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.

I am trying to communicate with the backend of my project. So I need to install the certificate into the simulator. I have the .pem file but when I drag-dropped it into the simulator, I got the error "Simulator device failed to complete the requested operation.". The simulator is an iPhone 16 Pro running iOS 18.5. Is there any way to install the cert to my simulator? PS: I can't use Apple Configurator or MDM because I am using the office's Mac. And I can't install anything there. So I can only do it manually.

Hi everyone 👋 I’m running into a persistent SSL issue on iOS where the app fails to establish a secure HTTPS connection to our backend APIs. The same endpoints work fine on Android and web, but on iOS the requests fail with: Error Domain=NSURLErrorDomain Code=-1200 "An SSL error has occurred and a secure connection to the server cannot be made." UserInfo={ NSLocalizedDescription = "An SSL error has occurred and a secure connection to the server cannot be made."; _kCFStreamErrorDomainKey = 3; _kCFStreamErrorCodeKey = -9802; } 🔍 What I’ve Checked: The servers use valid, trusted SSL certificates from a public CA TLS 1.2 and 1.3 are enabled The intermediate certificates appear correctly configured (verified using SSL Labs) The issue happens on our customer's end. (Got it via Sentry) Note: We recently removed NSAppTransportSecurity(NSAllowsArbitraryLoads) on our app, since all the endpoints use valid HTTPS certificates and standard configurations. ❓ Questions: Are there additional SSL validation checks performed by iOS when ATS is enabled? Has anyone seen similar behaviour, where valid certificate chains still trigger SSL errors? Any insights or debugging suggestions would be greatly appreciated 🙏

Hi, I’ve developed a custom Authorization Plugin and placed it under: /Library/Security/SecurityAgentPlugins/AuthPlugin.bundle I also updated the corresponding right in the authorization database (authorizationdb) to point to my plugin’s mechanism. However, when I invoke the right, my plugin does not get loaded. The system log shows the following errors: AuthorizationHostHelper: Init: unable to load bundle executable for plugin: AuthPlugin.bundle AuthorizationHostHelper: Processing request: Failed to create agent mechanism AuthPlugin:auth.startup.authenticate, failing authentication! Here’s what I’ve verified so far: The plugin bundle and its executable are signed and notarized successfully. The executable inside the bundle is universal (arm64 + x86_64). The bundle structure looks correct (Contents/Info.plist, Contents/MacOS/..., etc.). Despite that, the plugin fails to load at runtime. Could anyone provide advice on how to debug or trace why the SecurityAgent cannot load the bundle executable? Are there any entitlements, permissions, or SIP-related restrictions that might prevent custom authorization plugins from being loaded on modern macOS versions? Thanks in advance for any insights!

Hello, Thanks for the new video on Memory Integrity Enforcement! Is the presented app's sample code available (so that we can play with it and find & fix the bug on our own, using Soft Mode)? Thanks in advance!

I have an swift command line tool that changes proxy settings in system preferences via SystemConfiguration framework, does some stuff, and in the end reverts proxy settings back to original. Here is simplified code: var authorization: AuthorizationRef? let status = AuthorizationCreate(nil, nil, [], &authorization) let prefs = SCPreferencesCreateWithAuthorization(nil, "myapp" as CFString, nil, authorization) // change proxy setttings // do some stuff let prefs2 = SCPreferencesCreateWithAuthorization(nil, "myapp" as CFString, nil, authorization) // change proxy settings back to original When I try to change settings for the first time, the system dialog appears requesting permission to change network settings. If I try to change settings again within а short period of time, the dialog does not appear again. However, if it takes more than several minutes after first change, the dialog does appear again. Is there a way to create authorization, so that the dialog appears only once per app launch, no matter how much time passed since the first dialog?

I have an app (currently not released on App Store) which runs on both iOS and macOS. The app has widgets for both iOS and macOS which uses user preference (set in app) into account while showing data. Before upgrading to macOS 15 (until Sonoma) widgets were working fine and app was launching correctly, but after upgrading to macOS 15 Sequoia, every time I launch the app it give popup saying '“Kontest” would like to access data from other apps. Keeping app data separate makes it easier to manage your privacy and security.' and also widgets do not get user preferences and throw the same type of error on Console application when using logging. My App group for both iOS and macOS is 'group.com.xxxxxx.yyyyy'. I am calling it as 'UserDefaults(suiteName: Constants.userDefaultsGroupID)!.bool(forKey: "shouldFetchAllEventsFromCalendar")'. Can anyone tell, what am I doing wrong here?

