Software leaks point to the first Apple Silicon “iMac Pro,” among other devices

Apple doesn’t like to talk about its upcoming products before it’s ready, but sometimes the company’s software does the talking for it. So far this week we’ve had a couple of software-related leaks that have outed products Apple is currently testing—one a pre-release build of iOS 26, and the other some leaked files from a kernel debug kit (both via MacRumors).

Most of the new devices referenced in these leaks are straightforward updates to products that already exist: a new Apple TV, a HomePod mini 2, new AirTags and AirPods, an M4 iPad Air, a 12th-generation iPad to replace the current A16 version, next-generation iPhones (including the 17e, 18, and the rumored foldable model), a new Studio Display model, some new smart home products we’ve already heard about elsewhere, and M5 updates for the MacBook Air, Mac mini, Mac Studio, and the other MacBook Pros. There’s also yet another reference to the lower-cost MacBook that Apple is apparently planning to replace the M1 MacBook Air it still sells via Walmart for $599.

For power users, though, the most interesting revelation might be that Apple is working on a higher-end Apple Silicon iMac powered by an M5 Max chip. The kernel debug kit references an iMac with the internal identifier J833c, based on a platform identified as H17C—and H17C is apparently based on the M5 Max, rather than a lower-end M5 chip. (For those who don’t have Apple’s branding memorized, “Max” is associated with Apple’s second-fastest chips; the M5 Max would be faster than the M5 or M5 Pro, but slower than the rumored M5 Ultra.)

This device could be the long-awaited, occasionally-rumored-but-never-launched replacement to Apple’s 27-inch iMac, which was discontinued in 2022 with no direct replacement. An M5 Max chip would also make this machine the closest thing we’ve seen to a direct replacement for the iMac Pro, a 27-inch iMac variant that was launched in late 2017 but likewise discontinued without an update or replacement.

The current M4 Max chip includes 14 or 16 CPU cores, 32 or 40 GPU cores, and between 36GB and 128GB of unified memory, specs we’d expect an M5 Max to match or beat. And because the Max chips already fit into the 14- and 16-inch MacBook Pros, it should be no problem to fit one into an all-in-one desktop PC.
