We have a custom SecurityAgentPlugin that is triggered by multiple authorizationdb entries. Some customers report that the SecurityAgent process takes window focus even though no UI or windows are displayed. Our plugin explicitly ignores the _securityAgent user and does not show any UI for that user. However, in macOS 26.1, it appears that the plugin still causes the SecurityAgent to take focus as soon as it is triggered. Is this a change in macOS 26.1 or a bug? Can we do anything to prevent "focus stealing"?

I'm experiencing a strange issue where ASWebAuthenticationSession works perfectly when running from Xcode (both Debug and Release), but fails on TestFlight builds. The setup: iOS app using ASWebAuthenticationSession for OIDC login (Keycloak) Custom URL scheme callback (myapp://) prefersEphemeralWebBrowserSession = false The issue: When using iOS Keychain autofill (with Face ID/Touch ID or normal iphone pw, that auto-submits the form) -> works perfectly When manually typing credentials and clicking the login button -> fails with white screen When it fails, the form POST from Keycloak back to my server (/signin-oidc) never reaches the server at all. The authentication session just shows a white screen. Reproduced on: Multiple devices (iPhone 15 Pro, etc.) iOS 18.x Xcode 16.x Multiple TestFlight testers confirmed same behavior What I've tried: Clearing Safari cookies/data prefersEphemeralWebBrowserSession = true and false Different SameSite cookie policies on server Verified custom URL scheme is registered and works (testing myapp://test in Safari opens the app) Why custom URL scheme instead of Universal Links: We couldn't get Universal Links to trigger from a js redirect (window.location.href) within ASWebAuthenticationSession. Only custom URL schemes seemed to be intercepted. If there's a way to make Universal Links work in this context, without a manual user-interaction we'd be happy to try. iOS Keychain autofill works The only working path is iOS Keychain autofill that requires iphone-authentication and auto-submits the form. Any manual form submission fails, but only on TestFlight - not Xcode builds. Has anyone encountered this or know a workaround?

Hi everyone, I'm currently working on a native macOS app (built with SwiftUI) and I'm trying to implement Password AutoFill functionality so users can use their saved credentials from Keychain or third-party password managers. I've gone through Apple's documentation, WWDC sessions, and sample code, but I've noticed that the resources primarily focus on iOS and web implementations. There's very limited guidance specifically for macOS. I've set up: Associated Domains entitlement with the webcredentials: service The apple-app-site-association file on my server TextField with .textContentType(.username) and SecureField with .textContentType(.password) However, I'm still not seeing the expected AutoFill behavior on macOS like I would on iOS. Has anyone successfully implemented Password AutoFill on a native macOS app? Are there any macOS-specific considerations or additional steps required that differ from iOS? Any guidance, sample code, or pointers to documentation I might have missed would be greatly appreciated.

Hello Team, We’ve recently started receiving reports from our customer base (Trellix) regarding issues with Full Disk Access (FDA) for Trellix binaries on macOS devices running Tahoe 26.1 (released on November 3, 2025). The issue occurs when users attempt to add Trellix CLI binaries under FDA to grant the required permissions; the binaries fail to appear under the FDA settings, even after selection. Upon further investigation, this appears to be a macOS 26.1–specific issue and not observed in earlier versions. Similar reports have been noted across various forums, indicating that the issue affects multiple binaries, not just Trellix: Some of the discussions on the same issue I see online. https://developer.apple.com/forums/thread/806187 https://developer.apple.com/forums/thread/806156 https://forum.logik.tv/t/macos-26-1-installation-issue-wait-before-updating/13761 https://www.reddit.com/r/MacOS/comments/1os1ph3/cant_add_anything_to_privacy_security_full_disk/ I have also logged FB21009024 for the same. We would like to understand when we can expect this to be fixed, since the issue persists even in 26.2 Beta and also whether the workaround of dragging and dropping the binaries can still be suggested?

Hi, After enabling the new Enhanced Security capability in Xcode 26, I’m seeing install failures on devices running < iOS 26. Deployment target: iOS 15.0 Capability: Enhanced Security (added via Signing & Capabilities tab) Building to iOS 18 device error - Unable to Install ...Please ensure sure that your app is signed by a valid provisioning profile. It works fine on iOS 26 devices. I’d like to confirm Apple’s intent here: Is this capability formally supported only on iOS 26 and later, and therefore incompatible with earlier OS versions? Or should older systems ignore the entitlement, meaning this behavior might be a bug?

