an innovative new thermal architecture”.

The new Mac Mini is also Apple’s first entirely carbon neutral computer, the company said. That had required an 80 per cent reduction in the emissions across not only its manufacture but also shipping and use by customers.
