Hello, I am developing a macOS menu bar window-management utility (similar in functionality to Magnet / Rectangle) that relies on the Accessibility (AXUIElement) API to move and resize windows and on global hotkeys. I am facing a consistent issue when App Sandbox is enabled. Summary: App Sandbox enabled Hardened Runtime enabled Apple Events entitlement enabled NSAccessibilityDescription present in Info.plist AXIsProcessTrustedWithOptions is called with prompt enabled Observed behavior: When App Sandbox is enabled, the Accessibility permission prompt never appears. The app cannot be manually added in System Settings → Privacy & Security → Accessibility. AXIsProcessTrusted always returns false. As a result, window snapping does not work. When App Sandbox is disabled: The Accessibility prompt appears correctly. The app functions as expected. This behavior occurs both: In local builds In TestFlight builds My questions: Is this expected behavior for sandboxed macOS apps that rely on Accessibility APIs? Are window-management utilities expected to ship without App Sandbox enabled? Is there any supported entitlement or configuration that allows a sandboxed app to request Accessibility permission? Thank you for any clarification.

Hi, I know it's been discussed before, but I'm testing the Sign in with Apple feature, and I only get the user info on the first try. Now, I know that you're supposed to go to the account settings, and look for the list of accounts that you used your Apple account to sign in with, and it used to work a few months back. But for the last few weeks I haven't been able to get the user info, even after deleting the entry from my Sign In With Apple app list. Has there been a recent change to Apple security policy that prevents such a move from working ? Or am I doing something wrong ? Thank you

With the new ios 26 update, certain numbers will be filtered into other inboxes within imessage. What numbers are classified as "known", and will not be moved into these filters. Do they need to be a contact in your phone, or if a business texts you how will that be filtered?

Our company developed an app that relies on the collected list to display the phone's label in the list when the user's phone receives an incoming call. However, we have been rejected. The main reason for the rejection is as follows: “ Guideline 1.1.6 - Safety - Objectionable Content The app still allows users to unblock and reveal blocked incoming numbers to identify the individual calling or texting, which is not appropriate. Specifically, your app claims to offer the call blocking functionality, but solely identifies numbers that the user has explicitly blocked themselves. Since users can choose to hide their caller ID in iPhone Settings, apps should not attempt to circumvent this iOS feature to reveal the caller's number. ” But our developers clearly stated that there is no way to bypass these settings, and CallDirectory Extensionde cannot directly "unlock hidden numbers" or bypass the built-in restrictions of IOS. We don't know how to solve this problem next, and hope to get everyone's help.

I have configured DKIM and amazon's default spf. but can't get emails using Amazon Send, do I have to configure a custom domain name here for this to work, I'd like to get a definitive conclusion!

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.

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.

Hi, I am developing a Platform SSO in order to have integrated with our IdP, which I am also adapting to provide the right endpoints for Platform SSO. I have a few questions about the implementation: does the client-request-id need to be present on all requests? Is it unique per request, or requests that are bound together like those requesting a nonce and those who will use that nonce should use the same client-request-id? I am not sure how the loginManager.presentRegistrationViewController works. I'd like to get the user to authenticate to my IdP before device registration. So I am not sure if I should provide my own Webview or something similar or if this method should do something for me; My idea is to request user authentication once, save the state when performing device registration, so that I avoid asking for user authentication twice when performing user registration. Is this the right way to do it? How does platform SSO handles tokens? If one application of my IdP requests the authentication on a common OIDC/OAuth2 flow, should I perform some sort of token exchange? How about SAML? Platform SSO seems to be token-centric, but how does one handle SAML flows? Is it by using WebView as well?

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, I’m currently implementing App Attest attestation validation on the development server. However, I’m receiving a 403 Forbidden response when I POST a CBOR-encoded payload to the following endpoint: curl -X POST -H "Content-Type: application/cbor" --data-binary @payload.cbor 'https://data-development.appattest.apple.com' Here’s how I’m generating the CBOR payload in Java: Map<String, Object> payload = new HashMap<>(); payload.put("attestation", attestationBytes); // byte[] from DCAppAttestService payload.put("clientDataHash", clientDataHash); // SHA-256 hash of the challenge (byte[]) payload.put("keyId", keyIdBytes); // Base64-decoded keyId (byte[]) payload.put("appId", TEAM_ID + "." + BUNDLE_ID); // e.g., "ABCDE12345.com.example.app" ObjectMapper cborMapper = new ObjectMapper(new CBORFactory()); byte[] cborBody = cborMapper.writeValueAsBytes(payload); I’m unsure whether the endpoint is rejecting the payload format or if the endpoint itself is incorrect for this stage. I’d appreciate clarification on the following: 1. Is https://data-development.appattest.apple.com the correct endpoint for key attestation in a development environment? 2. Should this endpoint accept CBOR-encoded payloads, or is it only for JSON-based assertion validation? 3. Is there a current official Apple documentation that lists: • the correct URLs for key attestation and assertion validation (production and development), • or any server-side example code (e.g., Java, Python) for handling attestation/validation on the backend? So far, I couldn’t find an official document that explicitly describes the expected HTTP endpoints for these operations. If there’s a newer guide or updated API reference, I’d appreciate a link. Thanks in advance for your help.

Hey everyone, I'm hitting a really frustrating issue with App Attest. My app was working perfectly with DCAppAttestService on October 12th, but starting October 13th it started failing with DCError Code 2 "Failed to fetch App UUID" at DCAppAttestController.m:153. The weird part is I didn't change any code - same implementation, same device, same everything. I've tried switching between development and production entitlement modes, re-registered my device in the Developer Portal, created fresh provisioning profiles with App Attest capability, and verified that my App ID has App Attest enabled. DCAppAttestService.isSupported returns true, so the device supports it. Has anyone else run into this? This is blocking my production launch and I'm not sure if it's something on my end or an Apple infrastructure issue.

