It seems like Apple has finally put the 21.5-inch iMac out to pasture.
"Tech God" appears to be the first to have noticed that Apple quietly removed the product from its online store. 9to5Mac reports that, per unspecified "archive data," the sole remaining 21.5-inch iMac model was removed from the Apple Store Online sometime on Oct. 29.
This isn't much of a loss. 9to5Mac says Apple only sold one configuration option, and the company was charging $1,099 for an all-in-one that featured a 1080p display and a four-generation-old dual-core Intel processor, along with other dated components.
Apple has slowly culled Macs that feature Intel processors from its product lines since the M1 chip debuted in the Mac mini, MacBook Air, and MacBook Pro in late 2020. That chip made its way into a new 24-inch iMac in April; the 21.5-inch model's days have been numbered since.
The 27-inch iMac remains available, but that might change sooner than later. Apple is rumored to be planning the release of a new 27-inch iMac Pro with a mini-LED display, a design inspired by the 24-inch model, and the new M1 Pro and M1 Max chips for the first half of 2022.
If those rumors bear out, the only remaining Mac not to feature Apple's custom silicon will be the Mac Pro, and even that is expected to change before too long. By that point Apple will simply have to sell through its existing inventory to finalize its transition away from Intel processors.
