I am developing a macOS app and want to check connectivity status. I’ve created a simple connectivity observer using NWPathMonitor; I use it as en environment object:

@Observable
class ConnectivityMonitor {
    private let queue = DispatchQueue(label: "ConnectivityMonitorQueue")
    private let monitor = NWPathMonitor()
    
    private(set) var isConnected: Bool = false
    
    init() {
        monitor.pathUpdateHandler = { [weak self] path in
            DispatchQueue.main.async {
                self?.isConnected = path.status == .satisfied
                print("network path changed: ", path.status)
            }
        }
        monitor.start(queue: queue)
    }
}

To check different connectivity statuses, I use Network Link Conditioner prefpane (I will call it NLC) provided with Xcode Additional Tools by Apple.

I don’t know why but NWPathMonitor does not respond to NLC profile changes.

For example; I set NLC profile to 100% Loss which means there is no internet connection on the network at all. But NWPathMonitor’s pathUpdateHandler is not called.

Do I miss something? Thank you.
