CLI-first VM automation
Updated October 3, 2026 Beta
MacVisor vs. Tart
Tart is a CLI-first automation tool for building, distributing, and running macOS and Linux VM images. Its standout feature is OCI registry integration, with Orchard available for clustered orchestration. MacVisor is a native local VM manager: a GUI and CLI over the same VMs, cloud-image dev VMs set up by cloud-init, persistent background VMs, snapshots, templates, custom networks with a host-enforced firewall, guest integration, and storage operations.
Side-by-side
Features and capabilities
Current as of October 3, 2026
| Capability |
MacVisor
| Tart |
|---|---|---|
| User interface | ✓ Native GUI library, settings, dashboard, snapshot list, and display windows, plus the mvz CLI. | ◐ CLI-first; tart run can show a VM display but there is no comparable fleet GUI. |
| Guest operating systems | ✓ macOS (installers for macOS 14, 15, 26, and 27, or your own IPSW) and ARM64 Linux. | ✓ macOS and ARM Linux. |
| Cloud images and cloud-init | ✓ A signed catalogue of vendor cloud images (Ubuntu, Debian, Fedora, Rocky Linux, AlmaLinux, CentOS Stream, openSUSE Leap, Oracle Linux, Alpine), plus import of your own qcow2, raw, or xz images and .ipsw installers. cloud-init is a settings page in the app and a set of create flags in the CLI: account, hostname, SSH keys, user-data, container runtime. | ◐ Pre-built macOS and Linux images pulled from OCI registries; images are customised with Packer rather than cloud-init at first boot. |
| Container runtimes | ✓ containerd, Docker, Podman, or k3s, opt-in in the New VM form or with --runtime (none by default). mvz docker <vm> forwards the VM's Docker or Podman API to a socket on the Mac through the guest agent with no network setup, and creates a docker context for it. | ◐ Not part of the VM tool; whatever the pulled image contains. |
| Guest agent installation | ✓ Zero-touch installation: cloud-init installs the agent in Linux VMs, and on macOS 27 guests MacVisor creates the account and installs the agent itself over SSH on the first boot. macOS 26 and earlier guests install it by hand from the attached volume. | ◐ No guest agent; access is over SSH, with directory mounts via VirtioFS. |
| CLI and API | ✓ The mvz CLI has full parity with the app (create, shell, exec, lifecycle, snapshots, clones, networks, ports, files, tasks, service), with --json output and documented exit codes. | ✓ Comprehensive tart CLI; Orchard adds a REST API for clustered operation. |
| VM process and control-plane isolation | ✓ One runner process per VM. Quitting the app, or restarting MacVisorService, does not stop running VMs. | ✓ Yes for VM-to-VM isolation: each tart run invocation owns one VM, with no shared GUI or local control plane. Ending that invocation stops only its VM. |
| Image distribution | ◐ Local templates and .macvisor import/export; no OCI registry support today. | ✓ Push and pull VM images through OCI-compatible registries. |
| Snapshots and saved state | ✓ Disk-only and live snapshots of running Linux and macOS guests, suspend and resume with saved state, pause, VMs shut down or suspended to disk when the Mac logs out or restarts (your choice), and revert with an optional safety snapshot. | ◐ Image cloning is central; a comparable snapshot manager is not documented. |
| Templates and cloning | ✓ Templates and instant linked clones on ASIF disk layers (a clone shares a sealed base and stores only its own writes), with flatten and trim. | ✓ tart clone copies an image (APFS-efficient on the same volume). |
| Storage locations and migration | ✓ Several storage locations on internal, external, or network volumes, with cold migration of stopped VMs and warm migration that suspends, moves, and resumes a running VM in one step. | ◐ VMs live under ~/.tart; distribution is through registries rather than local storage locations. |
| Guest integration | ✓ macOS and Linux agents over vsock carry mvz shell and exec, the per-VM Docker socket, clipboard, bidirectional file transfer, port tunnels, and live IP information; VirtioFS shared folders. | ◐ Directory mounts and SSH-oriented access; optimized for automated jobs. |
| Network modes and named segments | ✓ Default NAT and bridging, plus named shared (NAT) and host-only networks; every VM is reachable by name as <vm>.mvz. | ◐ Default shared NAT, bridge, host-only, and Softnet modes are available per run; persistent named shared or host-only networks are not documented. |
| 802.1Q VLAN bridge creation | ✓ Creates host VLAN interfaces (tags 1–4094) and bridges VM NICs or shared-network uplinks to them. | ◐ Tart can bridge an existing host interface; built-in host VLAN-interface creation is not documented. |
