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 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.
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.
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.

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 everyone,
I’m encountering an unexpected Keychain behavior in a production environment and would like to confirm whether this is expected or if I’m missing something.
In my app, I store a deviceId in the Keychain based on the classic KeychainItemWrapper implementation. I extended it by explicitly setting:
kSecAttrAccessible = kSecAttrAccessibleAfterFirstUnlock
My understanding is that kSecAttrAccessibleAfterFirstUnlock should allow Keychain access while the app is running in the background, as long as the device has been unlocked at least once after reboot.
However, after the app went live, I observed that when the app performs background execution (e.g., triggered by background tasks / silent push), Keychain read attempts intermittently fail with:
errSecInteractionNotAllowed (-25308)
This seems inconsistent with the documented behavior of kSecAttrAccessibleAfterFirstUnlock.
Additional context:
The issue never occurs in foreground.
The issue does not appear on development devices.
User devices are not freshly rebooted when this happens.
The Keychain item is created successfully; only background reads fail.
Setting the accessibility to kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly produces the same result.
Questions:
Under what circumstances can kSecAttrAccessibleAfterFirstUnlock still cause a -25308 error?
Is there any known restriction when accessing Keychain while the app is running in background execution contexts?
Could certain system states (Low Power Mode, Background App Refresh conditions, device lock state, etc.) cause Keychain reads to be blocked unexpectedly?
Any insights or similar experiences would be greatly appreciated. Thank you!
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.

I have a binary executable which needs to be given Accessibility Permissions so it can inject keypresses and mouse moves. This was always possible up to macOS 15 - when the first keypress arrived the Accessibility Permissions window would open and allow me to add the executable. However this no longer works in macOS 26: the window still opens, I navigate to the executable file and select it but it doesn't appear in the list. No error message appears.
I'm guessing that this may be due to some tightening of security in Tahoe but I need to figure out what to change with my executable to allow it to work.
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?

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 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.
Issue: Plain Executables Do Not Appear Under “Screen & System Audio Recording” on macOS 26.1 (Tahoe)
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?

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.
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.

I'm told the two apps are two views of the same data, so I guess some filter must be being applied?

Our background monitoring application uses a Unix executable that requests Screen Recording permission via CGRequestScreenCaptureAccess(). This worked correctly in macOS Tahoe 26.0.1, but broke in 26.1.
Issue:
After calling CGRequestScreenCaptureAccess() in macOS Tahoe 26.1:
System dialog appears and opens System Settings
Our executable does NOT appear in the Screen Recording list
Manually adding via "+" button grants permission internally, but the executable still doesn't show in the UI
Users cannot verify or revoke permissions
Background:
Unix executable runs as a background process (not from Terminal)
Uses Accessibility APIs to retrieve window titles
Same issue occurs with Full Disk Access permissions
Environment:
macOS Tahoe 26.1 (worked in 26.0.1)
Background process (not launched from Terminal)
Questions:
Is this a bug or intentional design change in 26.1?
What's the recommended approach for background executables to properly register with TCC?
Are there specific requirements (Info.plist, etc.) needed?
This significantly impacts user experience as they cannot manage permissions through the UI.
Any guidance would be greatly appreciated. Thank you
Why can’t sandboxed mac app store apps have full disk access available in the system settings for full disk access?
I discovered mac app store apps in release mode cannot access the ai auggie command line program and other command line programs like opengrep on your system. Debug builds fine.
I came up with a workaround: Since I have an ssh client built in for connecting to remote servers, why not connect to ssh on the same local machine… Ask the user for their username and password in a popup.
To do this, you have to enable remote login on your mac in system settings -> sharing.
In addition you must grant full disk access to cli ssh in system settings: add /usr/libexec/sshd-keygen-wrapper
It all works, but I don’t see the cli program in mac settings. To remove the cli program you must run a command line program to remove all full disk access support from all apps. No way to just undo ssh.
So my question is, even though I got CodeFrog all working for a mac app store release, should I not do it because it’s insecure or too complicated with the system settings? Should I instead sell the app off the store like Panic Nova?
Need some advice. I have not implemented in app purchases yet. Should I just have a reality check and sell the app off the store, or try for app store approval?
Bummer…
Maybe I’m ahead of my time, but perhaps Apple could review the source code for apps requesting full disk access and make sure there’s nothing fraudulent in them. Then, developer tools app store apps could be in the store with the user’s assurance that nothing is happening behind the scenes that is scary.

I submitted a code level tech support question for this. They directed me here.
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 cannot find any reference to this within the Apple developer documents (or certainly searching for multiple possible keywords yields no results).
The only reference I can find is to documents written in support of its announcement in 2002: https://developer.apple.com/news/?id=huqjyh7k.
Is there any further documentation on implementing or has the capability been deprecated?