While working with Platform SSO on macOS, I’m trying to better understand how the system handles cases where a user’s local account password becomes unsynchronized with their Identity Provider (IdP) password—for example, when the device is offline during a password change. My assumption is that macOS may store some form of persistent token during the Platform SSO user registration process (such as a certificate or similar credential), and that this token could allow the system to unlock the user’s login keychain even if the local password no longer matches the IdP password. I’m hoping to get clarification on the following: Does macOS actually use a persistent token to unlock the login keychain when the local account password is out of sync with the IdP password? If so, how is that mechanism designed to work? If such a capability exists, is it something developers can leverage to enable a true passwordless authentication experience at the login window and lock screen (i.e., avoiding the need for a local password fallback)? I’m trying to confirm what macOS officially supports so I can understand whether passwordless login is achievable using the persistent-token approach. Thanks in advance for any clarification.

From watching the video on App Attest the answer would appear to be no, but the video is a few years old so in hope, I thought I would post this question anyway. There's several scenarios where I would like a notification service extension to be able to use App Attest in communications with the back end(for example to send a receipt to the backend acknowledging receipt of the push, fetching an image from a url in the push payload, a few others). Any change App Attest can be used in by a notification service extension?

Hi... It would be nice if Apple / XCode would be so gracious to explore the possibility of providing the ability to include: Code scrambling / renaming Control-flow obfuscation String encryption Anti-debugging Anti-hooking Jailbreak detection App integrity checks Runtime tamper detection That way, we could eliminate the need to settle for third-party software. Who do we have to bribe to submit such a request and entertain such an idea?

I noticed, that even though my AutoFill Credential Provider Extension works with Safari for both Passwords and Passkeys, it doesn't work in context menus inside arbitrary textfields, meanwhile the same is true for the Apple Passwords app. This is a great hit to AutoFill productivity, as my extension is unable to fill textfields by just going to the context menu and clicking AutoFill > Passwords.. Is this a feature only available to Apple via private APIs, or is this something I can interface with? I checked and the Passwords app does use some undocumented but non-private entitlements: [Key] com.apple.authentication-services.access-credential-identities [Value] [Bool] true I also checked the responsible executable for some hints (AutoFillPanelService) however found nothing that would lead me to believe this is a public extension point. Another idea I had was trying to use a macOS Service for this, however Services in the "General" category won't show up in any context menu, only in the Application's Main Menu.

When trying to check if a certificate has been revoked with SecPolicyCreateRevocation (Flags: kSecRevocationUseAnyAvailableMethod | kSecRevocationRequirePositiveResponse) and SecTrustEvaluateWithError I always get the result error code errSecIncompleteCertRevocationCheck, regardless if the certificate was revoked or not. Reproduction: Execute the program from the attached Xcode project (See Feedback FB21224106). Error output: Error: Error Domain=NSOSStatusErrorDomain Code=-67635 ""revoked.badssl.com","E8","ISRG Root X1" certificates do not meet pinning requirements" UserInfo={NSLocalizedDescription="revoked.badssl.com","E8","ISRG Root X1" certificates do not meet pinning requirements, NSUnderlyingError=0x6000018d48a0 {Error Domain=NSOSStatusErrorDomain Code=-67635 "Certificate 0 “revoked.badssl.com” has errors: Failed to check revocation;" UserInfo={NSLocalizedDescription=Certificate 0 “revoked.badssl.com” has errors: Failed to check revocation;}}} To me it looks like that the revocation check just fails („Failed to check revocation;“), no further information is provided by the returned error. In the example the certificate chain of https://revoked.badssl.com (default code) and https://badssl.com is verified (to switch see comments in the code). I have a proxy configured in the system, I assume that the revocation check will use it. On the same machine, the browsers (Safari and Google Chrome) can successfully detect if the certificate was revoked (revoked.badssl.com) or not (badssl.com) without further changes in the system/proxy settings. Note: The example leaks some memory, it’s just a test program. Am I missing something? Feedback: FB21224106

Since October 3rd, I've stopped receiving responses to the Private Access Tokens challenge. I'm using this link: https://demo-issuer.private-access-tokens.fastly.com/.well-known/token-issuer-directory. I receive tokens from Fastly and return a header to the iOS app, but then I don't receive another authentication request from iOS. The user has automatic verification enabled on their phone. The problem is global and affects all my mobile app users. Has anyone encountered a similar problem and found a solution?

I read online that there is no way to extract the call log from an iPhone. I want to develop an app to help people remember to call their mom, and if they did, the "nagging" would disappear automatically. I'm looking for any workaround to know when a user called someone, without having them log it manually.