AFAIU a new screen capture notification was added within the Control Center in Sequoia 15.2, see attached examples: My question is whether there is some way to suppress this notification preferably via an MDM configuration profile. See also https://discussions.apple.com/thread/255886645?sortBy=rank for more information. Thanks, Doron.

When I delete an image from my camera roll, my iPhone adds another previously deleted image to my camera roll. This previously deleted image or video is from up to 3 years ago, and isn't in my recently deleted. Therefore, these added images should technically not exist. I am using an iPhone 12 running iOS 26 public beta, but apparently this issue is happening on iOS 18 too. I feel worried that an image/video that I deleted for privacy reasons may appear back in my camera roll. I'll add that I am paying for iCloud+ storage, and I still have 15GB of local storage left on my device.

I've come across strange behavior with the userID property on the returned credential from a passkey attestation. When performing a cross-device passkey assertion between iOS and Android by scanning the generated QR code on my iPhone with an Android device the returned credential object contains an empty userID. This does not happen when performing an on device or cross-device assertion using two iPhones. Is this expected behavior, or is there something I'm missing here? I couldn't find any more information on this in the documentation. iOS Version: 26.0.1, Android Version: 13

I keep getting the following error when trying to run Passkey sign in on macOS. Told not to present authorization sheet: Error Domain=com.apple.AuthenticationServicesCore.AuthorizationError Code=1 "(null)" ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "(null)" This is the specific error. Application with identifier a is not associated with domain b I have config the apple-app-site-association link and use ?mode=developer Could there be any reason for this?

We are developing an app that uses Authentication Services to authenticate users. According to the documentation, this framework will open the default web browser if it supports auth session handling, and Safari otherwise. This is not entirely true, and users will be frustrated! macOS version: Sequoia 15.5; Safari version: 18.5. When: The default browser is not Safari, and supports auth session handling (Google Chrome and Microsoft Edge as examples); and - The Safari app is already running; The auth flow will: Present the confirmation dialog box with the default browser icon. Good! Open a Safari window, instead of the default browser's one. Bad! Respond with "User Cancelled" error to the app, after making the end user believe the auth was good. Very Bad!! If the app retries the auth session, the default browser window will open as expected, and it will work as expected. However, requiring users to authenticate twice is a very bad users experience... This issue does not reproduce, when either: Safari is not running at the moment of auth session start; The default browser does not support auth session handling; or - Safari is the default browser. Fellow developers, be warned! Apple engineers, feedback #18426939 is waiting for you. Cheers!

Hi. We are trying to get the access token before calling any API. The app can go in bad network areas but the token acquisition keeps happening for the network call. The devices are managed devices which means it has some policies installed. We are using MSAL lib for the authentication and we are investigating from that angle too but the below error seems to be coming from apple authentication which needs our attention. ========================================== LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=68, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Attempt to map database failed: permission was denied. This attempt will not be retried. Failed to initialize client context with error Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=68, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Failed to get application extension record: Error Domain=NSOSStatusErrorDomain Code=-54 "(null)" ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1003 "(null)" ========================================== This happens mostly when we switches the network or keep the device in no or low network area. This comes sometimes when app goes in background too. Just trying to give as much as information I could. Any lead would be highly appreciated. Thank you

I am currently working on Fraud System Detection that will be used by one of the financial institutions. Those tools are related to ensuring user security. Our goal is to identify features that can trigger an early warning system for attempted fraud. We have identified three uncertain variables: Whether the user is having a conversation while using our app, Whether the user has specific screen sharing apps on their phone, Whether the user has enabled VPN connection. Here my doubts appear: Can we check the presence of a telephone conversation if we are not a VOIP application? Can we check the presence of installed programs using Universal Link and canOpenUrl(_:) method? Can we read "SCOPED" key from CFNetworkCopySystemProxySettings() dictionary? I will be glad for any advice and help.

We are using SecPKCS12Import C API in our application to import a self seigned public key certificate. We tried to run the application for the first time on Tahoe and it failed with OSStatus -26275 error. The release notes didn't mention any deprecation or change in the API as per https://developer.apple.com/documentation/macos-release-notes/macos-26-release-notes. Are we missing anything? There are no other changes done to our application.

I'm looking for confirmation on the security aspects of fdesetup authrestart when used on a FileVault-enabled Mac. As I understand it, this command temporarily stores the decryption key in memory to allow the system to restart without requiring manual entry of the FileVault password. However, I have a few security-related concerns: Storage of the Decryption Key: Where exactly is the key stored during an authenticated restart? Is it protected within the Secure Enclave (for Apple Silicon Macs) or the T2 Security Chip on Intel Macs? Key Lifetime & Wiping: At what point is the decryption key erased from memory? Does it persist in any form after the system has fully rebooted? Protection Against Physical Attacks: If an attacker gains physical access to the machine before the restart completes, is there any possibility that they could extract the decryption key from memory? Cold Boot Attack Resistance: Is there any risk that advanced forensic techniques (such as freezing RAM to retain data) could be used to recover the decryption key after issuing an authenticated restart? Malware Resistance: Could a compromised system (e.g., root access by an attacker) intercept or misuse the decryption key before the restart? I understand that on Apple Silicon and T2-equipped Macs, FileVault keys are tied to hardware-based encryption, making unauthorized access difficult. However, I'd like to confirm whether Authenticated Restart introduces any new risks compared to a standard FileVault-enabled boot process.
