Hi everyone, I'm developing a C++ plugin (.bundle) for a third-party host application (Autodesk Maya) on macOS, and I'm finalizing the design for our licensing system. The plugin is distributed outside the Mac App Store. My goal is to securely store a license key in the user's Keychain. After some research, my proposed implementation is as follows: On activation, store the license data in the user's login keychain as a Generic Password (kSecClassGenericPassword) using the SecItem APIs. To ensure the plugin can access the item when loaded by Maya, I will use a specific Keychain Access Group (e.g., MY_TEAM_ID.com.mywebsite). The final .bundle will be code-signed with our company's Developer ID certificate. The signature will include an entitlements file (.entitlements) that specifies the matching keychain-access-groups permission. My understanding is that this combination of a unique Keychain Access Group and a properly signed/entitled bundle is the key to getting reliable Keychain access. This should also correctly trigger the one-time user permission prompt on first use. Does this sound like the correct and most robust approach for this scenario? Are there any common pitfalls with a plugin's Keychain access from within a host app that I should be aware of? Thanks for any feedback!

Has anyone here encountered this? It's driving me crazy. It appears on launch. App Sandbox is enabled. The proper entitlement is selected (com.apple.security.files.user-selected.read-write) I believe this is causing an issue with app functionality for users on different machines. There is zero documentation across the internet on this problem. I am on macOS 26 beta. This error appears in both Xcode and Xcode-beta. Please help! Thank you, Logan

Hi, I'm working on developing my own CryptoTokenKit (CTK) extension to enable codesign with HSM-backed keys. Here's what I’ve done so far: The container app sets up the tokenConfiguration with TKTokenKeychainCertificate and TKTokenKeychainKey. The extension registers successfully and is visible via pluginkit when launching the container app. The virtual smartcard appears when running security list-smartcards. The certificate, key, and identity are all visible using security export-smartcard -i [card]. However, nothing appears in the Keychain. After adding logging and reviewing output in the Console, I’ve observed the following behavior when running codesign: My TKTokenSession is instantiated correctly, using my custom TKToken implementation — so far, so good. However, none of the following TKTokenSession methods are ever called: func tokenSession(_ session: TKTokenSession, beginAuthFor operation: TKTokenOperation, constraint: Any) throws -> TKTokenAuthOperation func tokenSession(_ session: TKTokenSession, supports operation: TKTokenOperation, keyObjectID: TKToken.ObjectID, algorithm: TKTokenKeyAlgorithm) -> Bool func tokenSession(_ session: TKTokenSession, sign dataToSign: Data, keyObjectID: Any, algorithm: TKTokenKeyAlgorithm) throws -> Data func tokenSession(_ session: TKTokenSession, decrypt ciphertext: Data, keyObjectID: Any, algorithm: TKTokenKeyAlgorithm) throws -> Data func tokenSession(_ session: TKTokenSession, performKeyExchange otherPartyPublicKeyData: Data, keyObjectID objectID: Any, algorithm: TKTokenKeyAlgorithm, parameters: TKTokenKeyExchangeParameters) throws -> Data The only relevant Console log is: default 11:31:15.453969+0200 PersistentToken [0x154d04850] invalidated because the client process (pid 4899) either cancelled the connection or exited There’s no crash report related to the extension, so my assumption is that ctkd is closing the connection for some unknown reason. Is there any way to debug this further? Thank you for your help.

Hi! I'm trying to add Sign in with Apple to my macOS app. I enabled this capability from the developer portal and created the corresponding certificate & provisioning profile (both of type Developer ID Application.) However, Xcode keeps prompting me that the profile doesn't support Sign in with Apple. If I enable Automatically manage signing from Xcode, I can build and run the app but not distribute. If I turn it off and use the profile I got, it just keeps showing the errors below and doesn't even let me build.

