iOS Beta Uncovers M5 Max and M5 Ultra SoCs; M5 Pro Missing

Key Takeaways

1. Apple is expected to release the M5 Pro and M5 Max MacBook Pros soon, alongside the existing M5 model priced at $1,875.
2. New unreleased Apple M-series SoCs, T6051 and T6052, were found in the latest iOS 26.3 beta.
3. The “C” and “D” designations in the SoCs likely indicate the M5 Max and M5 Ultra models, with no current mention of an M5 Pro variant.
4. The absence of an M5 Pro could suggest a possible upcoming introduction or that an updated Mac Studio may launch sooner.
5. There are concerns about power management with high-end SoCs, as MacBooks typically struggle with the demands of an Ultra SoC without sacrificing battery life.

Apple is likely to release the M5 Pro and M5 Max MacBook Pros very soon, adding to the existing M5 MacBook Pro, which is currently priced at $1,875 on Amazon. Numerous rumors and insider information suggest that the launch of these new premium MacBooks is around the corner, with a recent leak indicating some intriguing details about the System on Chips (SoCs).

New SoCs Spotted

It’s not unusual for unreleased SoCs to appear in operating system beta versions, and this appears to have happened once again. Developer Nicolás Alvarez found mentions of two unreleased Apple M-series SoCs, known as T6051 and T6052, in the latest iOS 26.3 beta. The platform names associated with these chips are H17C and H17D.

Naming Conventions

As noted by MacRumors, the “C” and “D” designations likely correspond to the M5 Max and M5 Ultra models, based on Apple’s past naming patterns. This is curious because there seems to be no reference to a Pro version at all.

With the high-end MacBook Pros seemingly only days away from launch, it’s puzzling that there has been no mention of an M5 Pro variant. It’s certainly possible that Apple might introduce the M5 Pro identifier soon, but there is also a chance that the updated Mac Studio could launch sooner than anticipated.

Power Management Concerns

MacRumors also mentions that Apple might include the M5 Max and M5 Ultra SoCs in the high-end MacBook Pros. However, this seems unlikely because MacBooks generally struggle to handle the power and thermal demands of an Ultra SoC without compromising on battery life and overall efficiency.
