As I mentioned in this thread https://developer.apple.com/forums/thread/695207 I want my containing app to be active after Mac restarts. I thought about something that could work - I wrote a "helper" embedded app which will be added to the login items, and after a restart this "helper" app will open the containing app. However, after archiving the project (with developer ID, it will be distributed outside the App Store), I see the following error at the Console: Non-fatal error enumerating at , continuing: Error Domain=NSCocoaErrorDomain Code=260 "The file “PlugIns” couldn’t be opened because there is no such file." UserInfo={NSURL=PlugIns/ -- file:///Applications/MyMainApp.app/Contents/Library/LoginItems/LauncherApplication.app/Contents/, NSFilePath=/Applications/MyMainApp.app/Contents/Library/LoginItems/LauncherApplication.app/Contents/PlugIns, NSUnderlyingError=0x7fc5cb02c6f0 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}} I see that there's really no plugin folder, but why? Is it a certificate/signing issue?

I've developed a system-extension custom VPN app for macOS. As expected, the containing app is running under 'user' permissions, and the system-extension is running under 'root' permissions. The containing app and the sys-ext can create (and save) log files. The containing app has a button to 'collect' the logs from both the containing app and from the extension. However, it can't really access to the extension's logs since it's under root/ What I'm doing is to ask the extension to send the logs via IPC, but what should I do if the VPN is not connected? In this case the extension is not running, and I can't get it's logs. Is there another way to get the file, or maybe to write logs from the extension to somewhere directly accessible to the containing app?

I've developed a system-extension custom VPN app for macOS, which is in use by some internal testers. The app works fine, except for one user, which can't connect to the VPN. I saw that on his machine, the system extension is getting terminated, very shortly after he's approving it. Sometime it happens while he's trying to connect, but sometimes it happens even without a connection attempt, he's just approving the sysExt and wait. I saw at the logs the following lines: sysextd: [com.apple.sx:StateChange] **** advancing state from activated_enabling to activated_enabled sysextd: observer for **** reached success: activated_enabled sysextd: [com.apple.sx:XPC] client connection (pid 667) invalidated 2022-01-12 21:45:50.844914+0200 0x26fa Activity 0xf149 496 0 sysextd: (Security) SecTrustEvaluateIfNecessary 2022-01-12 21:45:50.926046+0200 0x26fa Default 0x0 496 0 sysextd: request contains no authorizationref 2022-01-12 21:45:50.926390+0200 0x26fa Default 0x0 496 0 sysextd: returning cdhash for arbitrary arch x86_64 of extension **** sysextd: [com.apple.sx:XPC] client connection (pid 1103) invalidated nesessionmanager: [com.apple.networkextension:] Adding event subscription 775 for provider *** with extension point com.apple.networkextension.packet-tunnel ... ... sysextd: received request to remove MDM payload with UUID **** sysextd: removed MDM payload with UUID **** sysextd: MDM payload change results in changed decision for Extension **** from Allow to UserOption sysextd: deactivateExtension called for **** in state "activated_enabled" sysextd: [com.apple.sx:StateChange] extension **** advancing state from activated_enabled to terminating_for_uninstall Is this issue related somehow to MDM profiles?

I've developed a custom VPN system extension (macOS, Packet Tunnel Provider). On a first installation, the user has to allow installation of the system extension (via  Security & Privacy). My question is, what should happen when the user updates the app to a newer version - will he get the 'allow system extension installation' popup again? Or is it a 'one time popup' only?

Hi I've developed a custom VPN app for macOS (system-extension, Packet Tunnel Provider), and I have the following problem: I'm connected vie Ethernet only (not Wi-Fi). I configured on the Ethernet interface HTTP and HTTPS proxies. I'm connecting to my VPN: If I'm using a 'full tunnel' - the traffic won't pass to the Ethernet proxies, this is expected If I'm using a split tunnel - even the routes included on the tunnel will reach the Ethernet proxies, this is not expected. Am I right that this behavior is not expected? How can I fix this issue?