I am new to swift development, and it's possible that I'm missing something fundamental/obvious. If so, I apologize in advance. My team is developing an application for iPadOS using SwiftUI, and I'm trying to accomplish something similar to what the original inquirer is asking for in this thread: https://aninterestingwebsite.com/forums/thread/725152. The only difference is that I'm trying to use a PIV smart card to achieve authentication to a server rather than digitally sign a document. Unfortunately, I'm getting stuck when attempting to run the list() function provided in the accepted answer to the post mentioned above. When attempting to call SecItemCopyMatching(), I'm getting a -34018 missing entitlement error. I've attempted to add the com.apple.token to my app's keychain-access-groups entitlements, but this does not resolve the issue. I have checked the entitlements in my built app, per the recommendation in the troubleshooting guide here: https://aninterestingwebsite.com/forums/thread/114456. The entitlement for com.apple.token is indeed present in the plist. Based on other documentation I've read, however, it seems that the explicit declaration of com.apple.token should not even be required in the entitlements. Is there something obvious that I'm missing here that would prevent my app from accessing the token access group?

I am developing a macOS application (targeting macOS 13 and later) that is non-sandboxed and needs to install and trust a root certificate by adding it to the System keychain programmatically. I’m fine with prompting the user for admin privileges or password, if needed. So far, I have attempted to execute the following command programmatically from both: A user-level process A root-level process sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain /path/to/cert.pem While the certificate does get installed, it does not appear as trusted in the Keychain Access app. One more point: The app is not distributed via MDM. App will be distributed out side the app store. Questions: What is the correct way to programmatically install and trust a root certificate in the System keychain? Does this require additional entitlements, signing, or profile configurations? Is it possible outside of MDM management? Any guidance or working samples would be greatly appreciated.

In the hopes of saving others time, the updated demo project (i.e. the new Shiny) can be found from the video 'Resources' section under 'Performing fast account creation with passkeys'. The beta documentation can also be found from there. All of the new functionality is available only on *OS 26 at this time.

Hi all, I’m building a macOS-native C++ trading bot, compiled via Xcode. It sends REST API requests to a crypto exchange (Bitvavo) that require HMAC-SHA256 signatures using a pre-sign string (timestamp + method + path + body) and an API secret. Here’s the issue: • The exact same pre-sign string and API secret produce valid responses when signed using Python (hmac.new(secret, msg, hashlib.sha256)), • But when I generate the HMAC signature using C++ (HMAC(EVP_sha256, ...) via OpenSSL), the exchange returns an invalid signature error. Environment: • Xcode 15.3 / macOS 14.x • OpenSSL installed via Homebrew • HMAC test vectors match Python’s output for basic strings (so HMAC lib seems correct) Yet when using the real API keys and dynamic timestamped messages, something differs enough to break verification — possibly due to UTF-8 encoding, memory alignment, or newline handling differences in the Xcode C++ runtime? Has anyone experienced subtle differences between Python and C++ HMAC-SHA256 behavior when compiled in Xcode? I’ve published a GitHub repo for reproducibility: 🔗 https://github.com/vanBaardewijk/bitvavo-cpp-signature-test Thanks in advance for any suggestions or insights. Sascha

I understand from the recent Apple Developer News that Korean developers are now required to register a URL to receive notifications from the Apple server when creating or modifying a Sign in With Apple Service ID. However, it is not clear whether simply registering the URL is sufficient, or if it is also mandatory to implement the real-time processing of those notifications. I am inquiring whether the processing part is also a mandatory requirement.

I have developed a sample app following the example found Updating your app package installer to use the new Service Management API and referring this discussion on XPC Security. The app is working fine, I have used Swift NSXPCConnection in favour of xpc_connection_create_mach_service used in the example. (I am running app directly from Xcode) I am trying to set up security requirements for the client connection using setCodeSigningRequirement on the connection instance. But it fails for even basic requirement connection.setCodeSigningRequirement("anchor apple"). Error is as follows. cannot open file at line 46986 of [554764a6e7] os_unix.c:46986: (0) open(/private/var/db/DetachedSignatures) - Undefined error: 0 xpc_support_check_token: anchor apple error: Error Domain=NSOSStatusErrorDomain Code=-67050 "(null)" status: -67050 I have used codesign -d --verbose=4 /path/to/executable to check the attributes I do get them in the terminal.

