Rumors suggest that Apple could be working working on a redesigned version of the larger-screened iMac that could potentially bring back the "iMac Pro" name to differentiate it from the smaller-screened 24-inch iMac.
In March 2022, Apple discontinued the 27-inch Intel-based version of the iMac, leaving just the 24-inch iMac, but that doesn't mean a new larger-screened iMac has been scrapped. Some rumors suggest that it is still in development and could launch in 2025, but not all sources are in agreement about the future of the iMac. For now, Apple has replaced the 27-inch iMac with the Mac Studio and its matching Studio Display, and the 24-inch model is the only iMac available.
Apple has confirmed that it has no plans to release another 27-inch iMac, but that does not rule out a model with a larger display.
Design and Screen Size
A refreshed larger-screened iMac could be similar in design to the 24-inch iMac, the Pro Display XDR, and the Studio Display. It's said to feature black bezels, and if it does indeed look similar to the Pro Display XDR, bezel size could be much slimmer and it could perhaps have less of a bottom chin.
According to Apple analyst Ming-Chi Kuo, the iMac will have a 32-inch display, which would put it at the size of the Pro Display XDR.
Like the 24-inch iMac, a future iMac Pro could be available in multiple color options. A 2021 report from DigiTimes suggested that Apple plans to sell the new iMac in various colors, though there are no specific details on which colors Apple will use and the rumor is now outdated.
Like the 14- and 16-inch MacBook Pro models, the next-generation iMac is expected to adopt a mini-LED display for brighter colors, deeper blacks, and improved HDR, and it will feature ProMotion display technology, allowing for up to a 120Hz refresh rate.
A refresh rate at 120Hz will allow for smoother gameplay and scrolling through various apps like Safari, plus it will improve general animations throughout macOS. Apple analyst Ming-Chi Kuo has said that Apple is working on a mini-LED iMac that's 32 inches in size, while Bloomberg's Mark Gurman has said that the iMac Pro will have a display that's over 30 inches.
Apple has apparently tested Face ID for the iMac Pro, but it is not a confirmed feature and it's not clear whether Face ID will make it into the release version of the machine.
The iMac is expected to offer a similar port configuration to the MacBook Pro, with Apple including USB-C/Thunderbolt ports, an SD card slot, and an HDMI port. Apple could also include an Ethernet port built into the power adapter as it has for the 24-inch iMac.
M3 Pro/Max Chips
Bloomberg's Mark Gurman believes a larger, more powerful iMac could feature M3 Pro and M3 Max chips, which debuted in the 14-inch and 16-inch MacBook Pro in late 2023, though rumors suggest a larger-screen iMac won't be coming until 2025 so it could adopt M4 Pro and M4 Max chips if those are ready in time.
Apple is reportedly calling the iMac the "iMac Pro" internally, and that could turn out to be its launch name as well, which would be in line with the MacBook Pro and iPad Pro.
An "iMac Pro" name differentiates the larger iMac from the 24-inch model, and makes it clear that it uses the same "Pro" chips as the MacBook Pro, but it is not clear if an "iMac Pro" fits into the Mac lineup alongside the more powerful Mac Studio.
Rumors suggest that a larger-screened iMac that could be positioned as an iMac Pro will launch in 2025. In June 2023, Bloomberg's Mark Gurman said that the iMac was a year or two away from launching as work on the device was still in the early stages.
M3 24-inch iMac
An M3 24-inch iMac was announced at Apple's "Scary Fast" event on October 30, 2023, but other than the new chip there were few changes compared to the M1 model from 2021 and Apple gave no indication about the potential for a larger model.
