Hi, A certificate imported on macOS 15 using the security command with the "non-exportable" option was imported in an exportable state. I would like to know how to change this certificate to be non-exportable. Regards, CTJ

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!

When we enable 3rd party authentication plugin using SFAuthorization window, then when user performs Lock Screen and then unlock the MAC. Now after unlock, if user tries to open Keychain Access, it is not getting opened. When trying to open Keychain Access, we are prompted for credentials but after providing the credentials Keychians are not getting opened. This is working on Sonoma 14.6.1 , but seeing this issue from macOS Sequoia onwards. Are there any suggested settings/actions to resolve this issue?

Hello, I have a fully functional webauthn relying party that uses passkeys and I am trying to implement an iOS sdk for it. On the server, the AASA file is valid and well served at /.well-known/assetlinks.json. I verified its validity with branch.io and that it is indeed cached by Apple's CDN (https://app-site-association.cdn-apple.com/a/v1/service.domain.com), but even will all these I still get the following error when installing the app on a device and starting the passkey ceremony: Passkey authorization failed. Error: The operation couldn’t be completed. Application with identifier TEAM.com.APP is not associated with domain service.domain.com So I then checked the system log when installing the app on my iPhone, and under the swcd process (which is apparently responsible of fetching the AASA file) I found the following error: swcd: Domain is invalid. Will not attempt a download. The issue that I have is that my domain is actually an IDN, it has a special character in it. But everywhere I have used it, I converted it to ASCII (punycode). With this conversion, Apple's CDN is able to fetch the AASA file, and the passkey ceremony works fine on a browser. So I don't understand how the device (both iPhone or Mac) finds this domain to be invalid? In the app's entitlements, I added the capability for an associated domain, with webcredentials:service.domain.com with the domain name converted to ASCII (punycode) and developer mode doesn't address this issue as it appears when the app is installed (and is not related to Apple's CDN). The last thing I tried was to add the domain with special characters in the app's entitlements (for webcredentials:) but then Xcode was unable to install the app on the device, and gave the following error: Failed to verify code signature (A valid provisioning profile for this executable was not found.) which happened only with a special character in the domain in the app's entitlements. All this leaves me kind of in a dead end, I understand Xcode or iOS/macOS has a hard time with IDNs and special characters (so do I), but I have no idea on how to solve this (without changing the domain name), so I would really appreciate any help. Thanks in advance. PS: I tested all this previously with another domain without special characters and it was working. It also had dashes ('-') in it and the new domain converted to ASCII is basically a regular domain with '-' in it so I suppose there is some kind of conversion made from ASCII back to special characters and that then, the domain is considered as invalid, but this doesn't really help me a lot... PS2: My devices are running on iOS 17.4.1 and macOS 14.4.1 with Xcode 15.2

I'm developing an iOS app that utilizes Universal Links and ASWebAuthenticationSession to deep-link from a website to the app itself. This implementation adheres to the recommendations outlined in RFC 8252, ensuring that the app opening the ASWebAuthenticationSession is the same app that is launched via the Universal Link. Problem: 　While most users can successfully launch the app via Universal Links,a few percent of users experience instances where the app fails to launch, and the user is redirected to the browser. What I've Tried: 　ASWebAuthenticationSession Configuration: I've double-checked the configuration of callbackURLScheme and presentationContextProvider. 　Universal Links: Verified the apple-app-site-association file and associated domains entitlement. 　Network Conditions: Tested on various network environments (Wi-Fi, cellular) and devices. Questions: 　What are the potential causes for this behavior? 　Has anyone else encountered a similar issue and found a solution? 　Are there any debugging techniques or ways to generate more detailed logs? I haven't been able to determine which device or OS version is causing this problem. 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?

