Hi, I have a certificate, how can I display the certificate content in my Mac app just like Keychain Access app does. Can I popup the certificate content dialog just like Keychain Access app?

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, ASCredentialProvider had been almost identically implemented on both iOS and macOS so far, but the ProvidesTextToInsert feature was only added to iOS. It would have been a crucial point to make Credential Providers available in all textfields, without users having to rely on developers correctly setting roles for their Text Fields. It's right now impossible to paste credentials into Notes, or some other non-password text box both in web and desktop apps for example, in a seamless, OS-supported way without abusing Accessibility APIs which are understandably disallowed in Mac App Store apps. Or just pasting an SSH key, or anything. On macOS this has so many possibilities. It could even have a terminal command. It's even more interesting that "Passwords..." is an option in macOS's AutoFill context menu, just like on iOS, however Credential Providers did not gain this feature on macOS, only on iOS. Is this an upcoming feature, or should we find alternatives? Or should I file a feature request? If it's already in the works, it's pointless to file it.

转让app成功了之后，由于开发者账号更改，团队ID改变，导致获取不到原有的keychain中缓存的用户数据，所以在用户进行登录时，无法登录到原有的老账号，而是被识别成了一个新的用户。这种情况怎么解决。

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!

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.)

I am developing a MacOS Authorisation Plugin, I have username and password entry items and utilising SFAuthorizationPluginView to display that. I am able to do so. Requirement is I have to store ed25519 private key in PEM format in System Keychain as I need to read this entry before login to sign a request to a remote server. I only want my authorisation plugin to access this private key in System Keychain. I am looking up resources on the internet but I could not find specific to macOS Authorisation plugin, many are specific to iOS and some point at using entitlements and app group, but I doubt that applies to macOS authorisation plugin. I'll really appreciate if some pointers are shared how can I store a private credential in System Keychain so that it can be used by only my plugin only, and this is before I have logged into the system.

I have a custom NSWindow that I want to exclude from screen capture by setting its sharing state to kCGWindowSharingStateSharingNone. The goal is to prevent this window from appearing in the content captured by ScreenCaptureKit. [window setSharingType:NSWindowSharingType::NSWindowSharingNone]; However, on macOS 15.4+ (Sequoia), the window is still captured by ScreenCaptureKit and appears in the shared content. Does anyone know if kCGWindowSharingStateSharingNone is still effective with ScreenCaptureKit on macOS 15.4 and later?

Hi Forum, We’re building a security-focused SDK for iOS that includes SIM Binding and SIM Swap detection to help prevent fraud and unauthorised device access, particularly in the context of banking and fintech apps. We understand that iOS limits access to SIM-level data, and that previously available APIs (such as those in CoreTelephony, now deprecated from iOS 16 onwards) provide only limited support for these use cases. We have a few questions and would appreciate any guidance from the community or Apple engineers: Q1. Are there any best practices or Apple-recommended approaches for binding a SIM to a device or user account? Q2. Is there a reliable way to detect a SIM swap when the app is not running (e.g., via system callback, entitlement, or background mechanism)? Q3. Are fields like GID1, GID2, or ICCID accessible through any public APIs or entitlements (such as com.apple.coretelephony.IdentityAccess)? If so, what is the process to request access? Q4. For dual SIM and eSIM scenarios, is there a documented approach to identify which SIM is active or whether a SIM slot has changed? Q5. In a banking or regulated environment, is it possible for an app vendor (e.g., a bank) to acquire certain entitlements from Apple and securely expose that information to a security SDK like ours? What would be the compliant or recommended way to structure such a partnership? Thanks in advance for any insights!

Hi, We are using the following API from sys/random.h to generate entropy in our module. int getentropy(void* buffer, size_t size); Could you confirm if this API internally uses a non-physical entropy source and adhere to SP800-90B as the following document says: https://csrc.nist.gov/CSRC/media/projects/cryptographic-module-validation-program/documents/entropy/E181_PublicUse.pdf

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. We're writing Authorization Plugin and started with NullAuthPlugin compilation. When tried to run it on VM (Sonoma 14.6, SIP enabled), we're going into the following issue: `2025-03-08 13:38:20.699503-0800 0xdcb0 Error 0x0 0 0 kernel: (AppleMobileFileIntegrity) [com.apple.MobileFileIntegrity:library_validation_failure] Library Validation failed: Rejecting '/Library/Security/SecurityAgentPlugins/NullAuthPlugin.bundle/Contents/MacOS/NullAuthPlugin' (Team ID: ABCD12EF34, platform: no) for process 'SecurityAgentHel(2094)' (Team ID: N/A, platform: yes), reason: mapping process is a platform binary, but mapped file is not' As I understand, the platform binary is the one signed with Apple signature, which indeed is unavailable for us. How can we avoid this issue and run the plugin? Perhaps we're missing some build setting requirement?

