âReally bigâ change coming to an Apple icon A product the company has left virtually unchanged for more than a decade is due for a massive update in the coming months. Technology by Jack Gramenz 6th Apr 2021 3:54 PM An expected update to Apple's iMac range of all-in-one desktop computers could super-size the display to the size of a television. The current iMacs start with a 21.5-inch display and jump up to a larger 27-inch display, as they have since 2009. That was more than a decade and a completely different approach to Apple computers ago so it would make sense for the company to make an update.
