Apple will release a 21.5-inch iMac with a 4K display in October

Autumn is almost upon us, which means that Apple is about to release a whole bunch of new products. In addition to the new iPhones and the next-generation Apple TV that’ve been the subject of an endless stream of rumors these past few months, the company is also expected to release a new 21.5-inch iMac with a 4K display. Last month, some bits of code were discovered within the latest version of OS X which hinted at the release of such a device, and now 9to5Mac’s sources have confirmed that a 21.5-inch 4K iMac will be launching sometime this October. 

Code snippets in Mac OS X El Capitan hinted at a new 21.5-inch iMac with 4K display last month and now reports are coming in that the desktop will arrive in October. Mark Gurman’s sources over at 9to5 Mac say Apple will introduce the updated computer in October with November availability. That would make the higher resolution all-in-one Mac available in time for this year’s holiday season. Apple’s larger, 27-inch iMac got a big upgrade with a 5K display back last October, but the smaller desktop has since remained with a lower resolution screen. Based on OS X code, it’s a safe bet the 21.5-inch model will have a display resolution of 4096 x 2034 pixels. That works out to a pixel density of 218 pixels per inch. An open question is still the price of any such configuration. The larger 5k model starts at $1,999 while the current 21.5-inch iMac with standard screen begins at $1,099. I’d expect Apple to continue selling the lower resolution models — but with improved internals — at the same price. The new 4K iMac then would fit in nicely around $1,299.