I want iOS device identifier for a framework that is used in multiple vendor's apps. I'm developing a framework to control a peripheral. The framework has to send unique information to register the device with the peripheral. My naive idea was to use IdentifierForVendor. But this API provides the device identifier for the same vendor's apps, not the framework. (The framework will be used by multiple vendors.) Is there a usable device identifier for the framework, regardless of app vendor? Please tell me any solution.

Hi, I am working on Authorisation Plugin for Mac OS X and able to get going for most of the parts and taking inspiration from Jamf Authorisation Plugin repo https://github.com/jamf/NoMADLogin-AD. I have seen in project they are implementing logic for following. Connecting to Wifi Power management (Sleep, Restart, Power Off) Question: I was wondering these things need to be implemented or is there a way some components from Mac OS X could be integrated calling some API and I don't have to implement them and I see say a top bar where these items are viable as we see in default login screen. I have developed my own login screen and I do see it is all blank everything I have to implement from scratch. Trying luck here if any API is out there to reduce work, else no option but to implement all logic. I'll really appreciate if someone just could help me know such API's are present or not. In case there are will save lot of effort. Thanks,

I had the following code in a program that I used to encrypt some important files. I haven't run it in a few years. It used to work, and now it seems the password is mysteriously gone from my Keychain! The return value is now errSecItemNotFound. I'm upset with myself for not backing up the key/password somewhere else. Is there anywhere this could be hiding? Did Apple move it somewhere? I know they created this "Passwords" app in recent years, but I don't see anything in there with the "account" string I used. I run the app from Xcode, so maybe it is in the "container" data somewhere? I do see keychain files under ~/Library. Maybe there is a way to look through old Time Machine backups. Ug. So stressful. Just looking for pointers on where the data might be, and why it might have disappeared. Unfortunately it was not a "guessable" password, it was a generated 256 bit key, base64 encoded. Perhaps I could crack that with brute force if I'm determined enough... public static func queryGenericPasswordAsString(account: String) throws -> String { let query: [String: Any] = [kSecClass as String: kSecClassGenericPassword, kSecMatchLimit as String: kSecMatchLimitOne, kSecAttrAccount as String: account, kSecReturnAttributes as String: true, kSecReturnData as String: true] var item: CFTypeRef? let status = SecItemCopyMatching(query as CFDictionary, &item) guard status != errSecItemNotFound else { throw KeychainError.noPassword } ... }

Hi, I am developing an app that checks if biometric authentication capabilities (Face ID and Touch ID) are available on a device. I have a few questions: Do I need to include a privacy string in my app to use the LAContext's canEvaluatePolicy function? This function checks if biometric authentication is available on the device, but does not actually trigger the authentication. From my testing, it seems like a privacy declaration is only required when using LAContext's evaluatePolicy function, which would trigger the biometric authentication. Can you confirm if this is the expected behavior across all iOS versions and iPhone models? When exactly does the biometric authentication permission pop-up appear for users - is it when calling canEvaluatePolicy or evaluatePolicy? I want to ensure my users have a seamless experience. Please let me know if you have any insights on these questions. I want to make sure I'm handling the biometric authentication functionality correctly in my app. Thank you!

I’m implementing a custom Authorization right with the following rule: <key>authenticate-user</key> <true/> <key>allow-root</key> <true/> <key>class</key> <string>user</string> <key>group</key> <string>admin</string> The currently logged-in user is a standard user, and I’ve created a hidden admin account, e.g. _hiddenadmin, which has UID≠0 but belongs to the admin group. From my Authorization Plug-in, I would like to programmatically satisfy this right using _hiddenadmin’s credentials, even though _hiddenadmin is not the logged-in user. My question: Is there a way to programmatically satisfy an authenticate-user right from an Authorization Plug-in using credentials of another (non-session) user?

Hi everyone, I'm looking for a way to configure Passkey on iOS so that authentication is only possible using FaceID or TouchID. Specifically, I want to disable the use of passcodes and QR codes for authentication. Additionally, is there a method to detect if the authentication was done using a passcode or QR code? Thanks for your help!

Hi, how can you authenticate a User through Biometrics with iPhone Passcode as Fallback in the Autofill Credential Provider Extension? In the App it works without a problem. In the Extension I get "Caller is not running foreground" Yeah, it isn't, as it's just a sheet above e.g. Safari. I'd like to avoid having the user setup a Passcode dedicated to my App, especially because FaceID is way faster. Does anybody know how to achieve iOS native Auth in the extension? Please let me know, a code sample would be appreciated. Regards, Mia

Hi, I was testing the lockdown mode in iOS 16 and would like to know whether we can detect the lockdown mode status using any public API that Apple provides. I really appreciate any help you can provide.
