Tor Arne Vestbø d1bfda63fc Add --provisioning-opts flag to provision macOS guests on first boot (#1263)
Exposes Apple's macOS 27 guest provisioning API
(VZMacGuestProvisioningOptions) so a macOS guest can be set up
automatically on the first boot after restore.

The flag takes a comma-separated list of key=value pairs mapping 1:1 to
the API properties (fullName, username, password, logsInAutomatically,
enablesRemoteLogin). It is validated to require a macOS 27+ host and a
macOS VM.

The entire user-facing surface is gated behind
'#if arch(arm64) && compiler(>=6.4)' so the flag doesn't appear in help
on toolchains that lack the macOS 27 SDK, while the runtime
'#available(macOS 27, *)' check gates actual use against the host OS.

Tart is a virtualization toolset to build, run and manage macOS and Linux virtual machines (VMs) on Apple Silicon. Built by CI engineers for your automation needs. Here are some highlights of Tart:

  • Tart uses Apple's own Virtualization.Framework for near-native performance.
  • Push/Pull virtual machines from any OCI-compatible container registry.
  • Use Tart Packer Plugin to automate VM creation.
  • Easily integrates with any CI system.

Many companies are using Tart in their internal setups. Here are just a few of them:

Note: If your company or project is using Tart please consider sharing with the community.

Usage

Try running a Tart VM on your Apple Silicon device running macOS 13.0 (Ventura) or later (will download a 25 GB image):

brew install cirruslabs/cli/tart
tart clone ghcr.io/cirruslabs/macos-tahoe-base:latest tahoe-base
tart run tahoe-base