Hi, I am just wondering if there is any option to protect my endpoints that will be used by Message Filtering Extension? According to the documentation our API has 2 endpoints: /.well-known/apple-app-site-association /[endpoint setup in the ILMessageFilterExtensionNetworkURL value of the Info.plist file] that the deferQueryRequestToNetwork will request on every message Since all requests to these 2 endpoints are made by iOS itself (deferQueryRequestToNetwork), I don't understand how I can protect these endpoints on my side, like API key, or maybe mTLS. The only way that I found is white list for Apple IP range. Is there other methods for it?

Hi, We are running into issues with iOS app prewarming, where the system launches our app before the user has entered their passcode. In our case, the app stores flags, counters, and session data in UserDefaults and the Keychain. During prewarm launches: UserDefaults only returns default values (nil, 0, false). We have no way of knowing whether this information is valid or just a placeholder caused by prewarming. Keychain items with kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly are inaccessible, which can lead to broken business logic (the app can assume no session exists). No special launch options or environment variables appear to be set. We can reproduce this 100% of the time by starting a Live Activity in the app before reboot. Here’s an example of the workaround we tried, following older recommendations: __attribute__((constructor)) static void ModuleInitializer(void) { char* isPrewarm = getenv("ActivePrewarm"); if (isPrewarm != NULL && isPrewarm[0] == '1') { exit(0); // prevent prewarm launch from proceeding } } On iOS 16+, the ActivePrewarm environment variable doesn’t seem to exist anymore (though older docs and SDKs such as Sentry reference it). We also tried listening for UIApplication.protectedDataDidBecomeAvailableNotification, but this is not specific to prewarming (it also fires when the device gets unlocked) and can cause watchdog termination if we delay work too long. Questions: Is there a supported way to opt out of app prewarming? What is the correct way to detect when an app is being prewarmed? Is the ActivePrewarm environment variable still supported in iOS 16+? Ideally, the UserDefaults API itself should indicate whether it is returning valid stored values or defaults due to the app being launched in a prewarm session. We understand opting out may impact performance, but data security and integrity are our priority. Any guidance would be greatly appreciated.

Summary CLLocationSourceInformation.isSimulatedBySoftware (iOS 15+) fails to detect location spoofing when using third-party tools like LocaChange, despite Apple's documentation stating it should detect simulated locations. Environment iOS 18.0 (tested and confirmed) Physical device with Developer Mode enabled Third-party location spoofing tools (e.g., LocaChange etc.) Expected Behavior According to Apple's documentation, isSimulatedBySoftware should return true when: "if the system generated the location using on-device software simulation. " Actual Behavior Tested on iOS 18.0: When using LocaChange sourceInformation.isSimulatedBySoftware returns false This occurs even though the location is clearly being simulated. Steps to Reproduce Enable Developer Mode on iOS 18 device Connect device to Mac via USB Use LocaChange to spoof location to a different city/country In your app, request location updates and check CLLocation.sourceInformation?.isSimulatedBySoftware Observe that it returns false or sourceInformation is nil Compare with direct Xcode location simulation (Debug → Simulate Location) which correctly returns true

Hi,is there an option to mark the file or folder or item stored in user defaults ... not to be backed up when doing unencrypted backup in iTunes?We are developing iOS app that contains sensitive data. But even if we enable Data Protection for the iOS app it can be backed up on mac unencrypted using iTunes. Is there a way to allow backing up content only if the backup is encrypted?

The header documentation for the (deprecated) LAContext.evaluatedPolicyDomainState property contains the following: @warning Please note that the value returned by this property can change exceptionally between major OS versions even if the state of biometry has not changed. I noticed that the documentation for the new LAContext.domainState property does not contain a similar warning. I also found this related thread from 2016/17. Is the domainState property not susceptible to changes between major OS versions? Or is this generally not an issue anymore?

