Apple research team recently released the container project. It is an open-source command-line tool written in Swift. It creates and runs Linux containers as lightweight virtual machines on a Mac. The project ships under the Apache 2.0 license and targets Apple silicon.
Containers are how you ship reproducible environments from a laptop to a datacenter. Apple now offers a native path that avoids a single always-on Linux VM.
What is Apple’s container ?
container is a CLI tool that can be used to build images, run containers, and move images to and from registries. It consumes and produces OCI-compatible container images. So you can pull from Docker Hub or GitHub Container Registry and run those images. You can also push images you build to any standard registry.
container uses the open-source Containerization Swift package. That package handles low-level container, image, and process management. The tool requires a Mac with Apple silicon. Intel Macs are not supported. Apple supports container on macOS 26, which adds virtualization and networking enhancements. You can run it on macOS 15, but with networking limitations.
How container Runs Your Containers
Most macOS container tools run one shared Linux VM that hosts every container. Apple takes a different path. container runs a separate lightweight VM for each container you create. Apple describes three properties of this design:
- Security: Each container has the isolation of a full VM. A minimal set of core utilities and dynamic libraries reduces resource use and attack surface.
- Privacy: You mount only the data each VM needs, instead of sharing everything.
- Performance: These containers use less memory than full VMs. Boot times are comparable to containers in a shared VM.
The runtime integrates several macOS frameworks. It uses the Virtualization…
