alt Hacker NewsYup it uses Apple Virtualization framework for virtualization. It makes it so I can't use the Claude Cowork within my VMs and that's when I found out it was running a VM, because it caused a nested VM error. All it does is limit functionality, add extra space and cause lag. A better sandbox environment would be Apple seatbelt, which is what OpenAI uses, but even that isn't perfect: https://news.ycombinator.com/item?id=44283454
I don’t have an opinion on how they should handle the nested VMs probably, but I very much disagree that Seatbelt is better. Claude Code (aka `claude`) uses it, and it’s barely good for anything.
Out of curiosity, why are you running Cowork inside a VM in the first place? What does that get you that letting Cowork use its own VM wouldn’t?
