Get ready to be blown away—Apple’s latest iOS 26.3 release candidate might just have spilled the beans on two brand-new chips: the M5 Max and M5 Ultra. But here's where it gets controversial: Could this be a deliberate leak, or is Apple simply testing the waters for its next big hardware reveal? Let’s dive in.
On Wednesday, February 4, 2026, Apple rolled out the iOS 26.3 release candidate, just a week after the third developer beta. While the update doesn’t seem to pack any flashy new features, it’s what’s hidden in the code that has tech enthusiasts buzzing. Buried within the software are references to two unreleased Apple chips, potentially the M5 Max and M5 Ultra. And this is the part most people miss: These chips could be the powerhouse behind upcoming MacBook Pro and Mac Studio upgrades, slated for early 2026.
Here’s the breakdown: The iOS 26.3 RC build mentions the T6051 chip (aka H17C) and the T6052 chip (aka H17D). Based on Apple’s naming conventions, the H17C is likely the M5 Max, following the pattern set by previous Max chips like the M1 Max (H13C) and M4 Max (H16C). Meanwhile, the H17D could be the M5 Ultra, as Apple has consistently used the letter 'D' for its Ultra chips, from the M1 Ultra to the M3 Ultra.
But here’s the twist: There’s no mention of the T6050 or H17S chip, which was expected to be the M5 Pro. Did Apple change its naming system for the M5 family, or is this chip simply not ready for prime time? It’s a question that has the tech community speculating.
What’s clear is that Apple is gearing up for a major hardware refresh. With macOS 26.3 tied to upcoming MacBook Pro models, and rumors pointing to a February or March 2026 release, it’s only a matter of time before these chips make their official debut. But here’s the real question: Will the M5 Max and M5 Ultra live up to the hype, or is Apple playing it safe with incremental upgrades? Let us know what you think in the comments—are you team M5 Max, M5 Ultra, or waiting for something even bigger?
