When you’re among the many rising variety of customers hoping to see up to date MacBook Professional variations with new M5 chips sooner relatively than later, as we speak’s macOS 26.3 RC brings some nice information. Listed here are the main points.
M5 Max and M5 Extremely referenced
As reported by MacRumors, as we speak’s macOS 26.3 Launch Candidate construct contains references to what are very possible two new M5 chips for upcoming MacBook Professional updates.
Extra particularly, macOS 26.3 RC contains inside references to 2 new SoC IDs, T6051 and T6052, that are tagged with platform codes H17C and H17D.
To make sense of those codes, listed below are the SoC IDs and platform codes Apple has used thus far for all different M-series Apple Silicon chips:
| Chip | SoC ID | Platform code |
|---|---|---|
| M1 | T8103 | H13G |
| M1 Professional | T6000 | H13J or H13S |
| M1 Max | T6001 | H13J or H13C |
| M1 Extremely | T6002 | H13J or H13D |
| M2 | T8112 | H14G |
| M2 Professional | T6020 | H14S |
| M2 Max | T6021 | H14C |
| M2 Extremely | T6022 | H14D |
| M3 | T8122 | H15G |
| M3 Professional | T6030 | H15S |
| M3 Max | T6031 or T6034 | H15C or H15M |
| M3 Extremely | T6032 | H15D |
| M4 | T8132 | H16G |
| M4 Professional | T6040 | H16S |
| M4 Max | T6041 | H16C |
| M5 | T8142 | H17G |
Based mostly on this customary, it’s possible that the T6051/H17C IDs check with the upcoming M5 Max chip, whereas the T6052/H17D IDs check with the M5 Extremely.
Curiously, there appear to be no references to the M5 Professional chip (which ought to carry the T6050/H17S identifiers) but, though, not less than in concept, the RC ought to be the very same construct that can roll out publicly when the discharge candidate turns into the ultimate launch.
What meaning for the discharge timeline of the subsequent MacBook Execs, we’ll possible discover out sooner relatively than later, as Bloomberg just lately reported that the brand new fashions are “slated for the macOS 26.3 software program cycle”.
