It seems it is not possible to give a CLI app (non .app bundle) full disk access in macOS 26.1. This seems like a bug and if not that is a breaking change. Anybody seeing the same problem? Our application needs full disk access for a service running as a LaunchDaemon. The binary is located in a /Library subfolder.

QuickLookAR shares the actual USDZ model instead of the original website URL — critical copyright and data leak issue on iOS 26 Since iOS 26, QuickLookAR (or ARQuickLookPreviewItem) no longer preserves the original web URL when sharing a model. Instead of sending the link to the hosted file, the system directly shares the actual USDZ model file with the recipient. This is a critical regression and a severe breach of intellectual property protection, as it exposes proprietary 3D models that must never be distributed outside of the controlled web environment. In earlier iOS versions (tested up to iOS 18), QuickLookAR correctly handled sharing — the share sheet would send the website link where the model is hosted, not the file itself. Starting with iOS 26, this behavior has changed and completely breaks the intended secure flow for AR experiences. Our project relies on allowing users to view models in AR via QuickLook, without ever transferring the underlying 3D assets. Now, the share operation forces full file sharing, giving end users unrestricted access to the model file, which can be copied, rehosted, or reverse-engineered. This issue critically affects production environments and prevents us from deploying our AR-based solutions. Implement a standard QuickLookAR preview with a USDZ file hosted on your web server (e.g., via ARQuickLookPreviewItem). 2. Open the AR view on iOS 26. 3. Tap the Share icon from QuickLookAR. 4. Send via any messenger (Telegram, WhatsApp, etc.). 5. Observe that the actual .usdz model is sent instead of the original website URL. ⸻ Expected behavior: QuickLookAR should share only the original URL (as in iOS 17–18), not the file itself. This ensures that intellectual property and licensed 3D models remain protected and controlled by the content owner. ⸻ Actual behavior: QuickLookAR shares the entire USDZ file, leaking the model content outside of the intended environment. ⸻ Impact: • Violation of copyright and confidential data policies • Loss of control over proprietary 3D assets • Breaking change for all existing web-based AR integrations • Critical blocker for AR production deployment ⸻ Environment: • iOS 26.0 and 26.1 (tested on iPhone 14, iPhone 15) • Safari + QuickLookAR integration • Works correctly on iOS 17 / iOS 18 ⸻ Notes: This regression appears to have been introduced in the latest iOS 26 system handling of QuickLookAR sharing. Please escalate this issue to the ARKit / QuickLook engineering team as it directly affects compliance, IP protection, and usability of AR features across production applications. Additional Notes / Verification: Please test this behavior yourself using the CheckAR test model on my website: https://admixreality.com/ios26/ • If the login page appears, click “Check AR” and then “View in Your Space”. • On iOS 18 and earlier, sharing correctly sends the website URL. • On iOS 26, sharing sends the actual USDZ model file. This clearly demonstrates the regression and the security/IP issue.

Hi Apple Team and Community, We've encountered a sudden and widespread failure with the App Attest service starting today across multiple production apps and regions. The previously working implementation is now consistently returning the following error on iOS: The operation couldn’t be completed. (com.apple.devicecheck.error error 4.) (serverUnavailable) Despite the green status on Apple’s System Status page, this appears to be a backend issue—possibly infrastructure or DNS-related. Notably: The issue affects multiple apps. It is reproducible across different geographies. No code changes were made recently to the attestation logic. We previously reported a similar concern in this thread: App Attest Attestation Failing, but this new occurrence seems unrelated to any client-side cause. Update: An Apple engineer in this thread(https://developer.apple.com/forums/thread/782987) confirmed that the issue was due to a temporary DNS problem and has now been resolved. Can anyone else confirm seeing this today? Any insights from Apple would be appreciated to ensure continued stability. Thanks!

I have been able to save and remove ASPasskeyCredentialIdentities in the ASCredentialIdentityStore. But after saving a ASPasskeyCredentialIdentity, when I retrieve the current identities stored, it always returns an empty list. I check to make sure the store is enabled. I am using this method which is available starting with iOS 17.4: extension ASCredentialIdentityStore { public func credentialIdentities(forService serviceIdentifier: ASCredentialServiceIdentifier? = nil, credentialIdentityTypes: ASCredentialIdentityStore.IdentityTypes = []) async -> [any ASCredentialIdentity] } I have called it like this: store.credentialIdentities(forService: nil, credentialIdentityTypes: .passkey) And this: store.credentialIdentities() Has anyone got this to work?

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.

