what's even more alarming is how exploitable GitHub Trending itself is these days. you can get the star count to fork ratio right and you land on the front page, which then pulls in real organic stars

it reminds me of https://github.com/dockur/windows with its compose-style YAML over QEMU/KVM. The difference i'm seeing is scope: dockur ships curated OS images (Windows/macOS), while holos looks more li

Thanks - trajectory export was key for us since most teams want both eval and training data. On non-determinism: we actually handle this in two ways. For our simulated environments (HTML/JS apps like the Slack/CRM clones), we cont

Fair point - we just open-sourced this so benchmark results are coming. We're already working with labs on evals, focusing on tasks that are more realistic than OSWorld/Windows Agent Arena and curated with actual workers. If you w

Hey visarga - I'm the founder of Cua, we might have met at the CUA ICML workshop? The OS-agnostic VNC approach of your benchmark is smart and would make integration easy. We're open to collaborating - want to shoot me an email at

The author's differential testing (2.3M random battles) is great as final validation, but the real lesson here is that modular testing should happen during the port, not after. 1. Port tests first - they become your contract 2. Run uni

Fair point - both use VNC for unattended setup. The difference is implementation: Tart does it via a Packer plugin (Go), we built it natively in Swift with a customizable YAML schema that's less error-prone. User-facing difference is -

Thanks! On API call visibility - Lume's MCP interface doesn't expose outbound network traffic directly. It's focused on VM lifecycle (create, run, stop) and command execution, not network inspection. For agent observability,

MDM platforms can skip Setup Assistant, but they require the device to be pre-enrolled in Apple Business Manager before first boot - VMs can't be enrolled in ABM, so those hooks aren't available. defaults write only works after yo

Good catches, thanks! Just updated the page: Fixed the registry description—you're right, GHCR is an OCI registry. Both tools use OCI-compatible registries, we just default to GHCR/GCS. Added licensing to the "when to choose&

Thanks for the feedback! You're right that a proper comparison page beats hunting through GitHub issues. We just put one together (with some help from Claude Code, naturally): https://cua.ai/docs/lume/guide&#x

Thanks! On graphics - currently it's paravirtualized via Apple's Virtualization Framework, so basic 2D acceleration but no GPU passthrough. Fine for desktop use, web browsing, coding, productivity apps. Wouldn't recommend it

Nice, thanks for sharing! It'd be interesting to integrate MIST into lume's ipsw command - right now Apple's native features in Apple Vz only provides download links for the latest supported version of the host, so grabbing o

Both use Apple's Virtualization Framework, so core VM performance is similar. Main differences are around agent-first design (HTTP API, MCP server), unattended setup via VNC + OCR, and registry support for VM images. We've also bu

Yeah, Apple intentionally provides no unattended setup. Plus any process trying to control the UI programmatically needs explicit accessibility permissions, which defeats the purpose. So we just click through like a human would via VNC. Ver

We haven't observed any networking degradation with Lume on Tahoe so far - things have been working smoothly in our testing. Give it a try and let us know if you run into any issues!

Correct, Containerization APIs are Linux VMs specific. There's a kernel-level check in the Hypervisor framework that enforces the 2 VM limit, and bypassing it violates Apple's EULA. Nice technical deep-dive on the how here: https

LoganDark is right. I've personally never tried, and don't think it'd be easy for any macOS predating Apple Virtualization Framework. For that you'd need something like UTM since they're relying on QEMU - these conf

re: unattended setup. You're both right - Apple's official zero-touch setup requires MDM + DEP, which needs Apple Business Manager (and yes, a DUNS number). But for VMs specifically, DEP doesn't work anyway - VMs don't h

re: https://github.com/dockur/macos A closer comparison here is Lumier, which provides a "Docker-like" interface to spin up VMs with a noVNC server: https://cua.ai/docs/lume/guide&#x

Docker on Mac runs Linux containers inside a Linux VM - you can't run macOS in Docker. So if you need Claude / Codex / OpenCode to interact with: - macOS GUI apps (Xcode, Numbers, Safari, etc.) - macOS desktop automation (scr

Growing up in Italy in the 90s, Olivetti was already fading but still everywhere. My grandmother had a Lettera that I swear will outlive us all. Reading these comments is interesting—for most of you it's nostalgia for nice hardware. In

+1 to this. I’ve seen the same thing - once completion respects earlier flags, defaults matter less and the CLI becomes self-discoverable. Fish gets part of the way there, but having it modeled at the parser level feels like the missing pie