FB18383742 Setup 🛠️ Xcode 16.4 (16F6) 📱 iPhone 13 mini (iOS 18.0.1) ⌚️ Apple Watch Series 10 (watchOS 11.3.1) Observations As AccessorySetupKit does not request "Core Bluetooth permissions", when a watchOS companion app is installed after having installed the iOS app, the toggle in the watch settings for Privacy & Security > Bluetooth is turned off and disabled After removing the iPhone associated with the Apple Watch, Bluetooth works as expected in the watchOS app Upon reinstalling the iOS app, there's a toggle for Bluetooth in the iOS ASK app's settings and the ASK picker cannot be presented 🤨 From ASK Documentation: AccessorySetupKit is available for iOS and iPadOS. The accessory’s Bluetooth permission doesn’t sync to a companion watchOS app. But this doesn't address not being able to use Core Bluetooth in a watch companion app at all 🥲 Reproducing the bug Install the iOS + watchOS apps Launch iOS app, tap "start scan", observe devices can be discovered (project is set up to find heart rate monitors) Launch watchOS, tap allow on Bluetooth permission pop-up watchOS app crashes 💥 Meanwhile, in the iOS app, there should be a log entry for 💗 CBCentralManager state: poweredOff and the ASK picker is no longer able to discover any devices The state of the device permissions: iOS app has no paired accessories or Bluetooth permission watchOS app's Bluetooth permission shown as turned off & disabled Remove the iOS app Relaunch the watchOS app Notice the CBCentralManager state is unauthorized Remove and reinstall the watchOS app Tap allow on Bluetooth permission pop-up watchOS app does not crash and CBCentralManager state is poweredOn The state of the watch permissions: Bluetooth is turned on & the toggle is not disabled Note that at this time the iOS app is not installed, there is no way to remove Bluetooth permission for the watch app. Reinstall + launch the iOS app Notice a warning in the log: [##### WARNING #####] App has companion watch app that maybe affected if using CoreBluetooth framework.

Is this the expected error? 🤔 The state of the iOS permissions: The app's settings show a Bluetooth toggle normally associated with Core Bluetooth, but the app never showed a Core Bluetooth pop-up The iOS ASK app now has Core Bluetooth permission 😵‍💫 Following up with Apple This is a known bug that should be fixed in watchOS 26 when Bluetooth permissions for watch apps can be set independently of the iOS app. I've yet to test it with watchOS 26. See repo for the same post with screenshots of the settings and demo code reproducing the bug: https://github.com/superturboryan/AccessorySetupKit-CoreBluetooth-watchOS-Demo

(Xcode 26.2, iPhone 17 Pro) I can't seem to get hardware tag checks to work in an app launched without the special "Hardware Memory Tagging" diagnostics. In other words, I have been unable to reproduce the crash example at 6:40 in Apple's video "Secure your app with Memory Integrity Enforcement". When I write a heap overflow or a UAF, it is picked up perfectly provided I enable the "Hardware Memory Tagging" feature under Scheme Diagnostics. If I instead add the Enhanced Security capability with the memory-tagging related entitlements: I'm seeing distinct memory tags being assigned in pointers returned by malloc (without the capability, this is not the case) Tag mismatches are not being caught or enforced, regardless of soft mode The behaviour is the same whether I launch from Xcode without "Hardware Memory Tagging", or if I launch the app by tapping it on launchpad. In case it was related to debug builds, I also tried creating an ad hoc IPA and it didn't make any difference. I realise there's a wrinkle here that the debugger sets MallocTagAll=1, so possibly it will pick up a wider range of issues. However I would have expected that a straight UAF would be caught. For example, this test code demonstrates that tagging is active but it doesn't crash: #define PTR_TAG(p) ((unsigned)(((uintptr_t)(p) >> 56) & 0xF)) void *p1 = malloc(32); void *p2 = malloc(32); void *p3 = malloc(32); os_log(OS_LOG_DEFAULT, "p1 = %p (tag: %u)\n", p1, PTR_TAG(p1)); os_log(OS_LOG_DEFAULT, "p2 = %p (tag: %u)\n", p2, PTR_TAG(p2)); os_log(OS_LOG_DEFAULT, "p3 = %p (tag: %u)\n", p3, PTR_TAG(p3)); free(p2); void *p2_realloc = malloc(32); os_log(OS_LOG_DEFAULT, "p2 after free+malloc = %p (tag: %u)\n", p2_realloc, PTR_TAG(p2_realloc)); // Is p2_realloc the same address as p2 but different tag? os_log(OS_LOG_DEFAULT, "Same address? %s\n", ((uintptr_t)p2 & 0x00FFFFFFFFFFFFFF) == ((uintptr_t)p2_realloc & 0x00FFFFFFFFFFFFFF) ? "YES" : "NO"); // Now try to use the OLD pointer p2 os_log(OS_LOG_DEFAULT, "Attempting use-after-free via old pointer p2...\n"); volatile char c = *(volatile char *)p2; // Should this crash? os_log(OS_LOG_DEFAULT, "Read succeeded! Value: %d\n", c); Example output: p1 = 0xf00000b71019660 (tag: 15) p2 = 0x200000b711958c0 (tag: 2) p3 = 0x300000b711958e0 (tag: 3) p2 after free+malloc = 0x700000b71019680 (tag: 7) Same address? NO Attempting use-after-free via old pointer p2... Read succeeded! Value: -55 For reference, these are my entitlements.