Summary I am investigating a change in macOS 26.1 (Tahoe) where plain (non-bundled) executables that request screen recording access no longer appear under: System Settings → Privacy & Security → Screen & System Audio Recording This behavior differs from macOS Sequoia, where these executables did appear in the list and could be managed through the UI. Tahoe still prompts for permission and still allows the executable to capture the screen once permission is granted, but the executable never shows up in the UI list. This breaks user expectations and removes UI-based permission management. To confirm the behavior, I created a small reproduction project with both: a plain executable, and an identical executable packaged inside an .app bundle. Only the bundled version appears in System Settings. Observed Behaviour 1. Plain Executable (from my reproduction project) When running a plain executable that captures the screen: macOS displays the normal screen-recording permission prompt. Before granting permission: screenshots show only the desktop background. After granting permission: screenshots capture the full display. The executable does not appear under “Screen & System Audio Recording”. Even when permission is granted manually (e.g., dragging the executable into the pane), the executable still does not appear, which prevents the user from modifying or revoking the permission through the UI. If the executable is launched from inside another app (e.g., VS Code, Terminal), the parent app appears in the list instead, not the executable itself. 2. Bundled App Version (from the reproduction project) I packaged the same code into a simple .app bundle (ScreenCaptureApp.app). When running the app: The same permission prompt appears. Pre-permission screenshots show the desktop background. Post-permission screenshots capture the full display. The app does appear under “Screen & System Audio Recording”. This bundle uses the same underlying executable — the only difference is packaging. Hypothesis macOS 26.1 (Tahoe) appears to require app bundles for an item to be shown in the Screen Recording privacy UI. Plain executables: still request and receive permission, still function correctly after permission is granted, but do not appear in the System Settings list. This may be an intentional change, undocumented behavior, or a regression. Reproduction Project The reproduction project includes: screen_capture.go A simple Go program that captures screenshots in a loop. screen_capture_executable Plain executable built from the Go source. ScreenCaptureApp.app/ App bundle containing the same executable. build.sh Builds both the plain executable and the app bundle. Permission reset and TCC testing scripts. The project demonstrates the behavior consistently. Steps to Reproduce Plain Executable Build: ./build.sh Reset screen capture permissions: sudo tccutil reset ScreenCapture Run: ./screen_capture_executable Before granting: screenshots show desktop only. Grant permission when prompted. After granting: full screenshots. Executable does not appear in “Screen & System Audio Recording”. Bundled App Build (if not already built): ./build.sh Reset permissions (optional): sudo tccutil reset ScreenCapture Run: open ScreenCaptureApp.app Before granting: screenshots show desktop. After granting: full screenshots. App bundle appears in the System Settings list. Additional Check I also tested launching the plain executable as a child process of another executable, similar to how some software architectures work. Result: Permission prompt appears Permission can be granted Executable still does not appear in the UI, even though TCC tracks it internally → consistent with the plain-executable behaviour. This reinforces that only app bundles are listed. Questions for Apple Is the removal of plain executables from “Screen & System Audio Recording” an intentional change in macOS Tahoe? If so, does Apple now require all screen-recording capable binaries to be packaged as .app bundles for the UI to display them? Is there a supported method for making a plain executable (launched by a parent process) appear in the list? If this is not intentional, what is the recommended path for reporting this as a regression? Files Unfortunately, I have discovered the zip file that contains my reproduction project can't be directly uploaded here. Here is a Google Drive link instead: https://drive.google.com/file/d/1sXsr3Q0g6_UzlOIL54P5wbS7yBkpMJ7A/view?usp=sharing Thank you for taking the time to review this. Any insight into whether this change is intentional or a regression would be very helpful.

Is there any particular reason why ASWebAuthenticationSession doesn't have support for async/await? (example below) do { let callbackURL = try await webAuthSession.start() } catch { // handle error } I'm curious if this style of integration doesn't exist for architectural reasons? Or is the legacy completion handler style preserved in order to prevent existing integrations from breaking?

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?

My app has been rejected by App Store review because the sign in with Apple functionality is not working properly. I'm able to reproduce the issue on my end but I don't understand why it's happening. I have two other apps that implement the same OAuth flow in an identical manner, and those apps have no issues signing in with Apple. I've copied my OAuth flow to a fresh project to see if that would make a difference, and it gives me the exact same error. In the simulator I get "invalid_request, invalid web redirect URL", and on-device the FaceID authentication fails with a very non-specific "Sign Up Not Completed" error. I'm completely out of ideas here, so any guidance would be appreciated. Thanks!

