Namespace built custom datacenter racks using MacBook Pros to meet customer demand for macOS instances, overcoming supply chain issues with Mac Minis and addressing challenges like remote management, FileVault unlocking, and heat dissipation. Their platform leverages Apple’s Virtualization framework to run macOS VMs efficiently, optimizing image storage and distribution across hundreds of machines using layered sparse images and peer-to-peer techniques to handle large VM images. Despite Apple’s virtualization limits and network overhead, Namespace achieves robust performance and scalability to deliver cloud Mac instances with rapid OS and Xcode updates.
