The 4K, 21.5-inch machine now comes with the option of a six-core, eighth-generation Intel Core i7 processor with Turbo Boost speeds up to 4.6 gigahertz. The non-Retina, 21.5-inch Mac will stay the same. The 21.5-inch iMac, the smaller desktop, previously came in two models: one without a Retina display and starting at $1,099, and another model with a 4K Retina display and a $1,299 starting price. But Apple is still carefully differentiating between a desktop that will appeal to families and small businesses, and the kind of iMac iPro that creative professionals will pay top dollar for. The iMac updates are largely focused on processing power, which nudge the machine closer to the performance levels of what you might consider a “pro” computer. Apple has just refreshed its line of iMac all-in-one desktop computers, making another understated announcement in what appears to be a week of spring hardware updates for the company.