Hi! We are developing an authentication plugin for macOS that integrates with the system's authentication flow. The plugin is designed to prompt the user for approval via a push notification in our app before allowing access. The plugin is added as the first mechanism in the authenticate rule, followed by the default builtin:authenticate as a fallback. When the system requests authentication (e.g., during screen unlock), our plugin successfully displays the custom UI and sends a push notification to the user's device. However, I've encountered the following issue: If the user does not approve the push notification within ~30 seconds, the system resets the screen lock (expected behavior). If the user approves the push notification within approximately 30 seconds but doesn’t start entering their password before the timeout expires, the system still resets the screen lock before they can enter their password, effectively canceling the session. What I've Tried: Attempted to imitate mouse movement after the push button was clicked to keep the session active. Created a display sleep prevention assertion using IOKit to prevent the screen from turning off. Used the caffeinate command to keep the display and system awake. Tried setting the result as allow for the authorization request and passing an empty password to prevent the display from turning off. I also checked the system logs when this issue occurred and found the following messages: ___loginwindow: -[LWScreenLock (Private) askForPasswordSecAgent] | localUser = >timeout loginwindow: -[LWScreenLock handleUnlockResult:] _block_invoke | ERROR: Unexpected _lockRequestedBy of:7 sleeping screen loginwindow: SleepDisplay | enter powerd: Process (loginwindow) is requesting display idle___ These messages suggest that the loginwindow process encounters a timeout condition, followed by the display entering sleep mode. Despite my attempts to prevent this behavior, the screen lock still resets prematurely. Questions: Is there a documented (or undocumented) system timeout for the entire authentication flow during screen unlock that I cannot override? Are there any strategies for pausing or extending the authentication timeout to allow for complex authentication flows like push notifications? Any guidance or insights would be greatly appreciated. Thank you!

Hi all, I’m building a password manager app for iOS. The app implements an ASCredentialProviderExtension and has the entitlement com.apple.developer.authentication-services.autofill-credential-provider. From a UX perspective, I’d like to help users enable my app under: Settings → General → AutoFill & Passwords What I’ve observed: Calling UIApplication.openSettingsURLString only opens my app’s own Settings page, not the AutoFill list. Some apps (e.g. Google Authenticator) appear to redirect users directly into the AutoFill Passwords & Passkeys screen when you tap “Enable AutoFill.” 1Password goes even further: when you tap “Enable” in 1Password App, it shows a system pop-up, prompts for Face ID, and then enables 1Password as the AutoFill provider without the user ever leaving the app. Questions: Is there a public API or entitlement that allows apps to deep-link users directly to the AutoFill Passwords & Passkeys screen? Is there a supported API to programmatically request that my app be enabled as an AutoFill provider (similar to what 1Password seems to achieve)? If not, what is the recommended approach for guiding users through this flow? Thanks in advance!

Hi, This issue is happening during Passkey creation. We’ve observed that approximately 1% of our customer users encounter a persistent error during Passkey creation. For the vast majority, the process works as expected. We believe our apple-app-site-association file is correctly configured, served directly from the RP ID over HTTPS without redirects, and is up-to-date. This setup appears to work for most users, and it seems the Apple CDN cache reflects the latest version of the file. To help us diagnose and address the issue for the affected users, we would appreciate guidance on the following: What tools or steps does Apple recommend to identify the root cause of this issue? Are there any known recovery steps we can suggest to users to resolve this on affected devices? Is there a way to force a refresh of the on-device cache for the apple-app-site-association file? Thank you in advance for any input or guidance.

After registe Passkey with webauthn library, i create a passkeyRegistration with follow, let passkeyRegistration = ASPasskeyRegistrationCredential(relyingParty: serviceIdentifier, clientDataHash: clientDataHashSign, credentialID: credentialId, attestationObject: attestationObject) and then completeRegistrationRequest like that, extensionContext.completeRegistrationRequest(using: passkeyRegistration) But a bad outcome occurred from user agent. NotAllowedError:The request is not allowed by the user agent or the platform in the current context. And the return data rawID & credentialPublicKey is empty,

Hey there, I used our team's account to configure sign in with Apple, the mode is pop up, my clientId scope redirectUrl state are both correct. I got Failed to verify your identity. Try again., actually my account is valid because I can login to my mac and every apple website. I have tried many apple accounts and still got this error. That was so weird, I didn't find a solution online. Pls help me thanks.

Hey all, Question for the masses.... Does the Yubikey authentication have a OS dependency and it only works with a stable, public OS? Does Azure/Okta/Yubikey beta OS26? My CEO installed iPadOS 26 on his iPad and was not able to authenticate via Yubikey into our company environment. I ran the same scenario on my iPad using iPadOS 26 and I had the same results. Downgrading to iPAdOS doesn't pose these issues. I'm assuming something isn't fine-tuned yet?

I'm a bit confused about if using App Attest is possible in enterprise builds. It shows up under identifiers in the apple dev portal and I can add it to my provisioning file and entitlements file. But if I go to keys I cannot create a key for it. This page implies it can be used for enterprise builds: After distributing your app through TestFlight, the App Store, or the Apple Developer Enterprise Program, your app ignores the entitlement you set and uses the production environment.

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 &amp; 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.

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.

Binary code is associated with the NSUserTrackingUsageDescription deleted at present, but in the revised App privacy will contain NSUserTrackingUsageDescription, I feel very confused, don't know should shouldn't solve.
