My (naive?) hypothesis is this kind of expertise is why OpenAI chose to acquihire.
Not to sell Tart short (it is quite good), but it's "just" a wrapper around Virtualization.framework with a few extra pieces. This is the kind of thing that Codex driven by experts _should_ be able to build very easily.
Same; the reason everyone ran out to buy Mac Minis last month is it gave their Claw access to iMessage, their browser cookies, and a residential IP. Cirrus provides a way to provision and orchestrate MacOS VMs, which is exactly what I did for running Openclaw (for a minute …).
