Devin invites builders to tackle macOS sandboxes

This is a product prompt, not a sandbox launch—and that distinction matters: Devin is being positioned as the builder of agent infrastructure while the macOS execution layer remains open territory.

• –Devin already provides cloud agents with shell, browser, editor, and sandboxed compute environments.
• –macOS-native sandboxes would unlock serious Xcode, iOS, desktop-app, and Apple-specific automation workflows.
• –The hard problems are hardware capacity, VM isolation, entitlements, GUI access, secrets, snapshots, and reliable teardown at scale.
• –A focused wedge—ephemeral macOS environments for Xcode builds and testing—looks more practical than a general-purpose cloud Mac.
• –The post signals where agent infrastructure is heading: operating-system fidelity will become as important as model quality.
