One app, one CLI, nothing else to install.
Download 1VMTool for Apple silicon — one signed app and one CLI, no bundled hypervisor and no account. Every release, checksum and signature is a public GitHub artifact, and the free tier is the same build.
What lands on your Mac
- 1VMTool.app — the window, the machine library, the Metal console and the Docker workspace.
- The
1vmcommand line, in the same bundle. Create, start, snapshot, reset and dispose of machines from a script, with--jsonon every command that returns anything. - A local MCP endpoint, off until you turn it on, so a coding agent can drive machines under a scoped token.
Nothing is downloaded behind you. Guest images, the Debian base for the managed Docker engine, and any prepared-environment recipe are fetched only when you ask for them, and the app says how big each one is first.
Verify what you downloaded
Each release publishes SHA256SUMS.txt beside the artifacts. Compare it against the file you have before opening it:
shasum -a 256 ~/Downloads/1VMTool-0.5.0.dmgThe app is signed and notarized as well, so Gatekeeper checks it independently — but a checksum is the one verification that does not depend on trusting the machine you downloaded it on.
Previous releases
Older builds stay published. Every version links to its own notes; the changelog is the same history read as prose.
| Version | Released | Size | Notes |
|---|---|---|---|
| 0.4.0 | 9 Sept 2026 | 17.8 MB | Release notes |
| 0.3.0 | 8 Sept 2026 | 17.5 MB | Release notes |
Free is the same build
There is no trial clock and no watermark. Two machines, one running at a time, every guest and both engines at full speed. What Pro lifts is a list of counts, not a list of features.
Frequently asked questions
What do I need to run 1VMTool?
macOS 26 or later on an Apple silicon Mac. There is no Intel build: both engines are built on Apple's arm64 virtualization stack, and an Intel Mac has no path to them.
Is there anything else to install?
No. The app and the 1vm command line ship in the same signed bundle, and there is no QEMU, no Homebrew formula and no kernel extension to add. The managed Docker engine, when you turn it on, downloads its own Debian base image the first time.
Is the download the free version or the paid one?
The same build is both. Free runs it with two machines in the library and one running at a time; a Pro licence key lifts those caps in place. There is no separate paid installer and no trial that expires.
Is the app signed and notarized?
Yes. Tag builds produce signed, notarized macOS artifacts, and the checksums and signatures are published alongside the DMG in the releases repository so a download can be verified before it is opened.
How do updates work?
In-app, through Sparkle, from the same public releases repository. The updater fetches a .zip enclosure rather than the DMG — which is why the download counts on this page only follow the DMG, and describe new installs rather than updates.
Where do older versions live?
Every published release stays up. The archive below links each version's notes, and the full set with checksums and signatures is on the GitHub releases page.
