Hello, I have a customer who keeps getting an "app is damaged" error for a freshly downloaded app from the Mac App Store. The logs show the following lines: standard 12:58:40.390872+0200 storeuid Receipt Validation (at.EternalStorms.Yoink) Signature Check: PASS Bundle ID Check: PASS Bundle Version Check: PASS GUID Check: PASS Expiration Check: PASS standard 12:58:40.391649+0200 storelegacy StoreLegacy: Failed to perform in-line receipt renewal for application at path /Applications/Yoink.app : '(null)' The Mac in question is running macOS 12 Monterey - curiously, the customer has another Mac with that same system version and there it works just fine. What can be done to make this work again? Thank you, – Matthias

Hello, with macOS Sequoia I've observed a sudden, substantial surge in reports about the Mac App Store version of my app Yoink no longer accepting files dropped to it, with the following message being logged in Console.app: 08:16:05.516307+0200 Yoink ---Yoink Error--- Could not create NSURL bookmark for /Users/<redacted>/Downloads/<redacted>/<redacted>.txt err: Error Domain=NSCocoaErrorDomain Code=256 "Failed to retrieve app-scope key" UserInfo={NSDebugDescription=Failed to retrieve app-scope key} The code line that causes this is the following: NSData *bmData = [fileURL bookmarkDataWithOptions:NSURLBookmarkCreationWithSecurityScope includingResourceValuesForKeys:nil relativeToURL:nil error:&err]; Sometimes a relaunch of Yoink, or a restart of the Mac resolves the issue, but only temporarily. Other times, even a restart doesn't work, but running tccutil reset All at.EternalStorms.Yoink in Terminal and then restarting the Mac works (again, temporarily). The trial version and Setapp versions of my app both work as expected, however. I myself cannot reproduce this issue, so any pointers would be greatly appreciated. (This might be considered a follow up to https://developer.apple.com/forums/thread/46583 , years back) Thanks a ton, – Matthias

Hi all, with my app ScreenFloat, you can record your screen, along with system- and microphone audio. Those two audio feeds are recorded into separate audio tracks in order to individually remove or edit them later on. Now, these recordings you create with ScreenFloat can be drag-and-dropped to other apps instantly. So far, so good, but some apps, like Slack, or VLC, or even websites like YouTube, do not play back multiple audio tracks, just one. So what I'm trying to do is, on dragging the video recording file out of ScreenFloat, instantly baking together the two individual audio tracks into one, and offering that new file as the drag and drop file, so that all audio is played in the target app. But it's slow. I mean, it's actually quite fast, but for drag and drop, it's slow. My approach is this: "Bake together" the two audio tracks into a one-track m4a audio file using AVMutableAudioMix and AVAssetExportSession Take the video track, add the new audio file as an audio track to it, and render that out using AVAssetExportSession For a quick benchmark, a 3'40'' movie, step 1 takes ~1.7 seconds, and step two adds another ~1.5 seconds, so we're at ~3.2 seconds. That's an eternity for a drag and drop, where the user might cancel if there's no immediate feedback. I could also do it in one step, but then I couldn't use the AV*Passthrough preset, and that makes it take around 32 seconds then, because I assume it touches the video data (which is unnecessary in this case, so I think the two-step approach here is the fastest). So, my question is, is there a faster way? The best idea I can come up with right now is, when initially recording the screen with system- and microphone audio as separate tracks, to also record both of them into a third, muted, "hidden" track I could use later on, basically eliminating the need for step one and just ripping the two single audio tracks out of the movie and only have the video and the "hidden" track (then unmuted), but I'd still have a ~1.5 second delay there. Also, there's the processing and data overhead (basically doubling the movie's audio data). All this would be great for an export operation (where one expects it to take a little time), but for a drag-and-drop operation, it's not ideal. I've discarded the idea of doing a promise file drag, because many apps do not accept those, and I want to keep wide compatibility with all sorts of apps. I'd appreciate any ideas or pointers. Thank you kindly, Matthias

Hello, is there a way to implement Continuity Markup in our own apps? (This is what I'm talking about: https://support.apple.com/en-us/102269 , scroll down to "Use Continuity Markup"). Also, why does a QuickLook panel (QLPreviewPanel.shared()) not display the markup options when triggered from my app for png image files in my app's Group Container? Do I need to implement certain NSServicesMenuRequestor methods for that? Sadly, I could not find any docs on that. Thank you, – Matthias

Hi 🙋 Has anybody gotten subtitles in macOS Tahoe Control Widgets to show up in their custom control widgets? Seems macOS is able to do it (see attached screenshot of the Bluetooth control widget), but my widget, which shows a title and subtitle on iOS, will only show the title on macOS. I tried all the different ControlWidgetButton init methods to no avail. I tried a VStack for my title and subtitle Texts, I tried just two Texts without a VStack, I tried the controlWidgetStatus and controlWidgetActionHint modifiers out of desperation... nothing worked. Any pointers much appreciated! Thank you, – Matthias
