Failed to open System Settings: {}

Error message

Failed to open System Settings: {}

What it means

request_screen_recording_permission (macOS only) spawns the system 'open' binary with a System Settings deep link to send the user to Privacy & Security. The error means Command::spawn itself failed - the child process could not be created. It does not mean Settings failed to open, and it says nothing about the permission state.

Solutions

1. Invoke open by absolute path: /usr/bin/open
2. Launch the app from a normal login session (Finder or a terminal with the user's full environment)
3. If spawn still fails, treat it as best-effort: show the user the manual path (System Settings > Privacy & Security) instead of erroring

Example fix

// before
let result = Command::new("open")
    .arg("x-apple.systempreferences:com.apple.preference.security")
    .spawn();

// after - absolute path survives stripped PATH environments
let result = Command::new("/usr/bin/open")
    .arg("x-apple.systempreferences:com.apple.preference.security")
    .spawn();

// Check the binary by absolute path before spawning
let open_path = if std::path::Path::new("/usr/bin/open").exists() {
    "/usr/bin/open"
} else {
    "open"
};

Treat spawn failure as best-effort: log warn!, then return Ok(()) after telling the user how to open System Settings manually (System Settings > Privacy & Security > Audio Capture). Never block the permission flow on this call.

When it happens

Trigger: The 'open' executable is not resolvable via PATH because the app was launched from a stripped environment (launchd, ssh session, some IDE runners); a sandbox or MDM policy blocks child-process creation; security software intercepts process spawning.

Common situations: App auto-started by a launcher daemon or run over ssh where PATH lacks /usr/bin; endpoint security blocking process creation; unusual macOS hardening configurations.
