MacOS Workers, or how I built my own Mac cloud
Tart is a small open-source CLI built by the Cirrus Labs folks that wraps Apple's Virtualization.framework. You give it an OCI-compatible image (basically a tarball with the macOS VM disk), it spins up a VM on Apple Silicon hardware in seconds. The image is reusable, you can layer on top of it, and it's the closest thing to "docker, but for macOS VMs" that exists today.

Jenkins as a Code, or how I stopped clicking around in the UI
macOS workers are their own special kind of hell. You can't just spin up a Mac VM in AWS the same way you spin up Linux. There's a whole ecosystem of hypervisors, licensing rules, and hardware constraints to deal with. This deserves its own post — and it's getting one. Part 2 will be all about macOS workers: Tart, virtualization on Apple Silicon, the trade-offs between self-hosted and cloud-mac providers, and how to make signing and notarization not feel like a horror movie.

Show HN: Lumier – Run macOS VMs in a Docker
The title is a bit misleading then :)
What’s the difference between this vs just using your lume CLI? Right now it feels like a worse interface to lume, but maybe I’m not getting a use case for this.
Also, any thoughts on https://github.com/cirruslabs/tart? (alas, not open source)

Cheetah: A Lightweight Virtual Machine Manager for macOS
the inability to log in with an Apple ID in a MacOS VM is a decision made by Apple. you can certainly sign without logging in, but I don't think you can submit to the store in a VM.
you can see how they build tart here, including signing and entitlements and so on: https://github.com/cirruslabs/tart/blob/main/.cirrus.yml

Apple M1 Mac as a Service
Boots in 5 minutes, minimum allocation of 24 hours, is "low stock" if you actually try to allocate one, and was recently "no stock". I'd be unsure if its actually available when you need it.
Would be nice to see a Virtualization.Framework as a service, such as with Tart [1], but perhaps there are performance and security issues when making those M1s multi-tenant. The license limits it to a maximum of two guest systems, and only for the purposes of software development and testing [2].

Anyone using QEMU arch64 on Apple M2/M1
I haven’t used UTM personally so I can’t vouch for that. There is also Tart.
