Hello, I'm having some problems when install my Packet Tunnel network extension as system extension on my mac(macos 15.0).
It stuck on Validation By Category. (it works well as NE app extension on ios)
systemextensionsctl list
--- com.apple.system_extension.network_extension
enabled active teamID bundleID (version) name [state]
<...> com.myteam.balabalabla.ne (1.0/1) - [validating by category]
This is my install System Extension Code sample
public class SystemExtension: NSObject, OSSystemExtensionRequestDelegate {
private let forceUpdate: Bool
private let inBackground: Bool
private let semaphore = DispatchSemaphore(value: 0)
private var result: OSSystemExtensionRequest.Result?
private var properties: [OSSystemExtensionProperties]?
private var error: Error?
private init(_ forceUpdate: Bool = false, _ inBackground: Bool = false) {
}
// some request function i overwrite
public func activation() throws -> OSSystemExtensionRequest.Result? {
let request = OSSystemExtensionRequest.activationRequest(forExtensionWithIdentifier: FilePath.packageName + ".myNeName", queue: .main)
request.delegate = self
OSSystemExtensionManager.shared.submitRequest(request)
semaphore.wait()
if let error {
throw error
}
return result
}
public func getProperties() throws -> [OSSystemExtensionProperties] {
let request = OSSystemExtensionRequest.propertiesRequest(forExtensionWithIdentifier: FilePath.packageName + ".myNeName", queue: .main)
request.delegate = self
OSSystemExtensionManager.shared.submitRequest(request)
semaphore.wait()
if let error {
throw error
}
return properties!
}
public nonisolated static func install(forceUpdate: Bool = false, inBackground: Bool = false) async throws -> OSSystemExtensionRequest.Result? {
try await Task.detached {
try SystemExtension(forceUpdate, inBackground).activation()
}.result.get()
}
public nonisolated static func uninstall() async throws -> OSSystemExtensionRequest.Result? {
try await Task.detached {
try SystemExtension().deactivation()
}.result.get()
}
}
// And other methods
I follow this post Your Friend the System Log and use this command line to collect log. After I initiated the system extension request
sudo log collect --last 5m
Here is my log (),I only pasted some code snippets that caught me, full version see attachments.(only include com.apple.sysextd), if need more, plz ask me.
1. Some policy missing
```log

And when i debug the System Extension code i notice the request Error catch by didFailWithError
public func request(_: OSSystemExtensionRequest, didFailWithError error: Error) {
self.error = error
semaphore.signal()
}
error is
OSSystemExtensionErrorDomain code 1
This problem has been bothering me for a long time, I would appreciate any help, if need more info, comment, thank you.
