Celesto gives computer-use agents disposable full macOS desktops on Apple Silicon via Lume
aniketmaurya · x · 2026-09-16
Developer aniketmaurya built Celesto on top of Cua's Lume, letting computer-use agents escape the Linux-only limitation with disposable full macOS desktops on Apple Silicon. Agents get a real macOS environment with:
- Safari and native apps, .dmg installers
- Persistent files across restarts and host-shared folders
- Normal Gatekeeper, SIP, and permission prompts
The project is open source. Lume is Cua's local VM manager for Apple Silicon Macs — installable with one script, supporting stable/nightly channels and exact version pinning; requires an M-series chip, macOS 13+, 8GB RAM (16GB recommended) and 50GB disk.
