The Leak That Changed Everything
In what can only be described as a holiday gift for Apple enthusiasts, leaked kernel debug kit files from Apple engineers have revealed an iMac with the identifier J833c running on platform H17C, which is associated with the M5 Max chip, codenamed “Sotra C”. This isn’t just speculation or wishful thinking—it’s concrete evidence found in the same files that accurately predicted dozens of other Apple products.
The discovery, first reported by MacRumors, has sent shockwaves through the tech community. Screenshots and secondary confirmations have been circulating on Chinese platforms like Weibo and Bilibili, lending credibility to what many thought was impossible: Apple bringing back the iMac Pro.
A Nostalgic Return: Why the iMac Pro Matters
For those who remember, the original iMac Pro launched in 2017 as Apple’s answer to professional creative workflows. It was adored by many but ultimately appeared to be just a stopgap while Apple worked on the Mac Pro, and was discontinued in 2021 when the regular 27-inch iMac began outpacing it.
Since then, professionals have been left with a gap. The current 24-inch iMac with the M4 chip is beautiful and capable, but it’s designed primarily for home users and light creative work. Power users have been forced to choose between the Mac Studio (which requires a separate display), the MacBook Pro (which lacks the all-in-one convenience), or the eye-wateringly expensive Mac Pro.
An iMac Pro with the M5 Max would fill this void perfectly, offering desktop-class performance in the sleek, space-saving form factor that creative agencies and professionals have been craving.
What Makes the M5 Max Special?
Apple’s M5 chip family represents a significant leap forward in silicon design. The M5 offers unified memory bandwidth of 153GB/s, providing nearly a 30 percent increase over M4 and more than 2x over M1, with the unified memory architecture enabling the entire chip to access a large single pool of memory.
But the M5 Max takes this even further. As the “Max” designation suggests, this chip is built for demanding professional workloads:
Performance That Commands Respect
- Massive GPU Power: The M5 architecture features a next-generation GPU with Neural Accelerators in each core
- AI Performance Boost: Over 4x the peak GPU compute performance for AI compared to M4
- Memory Capacity: Up to 32GB of unified memory for running complex creative suites simultaneously
- Professional Workflows: Designed for 3D rendering, video editing, software development, and data analysis
The Perfect Balance
What makes the M5 Max particularly exciting for an iMac Pro is its ability to deliver pro-level performance while maintaining the efficiency Apple Silicon is known for. You get the raw power needed for intensive tasks without the thermal constraints or noise levels that plagued Intel-based machines.
Display Dreams: Mini-LED Now, OLED Later
While the M5 Max iMac Pro is expected to launch in 2026, display technology leaks suggest an even more exciting future ahead.
The 2026 Model: Mini-LED Brilliance
Apple’s display technology advances mini-LED backlighting to 2000 nits sustained HDR, compared to the current 500 nits, enabling professional-grade brightness and True Tone Pro adjustments. This represents a massive fourfold increase in brightness, putting the iMac Pro on par with the best professional displays.
Expected display features include:
- 32-inch 6K resolution – Matching the Studio Display 2 specifications
- 120Hz ProMotion – Smooth scrolling and responsive interactions
- Nano-texture glass option – Reducing glare by 60% for colour-critical work
- HDR support – True professional colour grading capabilities
The Future: OLED Revolution
Apple has submitted requests for OLED display proposals to Samsung and LG with a deadline for development set for next year, meaning the first OLED iMac will be released in 2027 at the earliest. This OLED version would likely feature:
- Even higher peak brightness levels
- Perfect black levels and infinite contrast
- Improved power efficiency
- Enhanced colour accuracy for professional workflows
The strategy is clear: launch the M5 Max iMac Pro in 2026 with cutting-edge mini-LED technology, then follow up with an OLED version (likely with M6 chips) in 2027 or 2028.
Design Evolution: Slim, Sleek, and Powerful
Gone are the days of thick, heavy all-in-ones. The iMac design refresh adopts a slimmer 11mm profile, achieved through liquid cooling that sustains 120W M5 Max performance without throttling.
This engineering feat means you get:
- Desktop Power in a Sleek Package: No compromises on performance despite the thin profile
- Thermal Stability: Advanced liquid cooling for sustained peak performance
- Whisper Quiet Operation: Efficient cooling means less fan noise during intensive tasks
- Studio Display-Inspired Aesthetics: Modern, premium design language
Connectivity for Professionals
One area where the current 24-inch iMac falls short is connectivity. The M5 Max iMac Pro addresses this head-on with:
- Four Thunderbolt 5 ports – Lightning-fast data transfer for external storage and displays
- HDMI 2.1 – Direct connection to additional displays or capture devices
- SDXC card slot – Essential for photographers and videographers
- Modular port design – Eliminating the dongle nightmare
This comprehensive port selection means professionals can finally connect all their peripherals without buying a separate hub.

The Reality Check: Will It Actually Launch?
Here’s the elephant in the room: MacRumors qualifies that this Mac is being used for testing purposes only and isn’t necessarily slated for release to the general public. The leaked files also reference devices known to be test-only units, like iPad minis running tvOS.
However, several factors suggest this is more than just an internal test device:
Strong Industry Support Bloomberg’s Mark Gurman believed that Apple was still working on a larger-screened iMac aimed at the professional market, a rumor supported by Apple analyst Ming-Chi Kuo. These industry insiders have track records of accuracy.
Market Demand Since 2021, professionals have been vocally asking for a high-end iMac. The gap in Apple’s lineup is real and significant.
Product Portfolio Logic Apple currently offers the Mac Studio and Mac Pro at the high end, but both require separate displays. An all-in-one professional option makes strategic sense.
Timing Aligns The M5 Max chips are expected in 2026, coinciding with when industry sources have predicted a pro iMac launch.
Pricing Expectations: Premium Performance Demands Premium Price
