Great news for MacBook Pro fans awaiting the new M5 chips! The recent macOS 26.3 Release Candidate (RC) hints at exciting updates.
According to MacRumors, this update has references to two new chips: the M5 Max and M5 Ultra, identified by unique codes T6051 and T6052. This suggests they are meant for future MacBook Pro models.
Let’s break down what we know about these chips. Apple has a history of naming their silicon with specific codes. For example, the original M1 chip, which debuted in 2020, had the SoC ID T8103. Each new version typically follows this structured naming. So, it’s reasonable to think T6051 corresponds to the M5 Max and T6052 to the M5 Ultra.
Interestingly, there’s still no sight of the M5 Pro chip, which raises a few eyebrows. You’d expect all variants to be announced by now, but it appears the Pro version might be on a different timeline.
Industry experts believe these enhancements signify Apple’s commitment to pushing boundaries in laptop performance. In fact, a survey conducted by Statista shows that MacBook sales have increased by 14% in the last year, underlining the brand’s growing popularity.
As for when we can expect these new models? Reports from Bloomberg suggest they will launch in tandem with the macOS 26.3 cycle, which is looming large on the calendar.
In summary, the arrival of the M5 Max and M5 Ultra chips is set to elevate the MacBook Pro line-up once again. With the increased sales and buzz around Apple’s innovation, the laptop market is undoubtedly heating up.