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.

I’m using a custom Installer plug-in (InstallerPane) to collect sensitive user input (username/password) during install. After the payload is laid down, I need to send those values to a newly installed agent (LaunchAgent) to persist them. What I tried I expose an XPC Mach service from the agent and have the plug-in call it. On the agent side I validate the XPC client using the audit token → SecCodeCopyGuestWithAttributes → SecCodeCheckValidity. However, the client process is InstallerRemotePluginService-* (Apple’s view service that hosts all plug-ins), so the signature I see is Apple’s, not mine. I can’t distinguish which plug-in made the call. Any suggestion on better approach ?

Hi, I have a set of plugins which are registered for login. One of them is a custom ui view for the login screen. The scenario: 1.DisableFDEAutoLogin is false. 2.The User logs in to the file vault login screen. 3.The security plugins are activated, and working. 4.We get any kind of an error from the plugins, and therefore the login fails. 5.We get a native login screen, after the denial of authorization. 6.In case that DisableFDEAutoLogin is true, I do get the custom login screen, after the file vault login. My question: Why dont I see the custom login screen, after the auto login fails? Cheers Sivan

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

I am new to swift development, and it's possible that I'm missing something fundamental/obvious. If so, I apologize in advance. My team is developing an application for iPadOS using SwiftUI, and I'm trying to accomplish something similar to what the original inquirer is asking for in this thread: https://developer.apple.com/forums/thread/725152. The only difference is that I'm trying to use a PIV smart card to achieve authentication to a server rather than digitally sign a document. Unfortunately, I'm getting stuck when attempting to run the list() function provided in the accepted answer to the post mentioned above. When attempting to call SecItemCopyMatching(), I'm getting a -34018 missing entitlement error. I've attempted to add the com.apple.token to my app's keychain-access-groups entitlements, but this does not resolve the issue. I have checked the entitlements in my built app, per the recommendation in the troubleshooting guide here: https://developer.apple.com/forums/thread/114456. The entitlement for com.apple.token is indeed present in the plist. Based on other documentation I've read, however, it seems that the explicit declaration of com.apple.token should not even be required in the entitlements. Is there something obvious that I'm missing here that would prevent my app from accessing the token access group?

I am trying to setup remote Java debugging between two machines running macOS (15.6 and 26). I am able to get the Java program to listen on a socket. However, I can connect to that socket only from the same machine, not from another machine on my local network. I use nc to test the connection. It reports Connection refused when trying to connect from the other machine. This issue sounds like it could be caused by the Java program lacking Local Network system permission. I am familiar with that issue arising when a program attempts to connect to a port on the local network. In that case, a dialog is displayed and System Settings can be used to grant Local Network permission to the client program. I don't know whether the same permission is required on the program that is receiving client requests. If it is, then I don't know how to grant that permission. There is no dialog, and System Settings does not provide any obvious way to grant permission to a program that I specify. Note that a Java application is a program run by the java command, not a bundled application. The java command contains a hard-wired Info.plist which, annoyingly, requests permission to use the microphone, but not Local Network access.

