Apple has released macOS 26.3, following last week's release candidate rollout. The update brings build number 25D125 and focuses primarily on under-the-hood improvements rather than major new features.

This point update includes references to unreleased Apple Silicon chips, specifically the M5 Max and M5 Ultra, which are expected to power the next MacBook Pro refresh. Notably, the M5 Pro chip was absent from the release candidate's internal code, supporting theories that the M5 Pro and M5 Max may share the same chip architecture.

The update is expected to arrive alongside Xcode 26.3, which introduces agentic coding capabilities through integration with tools like OpenAI's Codex and Anthropic's Code agent. These features aim to streamline the development process for app creators. While macOS 26.3 lacks headline-grabbing changes, Apple emphasizes the importance of installing updates for critical bug fixes and security improvements.