| DHCP and address reservations | ✓ Per-network DHCP with MAC-to-IPv4 reservations (mvz networks reserve), within vmnet's limits on macOS 27: a shared network re-picks its subnet when it is recreated, and a host-only network with a fixed subnet gets no DHCP at all. | ◐ The vmnet DHCP lease duration and default subnet can be tuned, but MAC-to-address reservations are not documented. |
| Network port forwarding | ✓ TCP/UDP NAT rules on shared networks, plus live per-VM TCP and UDP tunnels through the guest agent; cloud-image VMs forward the ports they listen on automatically. | ◐ Softnet can expose TCP ports per VM; UDP and named-network NAT forwarding are not documented. |
| Per-network firewall | ✓ Host-enforced IPv4 pf policy per network: inbound and outbound defaults with ordered allow/deny rules by protocol, CIDR, and port, set from the app or mvz networks firewall. IPv4 only; traffic between VMs on the same segment is not filtered. | ◐ Softnet provides per-VM IPv4 CIDR allow/block policy, but not per-network directional protocol and port rules. |
| Network service controls | ✓ Per-network DHCP, DNS proxy, NAT44, NAT66, and IPv6 router-advertisement switches, plus IPv4/IPv6 and MTU settings. | ◐ vmnet and Softnet expose selected subnet, lease, and isolation settings, not an equivalent named-network DNS/NAT44/NAT66/IPv6 RA switch set. |
| Graphics acceleration | ✓ Apple's accelerated graphics device for macOS guests, sharing the host GPU; Linux guests use Virtio graphics. | ◐ Apple Virtualization graphics; the CLI/CI focus makes interactive display secondary. |
| Multi-host orchestration | − Not available today. | ✓ Orchard can manage Tart VMs across an Apple Silicon host cluster. |
| Cost | ✓ Free 30-day trial key. MacVisor 27 Professional ($49, one individual) and Business ($99, organisations) are one-time licenses for one Mac covering every 27.x update; Enterprise starts at $99 per Mac per month, billed annually for 10 or more Macs, with 24x7 support and an SLA, by quote. Every edition has every feature. | ✓ Free; source-available under FSL-1.1-ALv2, converting to Apache 2.0 after two years. |
Where MacVisor wins
- A native GUI and the mvz CLI over the same VMs: library, settings, dashboard, snapshot list, and VM windows, alongside full command-line parity with --json output.
- Linux VMs from a signed catalogue of vendor cloud images, set up by cloud-init from the GUI or one mvz create command (account, SSH keys, and, when you ask, a container runtime and your home folder), with your own images importable from a file.
- Zero-touch guest agents: installed by cloud-init on Linux, and by MacVisor itself on macOS 27 guests after it creates the account.
- Snapshots (disk-only and live) plus suspend/resume and a choice of shutdown or suspend at logout, where Tart documents image cloning rather than a snapshot manager.
- A background service with one runner process per VM, so VMs outlive the shell that started them, with autostart at login.
- Lab networking with named shared and host-only segments, VLANs, DHCP reservations, <vm>.mvz names, port forwards, and a per-network firewall enforced on the Mac. To our knowledge it is the only Mac VM app with host-enforced per-network firewall rules.
Where Tart wins
- OCI-compatible registry push and pull for VM images.
- CLI-first workflow for CI/CD and reproducible automation.
- Packer and CI integrations, plus Orchard REST API orchestration for clusters.
- Straightforward macOS/Linux image creation, cloning, directory mounts, and SSH workflows.

FAQ
Common questions
Is MacVisor an alternative to Tart for CI? +
Partly. MacVisor has a CLI with full GUI parity and --json output, cloud-image VMs set up by cloud-init, templates and linked clones, headless starts, autostart, and serial consoles, but it does not match Tart for OCI image distribution, Packer integration, or multi-host orchestration.
Which is better for interactive VM management? +
MacVisor fits that workflow. It has a native VM library, settings, VM windows, a dashboard, networks, storage views, and a snapshot list, and the same VMs are controlled by mvz. Tart is primarily a terminal and automation tool.
Do both use Apple Virtualization? +
Yes. Both target Apple Silicon and use Apple Virtualization for native macOS and Linux virtual machines.
Sources and methodology +
Competitor capabilities come from official product pages, documentation, and repositories. MacVisor claims reflect the beta implementation reviewed on October 3, 2026. For VM process isolation, “Partial” means the available official material does not establish that running VMs survive termination of both the GUI and control plane, and that behavior was not independently tested. For advanced networking, “Partial” also covers edition or backend limits and cases where official material does not explicitly establish an equivalent persistent-network capability.