Q: Please advise is there some setting required to be enabled or I have to sign code with some flags enabled. Note: My app is not running in a Sandbox or Hardened Runtime, which I want.

Hi everyone, I’m working an Objective-C lib that performs Keychain operations, such as generating cryptographic keys and signing data. The lib will be used by my team in a Java program for macOS via JNI. When working with the traditional file-based Keychain (i.e., without access control flags), everything works smoothly, no issues at all. However, as soon as I try to generate a key using access control flags SecAccessControlCreateWithFlags, the Data Protection Keychain returns error -34018 (errSecMissingEntitlement) during SecKeyCreateRandomKey. This behavior is expected. To address this, I attempted to codesign my native dynamic library (.dylib) with an entitlement plist specifying various combinations of: keychain-access-groups com.apple.security.keychain etc. with: My Apple Development certificate Developer ID Application certificate Apple Distribution certificate None of these combinations made a difference, the error persists. I’d love to clarify: Is it supported to access Data Protection Keychain / Secure Enclave Keys in this type of use case? If so, what exact entitlements does macOS expect when calling SecKeyCreateRandomKey from a native library? I’d really appreciate any guidance or clarification. Thanks in advance! Best regards, Neil

Trying to apply 'always trust' to certificate added to keychain using both SecItemAdd() and SecPKCS12Import() with SecTrustSettingsSetTrustSettings(). I created a launchdaemon for this purpose. AuthorizationDB is modified so that any process running in root can apply trust to certificate. let option = SecTrustSettingsResult.trustRoot.rawValue // SecTrustSettingsResult.trustAsRoot.rawValue for non-root certificates let status = SecTrustSettingsSetTrustSettings(secCertificate, SecTrustSettingsDomain.admin, [kSecTrustSettingsResult: NSNumber(value: option.rawValue)] as CFTypeRef). Above code is used to trust certificates and it was working on os upto 14.7.4. In 14.7.5 SecTrustSettingsSetTrustSettings() returns errAuthorizationInteractionNotAllowed. In 15.5 modifying authorization db with AuthorizationRightSet() itself is returning errAuthorizationDenied.Tried manually editing authorization db via terminal and same error occurred. Did apple update anything on Security framework? Any other way to trust certificates?

Hi Team, How can we fetch the macOS password requirement(for setting a new password) that are inforce during login for users? Is there a way to get this info in swift programming?

My high-level goal is to add support for Game Mode in a Java game, which launches via a macOS "launcher" app that runs the actual java game as a separate process (e.g. using the java command line tool). I asked this over in the Graphics & Games section and was told this, which is why I'm reposting this here. I'm uncertain how to speak to CLI tools and Java games launched from a macOS app. These sound like security and sandboxing questions which we recommend you ask about in those sections of the forums. The system seems to decide whether to enable Game Mode based on values in the Info.plist (e.g. for LSApplicationCategoryType and GCSupportsGameMode). However, the child process can't seem to see these values. Is there a way to change that? (The rest of this post is copied from my other forums post to provide additional context.) Imagine a native macOS app that acts as a "launcher" for a Java game.** For example, the "launcher" app might use the Swift Process API or a similar method to run the java command line tool (lets assume the user has installed Java themselves) to run the game. I have seen How to Enable Game Mode. If the native launcher app's Info.plist has the following keys set: LSApplicationCategoryType set to public.app-category.games LSSupportsGameMode set to true (for macOS 26+) GCSupportsGameMode set to true The launcher itself can cause Game Mode to activate if the launcher is fullscreened. However, if the launcher opens a Java process that opens a window, then the Java window is fullscreened, Game Mode doesn't seem to activate. In this case activating Game Mode for the launcher itself is unnecessary, but you'd expect Game Mode to activate when the actual game in the Java window is fullscreened. Is there a way to get Game Mode to activate in the latter case? ** The concrete case I'm thinking of is a third-party Minecraft Java Edition launcher, but the issue can also be demonstrated in a sample project (FB13786152). It seems like the official Minecraft launcher is able to do this, though it's not clear how. (Is its bundle identifier hardcoded in the OS to allow for this? Changing a sample app's bundle identifier to be the same as the official Minecraft launcher gets the behavior I want, but obviously this is not a practical solution.)