I have some questions regarding life cycle of Packet Tunnel Provider: I have some static vars at the PacketTunnelProvider. The user connected to the VPN, then disconnected, so I called the relevant compilation handler. After some time, the user will start VPN again, PacketTunnelProvider will be recreated. Will it use the same class as before, and all static vars will hold their last value? Or would it create a new PacketTunnelProvider? Is it the same behavior for Network Extension vs System Extension? Is it the same behavior for macOS vs iOS? What about running threads? If I created a thread, and then I called the completion handler, will this thread continue to run? P.S If I'm adding exit(0) before 'quitting' the Packet Tunnel Provider, it will force cleaning the memory. But I guess it's not a good behavior for a System Extension to use exit(0) class PacketTunnelProvider: NEPacketTunnelProvider { static var isInitiated = false ... } override func startTunnel(options: [String : NSObject]?, completionHandler: @escaping (Error?) -> Void) { ... PacketTunnelProvider.isInitiated = true ...

I've developed a system-extension for macOS (Packet Tunnel Provider, Developer ID, distribution outside the App Store). There's a scenario where I want to present some webpages with the WebKit. It works fine, but on of my testing Macs the webpage display the page for a split second, and then becomes white. I saw that the WebKit crashed, but I'm not sure why. I attached the crash report. Also, at the crash report, I saw this: "is_first_party":1,"bug_type":"309" Did my application cause this crash? Any advise on how to debug it or on how can I prevent if from happening? com.apple.WebKit.WebContent-2021-12-12-063048.txt

I'm implementing a VPN client using PacketTunnelProvider.I have a C code that talk to my sever, and this C code also has callbacks to my Swift code.In those callbacks I just need to send / receive packets.I do not need to create a tunnel with the server, because the C code does it for me.So my question is, how to get all the packets ? I tried doing it with packetFlow, but without any success.(And as for the moment, i'm trying to do it at the startTunnelWithOptions function, but not sure if it's the right place)Thanks!

-I've implemented a VPN app (with Packet Tunnel Provider).I have an ovserver for NEVPNStatusDidChangeNotification.When the user press the "connect" button, 90 % of the time I get the notifications where the connection.status goes from Disconnected to Connecting and then to Connected.But I've already encounterd several cases, where the connection succeeded, but the notifications I got wereDisconnected -> Connecting - > InvalidAnd as I said, the connection been made and the VPN had been activated, so why I got the Invalid state ?Edit:Those are some of the system logs:name = <40-char-str> identifier = some-identifier-I-dont-know-1 applicationName = myApp application = myAppBundle grade = 1 VPN = { enabled = YES onDemandEnabled = YES onDemandRules = ( { action = connect interfaceTypeMatch = any }, ) protocol = { type = plugin identifier = some-identifier-I-dont-know-2 serverAddress = <16-char-str> username = <24-char-str> password = { identifier = some-identifier-I-dont-know-1 domain = user } passwordReference = <67656e70 00000000 00000417> identityDataImported = NO disconnectOnSleep = YES disconnectOnIdle = NO disconnectOUpdated network agent (inactive)vpnStatusDidChange: InvalidNESMVPNSession in state NESMVPNSessionStateIdle: update configuration NESMVPNSession: Received a start command from myApp

I've developed a VPN app for iOS and macOS with Packet Tunnel Provider.Once the VPN is enabled all the traffic should go via the VPN. The VPN is configured to be on demand (isOnDemandEnabled is set), with a rule to always connect.There are some cases where this configuration might cause a problem -When the user goes to a place with a captive portal, the VPN won't be able to connect (because the user will first need to login to the captive portal), but the user also won't be able to login to the captive portal (because all traffic triggers the network extension).In such a case, I need that the captive portal will be shown to the user, and I also need to exclude at least some of the traffic from the VPN, so the user would be able to login to the captive portal (but I don't want to open all traffic, just the traffic needed for the login).Is there any API for those cases? If the answer is no, I'll try to detect this case at the Extension. But I won't be able to open the captive portal from there, so the only thing I would be able to do is to display a message to the user, correct?

