New M5 Chips Spotted in iOS 26.3 Beta (2026)

Get ready for a thrilling tech adventure! We've spotted something exciting in the iOS 26.3 beta, and it's got us all buzzing. Apple's next-gen M5 chips are making a surprise appearance!

But here's where it gets controversial... or at least, a little confusing. iOS 26.3 RC has references to two unreleased chips, T6051 and T6052, with platform names H17C and H17D. Now, if we follow Apple's usual numbering system, that suggests an M5 Max and an M5 Ultra chip. But where's the M5 Pro? It's nowhere to be found in the code.

This has sparked some interesting theories. Are we looking at an M5 Pro chip that's not yet added to the iOS 26.3 code? Or is Apple changing up its numbering game? Perhaps they're planning for M5 Max and M5 Ultra MacBook Pro models. Here's a quick breakdown:

  • Chip 1: T6051, H17C - Presumably the M5 Max.
  • Chip 2: T6052, H17D - Likely the M5 Ultra.
  • Missing: T6050, H17S - The expected identifier for the M5 Pro, but it's nowhere to be seen.

Apple has been consistent with its 'C' lettering for Max chips, like the M1 Max, M2 Max, and so on. Ultra chips have always been 'D' lettering, like the M1 Ultra and M2 Ultra. So, why are we only seeing signs of an M5 Max and M5 Ultra? Well, rumors suggest that new MacBook Pro models with these higher-end M5 chips are on the horizon. And there's talk of a Mac Studio in the M5 family, which would use an M5 Ultra chip.

But here's the part most people miss: we haven't heard any solid rumors about an upcoming launch for the Mac Studio. So, is it just a red herring? Or is Apple keeping us all on our toes with a surprise launch?

This is where it gets really interesting. What do you think? Are we looking at a major shift in Apple's chip naming convention, or is this just a clever way to keep us guessing? Let us know your thoughts in the comments! We'd love to hear your theories and predictions.
