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 grantin

Guideline 1.4.1 - Safety - Physical Harm
Hello everyone The application we developed is for pet medical care and is aimed at veterinarians The main function of the app is an AI conversation app, where the user talks to the AI. The AI answer content may involve disease diagnosis and treatment suggestions for pets. When we submitted it to the apple store for review, we received a 1.4.1 rejection notice (the app must clearly disclose data and methods to support accuracy claims related to health measurements) Our solutions Before entering the app, we have added a pop-up window (the pop-up window introduces that the output content of our app is generated by AI and cannot replace the malicious veterinary consultation and diagnosis. If you have health problems, please consult offline certified veterinarians and other content to ensure the safety of pets in a timely manner). Users must agree before proceeding to the next step of using the app. Our AI model has been registered with the algorithm (and we have also uploaded screenshots of the

Reply to Are read-only filesystems currently supported by FSKit?
Are read-only filesystems currently supported by FSKit? I think the tricky part here is what support here actually means. Let me start by what this actually does: pass the -r or -o rdonly options to the mount(8) command. Passing that to mount should mean that the VFS layer itself is prevented from writing to the device. In FSKit terms, that means FSBlockDeviceResource.writable should be false and that all write methods should fail. If either of those behave differently, then that's a HUGE bug that we'd need to fix ASAP. However, the confusing point here is that mounting a volume readonly doesn't necessarily define/change how the file system presents itself to the higher level system. That is, strictly speaking, nothing prevents a volume being mounted readonly... but that file system itself allowing itself to be fully modifiable. That might sound a bit strange, but as a concrete example, you could implement a resettable file system by using the on-disk file system as the starting structure, routing al

How to dynamically update an existing AVComposition when users add a new custom video clip?
I’m building a macOS video editor that uses AVComposition and AVVideoComposition. Initially, my renderer creates a composition with some default video/audio tracks: @Published var composition: AVComposition? @Published var videoComposition: AVVideoComposition? @Published var playerItem: AVPlayerItem? Then I call a buildComposition() function that inserts all the default video segments. Later in the editing workflow, the user may choose to add their own custom video clip. For this I have a function like: private func handlePickedVideo(_ url: URL) { guard url.startAccessingSecurityScopedResource() else { print(Failed to access security-scoped resource) return } let asset = AVURLAsset(url: url) let videoTracks = asset.tracks(withMediaType: .video) guard let firstVideoTrack = videoTracks.first else { print(No video track found) url.stopAccessingSecurityScopedResource() return } renderer.insertUserVideoTrack(from: asset, track: firstVideoTrack) url.stopAccessingSecurityScopedResource() } What I want to ac

General iOS/iPadOS 26 decoding bug: MP4 unexpectedly hangs, video image frozen, audio goes on
Playback of any kind of HD H.264 MP4 files (720p, 50fps) could randomly cause a stalled image. Playback does not stop in such a case. Image is frozen/stalled. Audio goes on. Timeline goes on. By tapping play/pause or scrubbing in the timeline, the playback recovers. It could also happen, if you are scrubbing in the timeline, especially to areas not loaded already (progressive MP4 download). Behaviour is always the same: image is stalled/frozen, audio goes on. To reproduce: use example project https://developer.apple.com/documentation/AVKit/playing-video-content-in-a-standard-user-interface Example file: https://www.keepinmind.info/test.mp4

Reply to [Core Bluetooth]The Application Playing a Notification Tone (AVAudioPlayer, System sounds) Should Automatically Route Audio to the Connected BLE accessory which uses HFP Profile
How do we programmatically ensure that these notification tones are automatically and reliably routed to the connected HFP headset Take a look at Routing audio to specific devices in multidevice sessions, which covers the direct issue of audio routing. __ Kevin Elliott DTS Engineer, CoreOS/Hardware

iOS BGProcessingTask + Background Upload Not Executing Reliably on TestFlight (Works in Debug)
iOS BGProcessingTask + Background Upload Not Executing Reliably on TestFlight (Works in Debug) Description: We are facing an issue with BGTaskScheduler and BGProcessingTask when trying to perform a background audio-upload flow on iOS. The behavior is inconsistent between Debug builds and TestFlight (Release) builds. Summary of the Problem Our application records long audio files (up to 1 hour) and triggers a background upload using: BGTaskScheduler BGProcessingTaskRequest Background URLSession (background with identifier) URLSession background upload task + AppDelegate.handleEventsForBackgroundURLSession In Debug mode (Xcode → Run on device), everything works as expected: BGProcessingTask executes handleEventsForBackgroundURLSession fires Background URLSession continues uploads reliably Long audio files successfully upload even when the app is in background or terminated However, in TestFlight / Release mode, the system does not reliably launch the BGProcessingTask or Background URL

Reply to AlarmKit play sound only once
Thank you for your post. When you do not provide your file to play, and you provide the default sound with sound: AlertConfiguration.AlertSound = .default, the sound will now be the default sound.he sound looping until you stop at what time? https://developer.apple.com/documentation/alarmkit/alarmmanager/alarmconfiguration/timer(duration:attributes:stopintent:secondaryintent:sound:) Do you have the time in a focused project with the sound file you are using to share it for people to give you ideas? If you're not familiar with preparing a test project, take a look at Creating a test project. Albert Pascual

Reply to iOS 26.1 PHPickerConfiguration.preselectedAssetIdentifiers doesn't select previous pictures in the PHPickerViewController
This sounds like a regression. Have you tried verifying if the identifiers are still valid when you try to use them again? You can do this by retrieving the assets using the identifier with the fetchAssets(withLocalIdentifiers:options:) method. See the article on Fetching Assets for more details. If the identifiers are valid and you’re still encountering the issue, please file a bug report. Include a minimal reproducible sample code and share the Feedback ID here so I can pass it on to the appropriate engineering team.