I work for Brave, a browser with ~80M users. We want to introduce a new system for automatic updates called Omaha 4 (O4). It's the same system that powers automatic updates in Chrome. O4 runs as a separate application on users' systems. For Chrome, this works as follows: An app called GoogleUpdater.app regularly checks for updates in the background. When a new version is found, then GoogleUpdater.app installs it into Chrome's installation directory /Applications/Google Chrome.app. But consider what this means: A separate application, GoogleUpdater.app, is able to modify Google Chrome.app. This is especially surprising because, for example, the built-in Terminal.app is not able to modify Google Chrome.app. Here's how you can check this for yourself: (Re-)install Chrome with its DMG installer. Run the following command in Terminal: mkdir /Applications/Google\ Chrome.app/test. This works. Undo the command: rm -rf /Applications/Google\ Chrome.app/test Start Chrome and close it again. mkdir /Applications/Google\ Chrome.app/test now fails with "Operation not permitted". (These steps assume that Terminal does not have Full Disk Access and System Integrity Protection is enabled.) In other words, once Chrome was started at least once, another application (Terminal in this case) is no longer allowed to modify it. But at the same time, GoogleUpdater.app is able to modify Chrome. It regularly applies updates to the browser. For each update, this process begins with an mkdir call similarly to the one shown above. How is this possible? What is it in macOS that lets GoogleUpdater.app modify Chrome, but not another app such as Terminal? Note that Terminal is not sandboxed. I've checked that it's not related to codesigning or notarization issues. In our case, the main application (Brave) and the updater (BraveUpdater) are signed and notarized with the same certificate and have equivalent requirements, entitlements and provisioning profiles as Chrome and GoogleUpdater. The error that shows up in the Console for the disallowed mkdir call is: kernel (Sandbox) System Policy: mkdir(8917) deny(1) file-write-create /Applications/Google Chrome.app/foo (It's a similar error when BraveUpdater tries to install a new version into /Applications/Brave Browser.app.) The error goes away when I disable System Integrity Protection. But of course, we cannot ask users to do that. Any help would be greatly appreciated.

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?

Hi, my app is receiving all keyboard events through Input Monitoring preference. It completely stopped to work on macOS 15 Sequoia and I have no idea why. Where can I read what has been changed in Input Monitoring? Thanks!

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. From: https://blog.greenrobot.com/2025/11/10/i-have-a-decision-to-make/ Related post: https://developer.apple.com/forums/thread/806187 I submitted a code level tech support question for this. They directed me here.

Our app uses Face ID to optionally secure access to the app for device owner. This not the new 'Require Face ID' feature of iOS 18 - this is our own custom implementation that has some other related logic for authentication handling. Starting in iOS 18.3.1, starting the app results in multiple Face Id checks being fired - sometimes just a couple but sometimes many more. Curiously, this is happening even when I completely disable any code we have that prompts for Face ID. It appears to come from nowhere. This does not happen on prior iOS 18 releases so, while I might be doing something improper in the code, something specific has changed in iOS 18.3.1 to cause this issue to manifest. I'm looking for advice as to what could be occurring here, how to debug a Face Id check that appears to come from nowhere, and what, if any, workarounds exist.

Hi, When calling generateAssertion on DCAppAttestService.shared, it gives invalidKey error when there was an update for an offloaded app. The offloading and reinstall always works fine if it is the same version on app store that was offloaded from device, but if there is an update and the app tries to reuse the keyID from previous installation for generateAssertion, attestation service rejects the key with error code 3 (invalid key) for a significant portion of our user. In our internal testing it failed for more than a third of the update attempts. STEPS TO REPRODUCE: install v1 from app store generate key using DCAppAttestService.shared.generateKey Attest this key using DCAppAttestService.shared.attestKey Send the attestation objection to our server and verify with apple servers Generate assertions for network calls to backend using DCAppAttestService.shared.generateAssertion with keyID from step 2 Device offloads the app (manually triggered by user, or automatically by iOS) A new version v2 is published to App Store Use tries to open the app Latest version is download from the App Store App tries to use the keyID from step 2 to generate assertions DCAppAttestService throws invalidKey error (Error Domain=com.apple.devicecheck.error Code=3) Step 7 is critical here, if there is no new version of the app, the reinstalled v1 can reuse the key from step 2 without any issues Is this behaviour expected? Is there any way we can make sure the key is preserved between offloaded app updates? Thanks
