MacOS 12.0.1

macOS 12.0.1 (build 21A559) is an update to macOS 12 (Monterey) that was released on October 25, 2021 by Apple Inc. Though early shipments of Apple M1 Pro and M1 Max-based MacBook Pros had macOS 12.0 pre-installed, security updates necessitated that version 12.0.1 become the first standalone release of Monterey to the general public, in a similar situation as macOS 11.0.1 for the first M1-based Macs nearly a year earlier.

Development
Xcode 13.1 is bundled with the macOS 12 software development kit (SDK).
