macOS Tahoe 26.3.1 update will "upgrade" your M5's CPU to new "super" cores

  • Earlier this week, Apple released macOS Tahoe 26.3.1, which formally renamed M5 performance cores to `Super` and updated their labels in the System Information app and Activity Monitor.
  • Apple announced the M5 Pro and M5 Max earlier this week, introducing a new mid-tier performance core while keeping efficiency cores unchanged.
  • MacOS 26.3.1 ships on new MacBook Neo, M5 MacBook Air, and MacBook Pro with M5 Pro and M5 Max, adding support for Studio Display and Studio Display XDR.
  • Because the renaming applies retroactively to the preexisting M5 MacBook Pro, Apple and observers note macOS 26.3.1 is a cosmetic relabeling, so users should not expect different behavior.
  • On Feb. 26, Apple rolled out related OS updates including visionOS 26.3.1 alongside macOS 26.3.1, listing the update on Apple's security release site but providing limited explanatory notes.
