Apple is working on an updated 24-inch iMac and an all-new “Pro” iMac ahead of an approximate launch time frame at the end of this year, according to key reports from over the past year.
In mid-2022, Bloomberg‘s Mark Gurman suggested that Apple is working on at least two iMac models, likely using the “M3” series of chips. He said that Apple will likely launch an updated 24-inch iMac featuring the standard M3 chip in 2023 and is continuing work on a high-end iMac model:
I also still believe that Apple is working on a larger-screened iMac aimed at the professional market. I’d imagine this will use a variation of the M3 chip, likely an M3 Pro and M3 Max. That would match the chips inside of the MacBook Pro. I don’t think the combination of a Mac Studio or Mac mini plus an Apple Studio Display cuts it for many pro users who want more screen real estate.
Apple discontinued the iMac Pro in March 2021 and it discontinued the 27-inch Intel-based version of the iMac in March 2022, leaving the 24-inch iMac with the M1 chip as the only remaining iMac model. For now, Apple has effectively replaced the 27-inch iMac with the Mac Studio and its matching Studio Display.
