+# Bridging the gaps with the Tart Guest Agent
+
+We're introducing a new improvement for the Tart usability experience: a [Tart Guest Agent](https://github.com/cirruslabs/tart-guest-agent).
+
+This agent provides automatic disk resizing, seamless clipboard sharing for macOS guests (a [long-awaited](https://github.com/cirruslabs/tart/issues/14) feature), and the ability to run commands, without SSH and networking, using the new `tart exec` command.
+
+As of recently, we include this agent in all non-vanilla Cirrus Labs images, so you likely won't need to do anything to benefit from these usability improvements.
+
+Read on to learn why we chose to implement the agent from scratch in Golang, and which features we plan to add next.
+
+<!-- more -->
+
+## Existing solutions
+
+Tart uses the Virtualization.Framework, and the latter implemented a SPICE client some time ago, however, one piece was missing: the agent that runs inside the guest.
+
+The original [SPICE `vdagent` implementation](https://gitlab.freedesktop.org/spice/linux/vd_agent) only supports Linux. While [a fork](https://github.com/utmapp/vd_agent) from the UTM project adds macOS support, the long-term viability of maintaining this fork without upstreaming changes is uncertain.
+
+Moreover, if we were to add some extra functionality (as we did), there would be more than one agent binary to ship and install, which complicates maintenance and makes it harder to explain to users why we need a bunch of agent binaries.
+
+In the end, we decided to go with our own solution, one that would easily accomodate future ideas.
+
+## Rolling our own agent
+
+After carefully inspecting the [`vdagent` protocol](https://www.spice-space.org/agent-protocol.html) we've realized that the clipboard sharing is actually a small subset of the whole protocol, making it relatively simple to implement.
+
+Thanks to Golang, we were able to implement the protocol much faster than we could have with a lower-level language like C (with all due respect), which requires manual memory management and complex event loops.
+
+As for the command execution via `tart exec`, we've decided to go with gRPC with a rather simple protocol:
+
+![An visualization of gRPC protocol used by the Tart Guest Agent](../images/tart-guest-agent-grpc-protocol.png)
+
+For each `tart exec` invocation a new gRPC `Exec` bidirectional stream is established with the agent running inside a VM. After the gRPC stream is established, `tart exec` sends a command to execute to the guest and streams the I/O. Once the command terminates, `tart exec` collects the process exit code and quits with exactly that exit code.
+
+Using gRPC simplifies `tart exec` implementation because of code generation and forms a nice bridge between the host and the guest which allows us to easily expand the protocol later down the road when we decide to introduce new features.
+
+Thanks to [gRPC Swift](https://github.com/grpc/grpc-swift), which is built on top of [SwiftNIO](https://github.com/apple/swift-nio), we get [`async/await`](https://docs.swift.org/swift-book/documentation/the-swift-programming-language/concurrency/) support for free, further simplifying the `tart exec` logic.
+
+As for the Tart Guest Agent, the final result is a Golang binary that [can be customized](https://github.com/cirruslabs/tart-guest-agent?tab=readme-ov-file#guest-agent-for-tart-vms) depending on the execution context:
+
+* launchd global daemon — runs as a privileged user (`root`), has no clipboard access
+    * `--resize-disk` — resizes the disk when there's a free space at the end of a disk (assuming that one previously ran `tart set --disk-size`)
+* launchd global agent — runs as a normal user (`admin`), has clipboard access
+    * `--run-vdagent` — clipboard sharing
+    * `--run-rpc` — `tart exec` and new functionality in the future
+
+We’ve also introduced `--run-daemon` (which implies `--resize-disk`) and `--run-agent` (which implies both `--run-vdagent` and `--run-rpc`) to help run the most appropriate functionality based on the given context.
+
+## Future plans
+
+First, we'd like to thank our paid clients, without whom this feature wouldn't have been possible.
+
+[Become one now](../../licensing.md) and enjoy higher allowances for Tart VMs and Orchard workers—while helping ensure that our roadmap aligns with your company's needs.
+
+In the near future we plan to implement:
+
+* Linux support — to provide seamless experience for Linux guests too
+* a new `tart ip` resolver — to provide a more robust IP retrieval facility for Linux guests, which often struggle to populate the host's ARP table with their network activity
+* `tart cp` command — to copy files from/to guest VMs
+
+Stay tuned, and feel free to send us feedback on [GitHub](https://github.com/cirruslabs/tart) and [Twitter](https://x.com/cirrus_labs)!

