macOS 27 breaks Finder integration for file providers talking to servers on your local network. Even when ShellFish itself is allowed Local Network access, its Finder extension is still blocked: "Local network prohibited" on every connection. No prompt, and toggling the permission for the main app doesn't help. Internet servers and localhost work fine. Filed as FB24999927 with logs and a sysdiagnose. Boosts appreciated, hoping this reaches someone at Apple 🙏