We're experiencing crashes in our production iOS app related to Apple's DeviceCheck framework. The crash occurs in DCAnalytics internal performance tracking, affecting some specific versions of iOS 18 (18.4.1, 18.5.0). Crash Signature CoreFoundation: -[__NSDictionaryM setObject:forKeyedSubscript:] + 460 DeviceCheck: -[DCAnalytics sendPerformanceForCategory:eventType:] + 236 Observed Patterns Scenario 1 - Token Generation: Crashed: com.appQueue EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000010 DeviceCheck: -[DCDevice generateTokenWithCompletionHandler:] Thread: Background dispatch queue Scenario 2 - Support Check: Crashed: com.apple.main-thread EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000008 DeviceCheck: -[DCDevice _isSupportedReturningError:] DeviceCheck: -[DCDevice isSupported] Thread: Main thread Root Cause Analysis The DCAnalytics component within DeviceCheck attempts to insert a nil value into an NSMutableDictionary when recording performance metrics, indicating missing nil validation before dictionary operations. Reproduction Context Crashes occur during standard DeviceCheck API usage: Calling DCDevice.isSupported property Calling DCDevice.generateToken(completionHandler:) (triggered by Firebase App Check SDK) Both operations invoke internal analytics that fail with nil insertion attempts. Concurrency Considerations We've implemented sequential access guards around DeviceCheck token generation to prevent race conditions, yet crashes persist. This suggests the issue likely originates within the DeviceCheck framework's internal implementation rather than concurrent access from our application code. Note: Scenario 2 occurs through Firebase SDK's App Check integration, which internally uses DeviceCheck for attestation. Request Can Apple engineering confirm if this is a known issue with DeviceCheck's analytics subsystem? Is there a recommended workaround to disable DCAnalytics or ensure thread-safe DeviceCheck API usage? Any guidance on preventing these crashes would be appreciated.

Hi, I’ve added attestation to my app, and everything worked as expected during setup. However, after deployment, I noticed some unknownSystemFailure entries in the production logs on New Relic. Could you help me understand what typically causes this error? The documentation suggests issues such as failing to generate a token. What scenarios could lead to that?

I have reached out to support and they simply tell me they are unable to help me, first redirecting me to generic Apple support, after following up they provided the explanation that they only handle administrative tasks and to post on the forums. I am unable to change my App Tracking Transparency it provides no real error, though network traffic shows a 409 HTTP response from the backend API when trying to save. Here is a screenshot of the result when trying to save. Does anyone have any suggestions on how to get this resolved? I've commented back to the reviewers and they simply provided help documentation. I have a technical issue and am unable to get anyone to help resolve this.

Hi Apple, Currently we want to have enhancement for SMS OTP that we want to implement OTP Autofill, But after do some research we're stuck with option that the OTP only show in keyboard suggestion, is there any way for making OTP is automatically filled without user have to click the keyboard suggestion when receiving the SMS. Thanks Best Regards, Admiral Sultano Harly.

Hi. I enter a password using the security command at the command line. It appears in the keychain access app, but not in the passwords app. I don't understand why. rickhedin@Ricks-MacBook-Pro zalando % security add-generic-password -U -s "birds" -a "cats" -w "dogs" rickhedin@Ricks-MacBook-Pro zalando % rickhedin@Ricks-MacBook-Pro zalando % security find-generic-password -s "birds" -wa "cats" dogs rickhedin@Ricks-MacBook-Pro zalando % I'm told the two apps are two views of the same data, so I guess some filter must be being applied?

Recently, we have adapted the passkey function on the Mac, but we always encounter the error message "Unable to verify the web credentials association of xxx with domain aaa. Please try again in a few seconds." We can confirm that https://aaa/.well-known/apple-app-site-association has been configured and is accessible over the public network. Additionally, the entitlements in the app have also been set with webcredentials:aaa. This feature has been experiencing inconsistent performance. When I restart my computer or reinstall the pkg, this feature may work or it may still not work. I believe this is a system issue. Here is feed back ID: FB20876945 In the feedback, I provided the relevant logs. If you have any suggestions or assistance, please contact me. I would be extremely grateful!

Hello, When using ASWebAuthenticationSession with an HTTPS callback URL (Universal Link), I receive the following error: Authorization error: The operation couldn't be completed. Application with identifier jp.xxxx.yyyy.dev is not associated with domain xxxx-example.go.link. Using HTTPS callbacks requires Associated Domains using the webcredentials service type for xxxx-example.go.link. I checked Apple’s official documentation but couldn’t find any clear statement that webcredentials is required when using HTTPS callbacks in ASWebAuthenticationSession. What I’d like to confirm: Is webcredentials officially required when using HTTPS as a callback URL with ASWebAuthenticationSession? If so, is there any official documentation or technical note that states this requirement? Environment iOS 18.6.2 Xcode 16.4 Any clarification or official references would be greatly appreciated. Thank you.
