-# Managing Virtual Machine
-
-## Creating from scratch
-
-Tart supports macOS and Linux virtual machines. All commands like `run` and `pull` work the same way regardless of the underlying OS a particular VM image has.
-The only difference is how such VM images are created. Please check sections below for [macOS](#creating-a-macos-vm-image-from-scratch) and [Linux](#creating-a-linux-vm-image-from-scratch) instructions.
-
-### Creating a macOS VM image from scratch
-
-Tart can create VMs from `*.ipsw` files. You can download a specific `*.ipsw` file [here](https://ipsw.me/) or you can
-use `latest` instead of a path to `*.ipsw` to download the latest available version:
-
-```bash
-tart create --from-ipsw=latest sequoia-vanilla
-tart run sequoia-vanilla
-```
-
-After the initial booting of the VM, you'll need to manually go through the macOS installation process. As a convention we recommend creating an `admin` user with an `admin` password. After the regular installation please do some additional modifications in the VM:
-
-1. Enable Auto-Login. Users & Groups -> Login Options -> Automatic login -> admin.
-2. Allow SSH. Sharing -> Remote Login
-3. Disable Lock Screen. Preferences -> Lock Screen -> disable "Require Password" after 5.
-4. Disable Screen Saver.
-5. Run `sudo visudo` in Terminal, find `%admin ALL=(ALL) ALL` add `admin ALL=(ALL) NOPASSWD: ALL` to allow sudo without a password.
-
-### Creating a Linux VM image from scratch
-
-Linux VMs are supported on hosts running macOS 13.0 (Ventura) or newer.
-
-```bash
-# Create a bare VM
-tart create --linux ubuntu
-
-# Install Ubuntu
-tart run --disk focal-desktop-arm64.iso ubuntu
-
-# Run VM
-tart run ubuntu
-```
-
-After the initial setup please make sure your VM can be SSH-ed into by running the following commands inside your VM:
-
-```bash
-sudo apt update
-sudo apt install -y openssh-server
-sudo ufw allow ssh
-```
-
-## Configuring a VM
-
-By default, a Tart VM uses 2 CPUs and 4 GB of memory with a `1024x768` display. This can be changed after VM creation with `tart set` command.
-Please refer to `tart set --help` for additional details.
-
-## Building with Packer
-
-Please refer to [Tart Packer Plugin repository](https://github.com/cirruslabs/packer-plugin-tart) for setup instructions.
-Here is an example of a template to build a local image based of a remote image:
-
-```hcl

-
-## Working with a Remote OCI Container Registry
-
-Tart supports interacting with Open Container Initiative (OCI) registries, but only runs images created and pushed by Tart. This means images created for container engines, like Docker, can't be pulled. Instead, create a custom image as documented above.
-
-For example, let's say you want to push/pull images to an OCI registry hosted at `https://acme.io/`.
-
-### Registry Authorization
-
-First, you need to login to `acme.io` with the `tart login` command:
-
-```bash
-tart login acme.io
-```
-
-If you login to your registry with OAuth, you may need to create an access token to use as the password.
-Credentials are securely stored in Keychain.
-
-In addition, Tart supports [Docker credential helpers](https://docs.docker.com/engine/reference/commandline/login/#credential-helpers)
-if defined in `~/.docker/config.json`.
-
-Finally, `TART_REGISTRY_USERNAME` and `TART_REGISTRY_PASSWORD` environment variables allow to override authorization
-for all registries which might useful for integrating with your CI's secret management.
-
-### Pushing a Local Image
-
-Once credentials are saved for `acme.io`, run the following command to push a local images remotely with two tags:
-
-```bash
-tart push my-local-vm-name acme.io/remoteorg/name:latest acme.io/remoteorg/name:v1.0.0
-```
-
-### Pulling a Remote Image
-
-You can either pull an image:
-
-```bash
-tart pull acme.io/remoteorg/name:latest
-```
-
-or create a VM from a remote image:
-
-```bash
-tart clone acme.io/remoteorg/name:latest my-local-vm-name
-```
-
-If the specified image is not already present, this invocation calls the `tart pull` implicitly before cloning.

Fedor KorotkovandClaude Opus 4.5	6189dc23af	Fix VM window not appearing on tart run (#1183 ) Restore the applicationDidFinishLaunching method that was accidentally removed in commit `b1e88e1` ("tart run: do not remove 'Edit' menu as its not present anymore"). That commit intended to remove the Edit menu removal code (since the menu no longer exists), but also removed the crucial activation code: - setActivationPolicy(.regular) - tells macOS this is a GUI app - activate(ignoringOtherApps:) - brings the window to the foreground Without these calls, the VM runs fine (SSH works) but no window appears on screen.
