Adds a new network config option allowMachLookup that allows specifying additional XPC/Mach service names to permit in the sandbox. This enables tools like 1Password CLI that require access to services not in the default allowlist. Supports both exact matches and prefix wildcards: - Exact: "com.1password.helper" - Prefix: "2BUA8C4S2C.com.1password.*" Closes anthropic-experimental#83

Any progress on getting this merged? Also required for running Playwright E2E tests in the sandbox, since it uses Chromium mach lookup |

👍 Currently having to exclude |

I just wanted to +1 this because I assume this will fix an issue that currently, for iOS development, you can't run the simulator (eg. for agentic testing) in the sandbox environment as it requires at least the following XPC services via mach-lookup. I don't feel competent enough to judge, but it seems to me this PR would provide an appropriate fix. |

Allow users to specify additional XPC/Mach service names in the sandbox profile via a new `allowMachLookup` string array config option. Services ending with `*` use global-name-prefix (wildcard matching); others use global-name (exact match). Use case: tools like 1Password CLI that require specific Mach services not in the default allowlist. Source: anthropic-experimental#92
