Barn 0.9.2: signed Barn.app and explicit SSH/exec arguments

Fri, 30 Oct 2026 00:00:00 +0800

Released on 2026-10-30. Barn 0.x releases use GitHub’s pre-release channel.

Barn 0.9.2 includes the complete native macOS guest runtime in the Apple Silicon download and Homebrew installation. You can create Linux and macOS VMs after installing a single package, without installing Go or Xcode.

Changes

The Darwin arm64 archive contains barn, barn-hosts-helper, and Barn.app from the same source commit. All three executables use Developer ID signatures and are submitted together for Apple notarization; the app carries a stapled ticket and passes Gatekeeper assessment.
brew install pgsty/infra/barn installs the CLI, QEMU, helper, and native app. The CLI discovers the app under Homebrew’s libexec. macOS guests require Apple Silicon, macOS 27+, and a logged-in desktop session.
The helper is signed before its final SHA-256 is embedded in the CLI. Packaging checks the pair again after attaching the native payload to the release archive.
ssh, exec, mac ssh, and mac exec require -- before remote commands. SSH passes a command line to the guest shell; exec preserves individual arguments. Use sh -c with exec for pipelines or redirection.
Linux arm64/amd64 and Intel macOS continue to ship the CLI and helper for QEMU Linux guests.

The first macOS VM downloads Apple’s restore image and prepares a reusable base installation. Supply an existing compatible IPSW with barn mac setup --ipsw PATH to use a local restore image.
