Same connector form, different documented roles

USB-C: Front USB-C ports — Front USB data · Rear Thunderbolt 5 (USB-C) ports — Thunderbolt 5 / USB4 / DisplayPort

Do not transfer a capability from one location to another merely because the connector outline matches.

Front USB data

Front USB-C ports

Apple lists two front USB-C ports up to 10Gb/s on the M4 Max model; they are kept distinct from the rear Thunderbolt 5 group.

Thunderbolt 5 / USB4 / DisplayPort

Rear Thunderbolt 5 (USB-C) ports

Four rear USB-C-shaped ports are documented as Thunderbolt 5 with USB4 and DisplayPort support. Connector shape alone does not transfer those capabilities to another USB-C port.

Read before using the profile

  • The front USB-C pair must not be treated as Thunderbolt 5 just because the rear ports use the same USB-C connector shape.
  • Display counts, cable capability and negotiated link rates are outside this selected port inventory.
