At least two new iMacs may be in the works, according to Gurman in the most recent issue of his Power On newsletter. According to Gurman, Apple is working on a new 24-inch iMac with a standard M3 processor in 2023, and it is also working on a high-end iMac.
A larger-screen iMac for professionals is still in the works, in my opinion, as is an upcoming iMac from Apple. My guess is that this will make use of the M3 chip in some form or another, either the M3 Pro or M3 Max. That would be in line with the MacBook Pro’s processors. Adding an Apple Studio Display to a Mac Studio or a Mac mini doesn’t seem to be enough for many professional users who need more screen space.
Apple discontinued the 27-inch Intel-based iMac in March 2022 and the iMac Pro in March 2021, leaving just the 24-inch iMac with the M1 CPU as the last extant iMac model. According to Gurman and other industry observers, Apple has already phased out the 27-inch iMac in favor of the Mac Studio and its accompanying Studio Display. However, Gurman and other industry observers believe that a higher-end iMac is still in the works.
Apple’s product roadmap does not include an M2 chip-equipped 24-inch iMac in Gurman’s forecast, which also includes M2 and Pro editions of the Mac mini, as well as new 14-inch and 16-inch MacBook Pro models, as well as an M2 Ultra and “M2 Extreme” chip-equipped tower Mac Pro. Gurman anticipates that the initial M3 series of Macs will contain an improved 24-inch iMac, as well as an all-new 15-inch MacBook Air and possibly a new 12-inch laptop that is “still in early development.”
Because of the use of M3 series CPUs, it’s possible that the next high-end iMac won’t be available until 2023, as Gurman previously predicted. M3 chips are planned to be created on TSMC’s 3nm technology, unlike M1 and M2 chips that are built on their 5nm processes. Improvements in performance and efficiency are envisaged as a result of the new manufacturing method.