For context, my company develops a data loss prevention (DLP) product. Part of our functionality is the ability to detect sensitive data being pasted into a web browser or cloud-based app. The AppKit release notes for April 2025 document an upcoming “macOS pasteboard privacy” feature, which will presumably ship in macOS 26. Using the user default setting “EnablePasteboardPrivacyDeveloperPreview” documented in the release notes, I tested our agent under macOS 15.5, and encountered a modal alert reading " is trying to access the pasteboard" almost immediately, when the program reads the General pasteboard to scan its contents. Since our product is aimed at enterprise customers (and not individual Mac users), I believed Apple would implement a privacy control setting for this new feature. This would allow our customers to push a configuration profile via MDM, with the “Paste from Other Apps” setting for our application preset to “Allow”, so that they can install our product on their endpoints without manual intervention. Unfortunately, as of macOS 26 beta 4 (25A5316i), there does not seem to be any such setting documented under Device Management — for example in PrivacyPreferencesPolicyControl.Services, which lists a number of similar settings. Without such a setting available, a valuable function of our product will be effectively crippled when macOS 26 is released. Is there such a setting (that I've overlooked)? If not, allow me to urge Apple to find the resources to implement one, so that our customers can preset “Paste from Other Apps” to “Allow” for our application.

Problem Description: In our App, When we launch the web login part using ASWebAuthentication + Universal Links with callback scheme as "https", we are not receiving callback. Note: We are using "SwiftUIWebAuthentication" Swift Package Manager to display page in ASWebAuth. But when we use custom url scheme instead of Universal link, app able to receive call back every time. We use ".onOpenURL" to receive universal link callback scheme.

Hello, I want to access the Docker socket API from inside the macOS App Sandbox. The method queries the API using curl with --unix-socket. However, the Sandbox blocks the request, as shown by the log: curl(22299) deny(1) network-outbound /Users/user/.docker/run/docker.sock Outgoing network traffic is generally allowed, but access to the Docker Unix socket is denied. Here’s the code I’m using: private func executeDockerAPI() -> String { let process = Process() let pipe = Pipe() process.executableURL = URL(fileURLWithPath: "/usr/bin/curl") process.arguments = [ "--unix-socket", "/Users/user/.docker/run/docker.sock", "http://127.0.0.1/containers/json" ] process.standardOutput = pipe process.standardError = pipe do { try process.run() process.waitUntilExit() let data = pipe.fileHandleForReading.readDataToEndOfFile() if let output = String(data: data, encoding: .utf8) { return output } else { return "Error while decoding" } } catch { return "Error running command: \(error.localizedDescription)" } } Is there any entitlement or sandbox configuration I’m missing to allow access to /Users/user/.docker/run/docker.sock from inside the sandbox?

Hi there, I'm trying to use SFAuthorizationPluginView in order to show some fields in the login screen, have the user click the arrow, then continue to show more fields as a second step of authentication. How can I accomplish this? Register multiple SecurityAgentPlugins each with their own mechanism and nib? Some how get MacOS to call my SFAuthorizationPluginView::view() and return a new view? Manually remove text boxes and put in new ones when button is pressed I don't believe 1 works, for the second mechanism ended up calling the first mechanism's view's view() Cheers, -Ken

I have been implementing an sdk for authenticating a user. I have noticed that on iOS 18.5, whether using SFSafariViewController, or the sdk (built on ASWebAuthenticationSession), password autofill does not work. I have confirmed it works on a different device running iOS 18.0.1. Are there any work arounds for this at this time? Specifically for ASWebAuthenticationSession?
