Apple Reported to Ready M5 Pro and M5 Max MacBook Pros for macOS 26.3 Window

Dwindling inventory plus warehouse staging suggest an unannounced launch is close.

Overview

  • Bloomberg’s Mark Gurman says the new high‑end MacBook Pros are planned for the macOS 26.3 release cycle.
  • macOS 26.3 remains in beta with a public release expected in February, pointing to a February–March hardware window.
  • Apple’s online store shows shrinking stock and delivery dates slipping into late February and March for current 14‑ and 16‑inch models.
  • Gurman reports finished units are already staged in global warehouses, with some reports citing internal identifiers J714 and J716.
  • Coverage characterizes the update as a chipset swap to M5 Pro and M5 Max with no major design changes, with larger redesigns expected later with M6.