I've implemented a custom system-extension VPN (Packet Tunnel Provider) for macOS. At the extension, I need to use a 3rd party dynamic lib. The steps I did: Build phases: Copy files, with Frameworks destination Link Binary With Libraries Build Settings: I set 'Dynamic Library Install Name', 'Dynamic Library Install Name Base', and 'Library Search Path' to the lib folder I set 'Header Search Path' to the headers folder But when running the extension, it's crashing with the error Termination Reason: Namespace DYLD, Code 1 Library missing Library not loaded: @loader_path/somelib.dylib And Reason: tried: '/Library/SystemExtensions/A1111-someID-11111/com.myapp.myappSysExtension.systemextension/Contents/MacOS/libwavmodapi.dylib' (no such file), '/usr/local/lib/libwavmodapi.dylib' (no such file), '/usr/lib/libwavmodapi.dylib' (no such file) (terminated at launch; ignore backtrace) Any idea what I'm doing wrong here? Also, is it even possible to use dynamic libs from a sys-ext?

I've implemented a VPN app (with Packet tunnel Provider) for MacOS.Each user has a password, which I'm saving at the keychain with a persistentReference.For some users (not many), the app fails to save the password and I got error -25308 which is User interaction is not allowed.Why does it happening and how can I solve it?

I've implemented a custom VPN system extension for macOS (Packet Tunnel Provider). I created a tunnel, and I have a VPN connection, with the default (IPv4) routes. My question is about sending traffic which was originated at the extension, via the tunnel. Is it possible to create a BSD socket at the extension, and bind it to a specific interface, so the traffic (that was created from the extension) for this socket will be routed via the tunnel?

I've implemented a VPN app with Packet Tunnel Provider for macOS.To send the packets, I'm using BSD sockets.I noticed that when sending big files (1GB), in most of the time the uploading fails, and the relevant errors I see at the console are the following errors:[Extension com.myExtension]: IPC detached NESMVPNSession[Primary Tunnel:My Company - myUserName:6EF9650B-D1DA-418B-B617-AE0874DDCBD3:(null)] in state NESMVPNSessionStateRunning: plugin NEVPNTunnelPlugin(com.MyContainingApp]) did detach from IPC [NOTICE] : networking grace period is over for #lifetime boringssl_context_message_handler(2257) [C6.1:2][0x1048aeac0] Writing SSL3_RT_ALERT 2 bytes boringssl_context_handle_warning_alert(1892) [C6.1:2][0x1048aeac0] write alert, level: warning, description: close notify boringssl_session_disconnect(539) [C6.1:2][0x1048aeac0] SSL_shutdown 0 nw_flow_disconnected [C6.1 20.185.73.23:443 cancelled socket-flow ((null))] Output protocol disconnected nw_connection_report_state_with_handler_on_nw_queue [C6] reporting state cancelled Connection 6: destroyed nw_protocol_boringssl_remove_input_handler(1012) [C6.1:2][0x1048aeac0] nw_protocol_boringssl_remove_input_handler forced true nw_protocol_boringssl_remove_input_handler(1030) [C6.1:2][0x1048aeac0] Transferring nw_protocol_boringssl_t handle back into ARC for autoreleaseSo I'm guessing it's related to "did detach from IPC" or to "SSL3_RT_ALERT 2 bytes", but what's the next step here? How can I try to figure out what's causing this?P.S: It seems that the VPN stays connected and functional, it's just the uploading that fails.

I have a question very similar to this one, from 5 years ago: https://developer.apple.com/forums/thread/75710 I have a macOS app, in which I have a webview, which loads a login page for the user. The user can log in using an SSO, and the SSO login process might require verifying that a certificate is installed on the user's machine. The certificate and the user login credentials aren't related to my app in any way. The certificate should be already installed at the Keychain. My question is related to the function webView(_ webView: WKWebView, didReceive challenge:) Should I implement this function? As I said, the certificate is not related to my app, so it would be better to let the OS handle the challenge, if possible. In case I have to implement this function, is there any way for my app to answer this challenge? Any example on how to do it?
