Apple's upcoming iOS 26.3 release is stirring up excitement among tech enthusiasts, with a potential sneak peek at the company's future hardware plans. But what's hidden in this release might surprise even the most seasoned Apple fans.
The iOS 26.3 release candidate, released on February 4, 2026, includes references to two mysterious Apple chips, which could be the highly anticipated M5 Max and M5 Ultra. These chips have been the subject of speculation for quite some time, and their appearance in the iOS code is intriguing.
Here's where it gets even more intriguing: the release candidate mentions the T6051 chip, codenamed H17C, and the T6052 system-on-chip, known as H17D. Apple's naming conventions suggest that H17C is likely the M5 Max, following the pattern of previous 'Max' chips like the M1 Max (H13C) and M4 Max (H16C). And the H17D chip? Well, it might just be the M5 Ultra, as the 'D' in the naming scheme aligns with the M1 Ultra to M3 Ultra chips.
But wait, there's a twist! The iOS 26.3 RC is curiously missing any mention of the T6050 or H17S chip, which is expected to be the M5 Pro. Has Apple changed its naming system, or is there another explanation?
With the macOS 26.3 update expected to bring new MacBook Pro models with these chips in February or March 2026, the anticipation is building. And this is the part most people miss: the iOS release might just be the first public hint at Apple's next-generation hardware.
What do you think? Are these the M5 Max and M5 Ultra chips, or does Apple have something else up its sleeve? Share your thoughts in the comments below!
