Hi, can't activate system-extension. in any case getting Domain=OSSystemExtensionErrorDomain Code=8 "Invalid code signature or missing entitlements" (sometimes get code = 9) P.S. In debug running all is working. (The system is asking to activate sysex) Has to read huge amount of forum, samples, and docs. But no luck What and how i've tried steps which i've doing #- signing sysextension binaries with Developer ID Application #- signing system extension with Developer ID Application #- signing application with Developer ID Application #- checking all signatures with Developer ID Application #- building pkg installer #- signing installer with Developer ID Installer #- checking signing #- sending installer for notarization #- waiting for installer verification #- after success I call stapler staple #- When calling sysex activation I get (But the problem is persist when i've try to move signed app to application folder, or try to notarize zip) or in any case which possibly mention on forum, i've get sign command sample codesign --force --timestamp --options runtime --sign "Developer ID xxx" Also has to tried with ** --deep,** but no luck. Result of steps descrribed here: App has System Extension compatibility, Sysex haven't System Extension. App is used the same bundle id as in AppStore (also has to tried separate one, but no luck) In console just two informative message regarding it, but nothing specific default 01:08:04.745310+0200 sysextd client activation request for com.company.appName.PacketTunnelMacExternal default 01:08:04.745330+0200 sysextd attempting to realize extension with identifier com.company.appName.PacketTunnelMacExternal default 01:08:04.750996+0200 appName-Mac-External [0x13a9496f0] invalidated because the current process cancelled the connection by calling xpc_connection_cancel() Could you please assits with solve issue?

I found a problem where a process tries to connect to System Extension and connection is invalidated. XPC listener has to be disposed and initialized again. This happens when System Extension executes tasks in following order: NSXPCListener initialized NSXPCListener.resume() NSProvider.startSystemExtensionMode() Result: Connection is invalidated and not only that the client has to retry connection, nut also System Extension must reinitialize listener (execute step 1 and 2). However if I call NSProvider.startSystemExtensionMode() NSXPCListener initialized NSXPCListener.resume() It works as expected and even if the connection is invalidated/interrupted, client process can always reconnect and no other action is necessary in System Extension (no need to reinitialize XPC listener), In Apple docs about NSProvider.startSystemExtensionMode() it says that this method starts handling request, but in another online article written by Scott Knight I found that startSystemExtensionMode() also starts listener server. Is that right? PLease could you add this info into the docs if it is so? https://knight.sc/reverse%20engineering/2019/08/24/system-extension-internals.html I would like to use following logic: Call NSProvider.startSystemExtensionMode() only under certain circumstances - I have received some configuration that I need to process and do some setup. If I don't receive it, there is no reason to call startSystemExtensionMode() yet, I don't need to handle handleNewFlow() yet. Connect XPC client to System Extension under certain conditions. Ideally communicate with client even though System Extension is not handling network requests yet, that is without receiving handleNewFlow(). Basically I consider XPC and System Extension handling network requests as separate things. Is that correct, are they separate and independent? Does XPC communication really depend on calling startSystemExtensionMode()? Another potential issue: Is it possible that XPC listener fails to validate connection when client tries to connect before System Extension manages to complete init and park the main thread in CFRunLoop? Note: These querstions arose mostly from handling upgrades of System Extension (extension is already running, network filter is created and is connected and new version of the app upgrades System Exension). Thanks.

While attempting to load a Network extension with OSSystemExtensionRequest I keep getting a "didFailWithError error 1". SIP is disabled. Does anyone know what code 1 is and how to fix it?
