Apple is testing a powerful new iMac that runs on the M5 Max chip. You see this detail inside leaked internal software used by Apple engineers. The data points to a high-end model aimed at professional users, not the current consumer iMac.
The evidence comes from Apple’s kernel debug kit files. These files list unreleased hardware by internal identifiers and platform names. They often link those identifiers to specific chip codenames and future marketing names. Over the past week, screenshots and summaries of the same data have also circulated in Chinese tech forums.
Internal Files Reveal
The software mentions an iMac with the identifier J833c. It runs on a platform called H17C. Apple internally links H17C to the codename “Sotra C,” which matches the M5 Max chip. That combination strongly suggests Apple is actively testing an iMac powered by M5 Max.
You should know that these debug kits also list unusual test devices. Some examples include iPad minis running tvOS and MacBooks powered by iPhone chips. Because of that, not every listed device reaches customers. Still, the timing matters. Apple plans to introduce more M5 chips next year, and talk of a Pro-level iMac has never fully stopped.
Other Macs Listed in the Leak
The same files outline a broad roadmap for future Macs. Here is what shows up:
- 14-inch and 16-inch MacBook Pro models with M5 Pro and M5 Max
- A 14-inch MacBook Pro with the M6 chip
- 14-inch and 16-inch MacBook Pro models with M6 Pro and M6 Max
- 13-inch and 15-inch MacBook Air models with the M5 chip
- Mac mini models with M5 and M5 Pro
- Mac Studio models with M5 Max and M5 Ultra
- A MacBook powered by the A18 Pro chip, likely a new low-cost model
If Apple ships this iMac, you get a true desktop-class Mac again. The M5 Max points to strong CPU and GPU performance, higher memory limits, and better support for demanding workflows. For now, Apple stays quiet. Still, internal testing shows the company is not done with the idea of a professional iMac.