Title's basically the whole question. I'm writing an SMS/Call Reporting extension (ILClassificationUIExtensionViewController). My goal is to keep everything on device and not use the built-in SMS/network reporting. To that end, I'm trying to write to a file in the App Group container from the classificationResponse handler. I'm getting Error 513: "You don’t have permission to save the file “classification_log.txt” in the [app group container folder]". I haven't been able to find much in the documentation on whether this behavior is enforced in classificationResponse handlers. Apple's barebones page on "SMS and Call Spam Reporting"[1] says "the system always deletes your extension’s container after your extension terminates," but that doesn't answer whether you can write to an App Group container. I haven't been able to find that answer elsewhere. ChatGPT and Gemini are both very sure it can be done. Any thoughts?

Hi guys, I need to configure a VPN to work only for specific apps. I already have a supervised iPhone, and I’ve successfully configured the VPN, but right now it applies to the whole phone. I need it to work just for some apps. I tried using both Apple Configurator and iMazing, but I can’t find this option there.

Macbook OS Version: macOS 14.7.3 (23H417) Mobile OS: iOS Mobile OS Version: iOS 18.6.2 Mobile Manufacturer: Apple Mobile Model: iPhone 12 Pro Max Page Type: vue vue Version: vue2 Packaging Method: Cloud Packaging Project Creation Method: HBuilderX Steps: The backend server is deployed on AWS in Japan with a Japanese IP. Packaging the APP in HBuilderX and publishing it to the Apple App Store were both successful. In a subsequent version, we planned to add a push notification feature and selected uniPush V2. Due to the separation of frontend and backend, the frontend APP implements functions such as registration, login, password change, page content display, and product lists through the server's RESTful APIs. Test colleagues reported that the APP could not load pages when used in Japan; however, it worked normally in China. In China: Pinging the server IP and domain from a MacBook was successful. Testing the API with Postman on a MacBook was successful. In Japan: Pinging the server IP and domain from a MacBook was successful. Testing the API with Postman on a MacBook failed with the error: HandshakeException: Connection terminated during handshake This appears to be an SSL communication failure. We tested the SSL certificate using www.ssllabs.com/ssltest and received an A+ rating. The certificate should not be an issue. we deselected uniPush V2, repackaged the APP, and uploaded it to TestFlight. The result remained the same: the APP content failed to load in Japan, while it worked normally in China. Expected Result: Access to the Japanese server APIs should work normally both in China and Japan. Actual Result: The APP content fails to load when used in Japan, but works normally in China.

Our app server is having some TLS related issue with the new iOS 26 (It works with iOS 18 and below). When opening the domain url in iPhone Safari browser with iOS 26, it showing the error as below: We followed the instructions from this link (https://support.apple.com/en-sg/122756), to run the following command: nscurl --tls-diagnostics https://test.example in Terminal app. It shows TLS failed with error: -9808 Could anyone please help explain what exactly the issue is with our server certificate, and how we should fix it? Thanks so much!

With Let's Encrypt having completely dropped support for OCSP recently [1], I wanted to ask if macOS has a means of keeping up to date with their CRLs and if so, roughly how often this occurs? I first observed an issue where a revoked-certificate test site, "revoked.badssl.com" (cert signed by Let's Encrypt), was not getting blocked on any browser, when a revocation policy was set up using the SecPolicyCreateRevocation API, in tandem with the kSecRevocationUseAnyAvailableMethod and kSecRevocationPreferCRL flags. After further investigation, I noticed that even on a fresh install of macOS, Safari does not block this test website, while Chrome and Firefox (usually) do, due to its revoked certificate. Chrome and Firefox both have their own means of dealing with CRLs, while I assume Safari uses the system Keychain and APIs. I checked cert info for the site here [2]. It was issued on 2025-07-01 20:00 and revoked an hour later. [1] https://letsencrypt.org/2024/12/05/ending-ocsp/ [2] https://www.ssllabs.com/ssltest/analyze.html?d=revoked.badssl.com

Hi! I'm trying to prototype a macOS app related to wifi features. The main hiccup I've encountered is "Connect to a saved network without re-entering the network password". So far I've been unsuccessful in this without entering the password manually each time asking the user for authentication to access the saved network in keychain I read somewhere on the internet that CWInterface.associate would use saved credentials automatically if you gave a nil password, but my attempts have proven that to be false. Is this not currently available because it raises security concerns, or it just hasn't been considered? Or am I missing a way to do this? I don't need access to the credentials, just for the system to connect for me.