+# Press Release: Cirrus Labs Successfully Enforces Its Fair Source License
+
+**New York City, NY – October 27th, 2025 – Cirrus Labs, Inc.**, a leading provider of platforms for digital transformation, today announced that it has reached a settlement agreement regarding a violation of its Fair Source License.
+
+<!-- more -->
+
+Cirrus Labs makes its Tart Virtualization Toolset, a leading virtualization toolset to build, run and manage macOS and Linux virtual machines (VMs) on Apple Silicon,
+freely available on GitHub under the Fair Source License, a source-available license. Tart is used by tens of thousands of engineers at no charge within its generous free‑use limits.
+Many large enterprises that need to exceed those limits support continued development through paid licenses. Cirrus Labs also uses Tart to power [Cirrus Runners](https://cirrus-runners.app/)
+— a drop‑in replacement for macOS and Linux runners for GitHub Actions — offered at a fixed monthly price for unlimited usage.
+
+Cirrus Labs discovered that, **despite a prior licensing request that was declined due to a conflict of interest**, another company used Tart in a manner that exceeded the license’s free‑use limits,
+in order to create a competing product.
+
+After several months of negotiations, the matter was settled and a settlement payment to Cirrus Labs was agreed upon.
+
+!!! quote "Comment by Fedor Korotkov, CEO of Cirrus Labs"
+    
+    As a company we embrace healthy competition that ultimately benefits the end user. Most of our users have no trouble complying with our license,
+    and even when they need something more than our free use limits, we can almost always grant them a license that fits their needs. **This was an exceptional case.**
+    We are pleased to have reached this settlement, which validates our source-available licensing strategy and reinforces our commitment to protecting our company and serving our community.
+
+Cirrus Labs was represented in this matter by [Jordan Raphael](https://byronraphael.com/attorneys/jordan-raphael/) of Byron Raphael LLP, a boutique intellectual property law firm,
+and [Heather Meeker](https://www.techlawpartners.com/heather), a well-known specialist in open source and source available licensing.
+
+The specific financial terms of the settlement and the identity of the counterparty remain confidential.
+

+## Headless machines
+
+Starting from macOS 15 (Sequoia), there's an undocumented requirement from [Virtualization.Framework](https://developer.apple.com/documentation/virtualization) (which Tart uses) to have an unlocked `login.keychain` available at the times when running a VM.
+
+Without an existing and unlocked `login.keychain`, the VM won't start with errors like:
+
+* `SecKeyCreateRandomKey_ios failed`
+* `Failed to generate keypair`
+* `Interaction is not allowed with the Security Server`
+
+Below you'll find a couple of workarounds for this behavior.
+
+### Log in via GUI at least once
+
+Connect to the headless machine via [Screen Sharing](https://support.apple.com/guide/mac-help/share-the-screen-of-another-mac-mh14066/mac) and log in to a Mac user account. If you haven't done already, you can enable Screen Sharing [via the terminal](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/connect-to-mac-instance.html#mac-instance-vnc).
+
+Logging in graphically will automatically create the `login.keychain`. Afterward, you have two options:
+
+* configure [automatic log in to a Mac user account](https://support.apple.com/en-us/102316)
+    * this will maintain a running user session (GUI) even after the machine reboots
+    * moreover, you can still lock the screen (either manually [or automatically](https://support.apple.com/guide/mac-help/change-lock-screen-settings-on-mac-mh11784/mac)), however, the security benefit of this is questionable
+* use `security unlock-keychain login.keychain` to unlock the login keychain via the terminal
+    * this command also supports the `-p` command-line argument, which allows you to supply a password and unlock non-interactively
+
+### Create and unlock the login keychain via the terminal
+
+Compared to the previous approach, this one is fully automated, but might stop working at some point in the future:
+
+```shell
+security create-keychain -p '' login.keychain
+security unlock-keychain -p '' login.keychain
+security login-keychain -s login.keychain
+```
+
+Note that this will create a `login.keychain` with an empty password. Consider supplying a different value to `-p` or omitting the `-p` to enter the password interactively.

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.
