Hold onto your hats, Apple fans, because the latest iOS update just dropped a bombshell: hidden within the code of iOS 26.3's release candidate are references to not one, but two brand new, unannounced Apple chips. Could these be the highly anticipated M5 Max and M5 Ultra?
Here's the scoop: just a week after releasing the third developer beta, Apple quietly rolled out the iOS 26.3 release candidate. While the update itself seems feature-light, eagle-eyed developers discovered something far more intriguing – code snippets hinting at upcoming Apple silicon. And this is the part most people miss: these aren't just any chips; they're likely the next generation of Apple's powerhouse M-series processors.
Given the close relationship between iOS and macOS updates, it's no surprise that the M5 Max makes an appearance. AppleInsider previously reported that macOS 26.3 is expected to launch alongside new MacBook Pro models, making the M5 Max a strong contender for the upgrade. But here's where it gets controversial: the code also hints at an M5 Ultra, potentially destined for a refreshed Mac Studio. This raises questions about Apple's product roadmap and whether we'll see a significant performance leap in their professional-grade machines.
Digging deeper, the iOS 26.3 code reveals specific chip identifiers: T6051 (H17C) and T6052 (H17D). Based on Apple's naming conventions, H17C aligns with the 'Max' designation, as seen in previous generations like the M1 Max (H13C) and M4 Max (H16C). Similarly, H17D follows the pattern established by the M1 Ultra through M3 Ultra, strongly suggesting an M5 Ultra variant.
Interestingly, there's no mention of the T6050 (H17S), which was expected to be the M5 Pro. This omission could indicate a shift in Apple's internal naming strategy for the M5 family, or perhaps the M5 Pro is simply not part of this initial rollout. Either way, it's a fascinating development that leaves us with more questions than answers.
One thing is certain: new MacBook Pro models equipped with these cutting-edge chips are expected to arrive alongside macOS 26.3 in February or March 2026. But what do these new chips mean for performance? Will the M5 Ultra truly be a game-changer for creative professionals? And what about the missing M5 Pro – is it delayed, or something else entirely? These are the questions that have the Apple community buzzing. What's your take? Do you think the M5 Ultra will live up to the hype, or is Apple playing it too safe with their silicon strategy?
