OSX-KVM
Run macOS on QEMU/KVM. With OpenCore + Monterey + Ventura + Sonoma support now! Only commercial (paid) support is available now to avoid spammy issues. No Mac system is required.
I used Kholia's scripts[1] on Qemu with Virsh. I didn't have much trouble other than some SELinux permission issues which I resolved quickly.
iCloud/imessage have always been finicky with Hackintosh, but in my experience setting the correct serial number with appropriate Mac model is the key to resolve those issues.
With just couple of years of Hackintosh scene left before support for x86 Macs are dropped completely, a VM Hackintosh makes more sense to me than building a physical Hackintosh.

Project mention: Launch HN: C/Ua (YC X25) – Open-Source Docker Container for Computer-Use Agents | news.ycombinator.com | 2025-04-23
Thank you! If you're looking for a Docker alternative to something like e2b, we're planning to ship a containerized version of c/ua that also handles VNC and model hosting. Right now we're using the Lume CLI (https://github.com/trycua/cua/tree/main/libs/lume) with an API server on the host as a lightweight alternative, but the Docker setup will make it easier to self-host and extend. Would love to hear what kind of workloads or use cases you had in mind!

Project mention: Hacktivity Cyber Security Labs for individuals (advice please) | news.ycombinator.com | 2025-03-24
- Built on our open source SecGen framework (https://github.com/cliffe/SecGen)
We're currently using Hacktivity to teach 300+ university students weekly.
Launch special: $7/month (billed annually), which includes complete courses from ethical hacking to exploit development.
Having spent so much time in R&D, open source, and academic usage, we're looking for advice on effectively reaching individual learners without typical marketing tactics. What channels or approaches would you recommend? How do we spread the word about Hacktivity without coming across as spammy?
