I have the following code running on macOS and iOS: CKQuerySubscription *zsub = [[CKQuerySubscription alloc] initWithRecordType:ESS_CLOUDCONTROLLER_RECORDTYPE_PUSHNOTE predicate:[NSPredicate predicateWithFormat:@"TRUEPREDICATE"] subscriptionID:@"pushZSub" options:CKQuerySubscriptionOptionsFiresOnRecordUpdate|CKQuerySubscriptionOptionsFiresOnRecordCreation|CKQuerySubscriptionOptionsFiresOnRecordDeletion]; zsub.zoneID = zid; CKNotificationInfo *inf = [[CKNotificationInfo alloc] init]; inf.shouldSendContentAvailable = YES; inf.desiredKeys = @[ESS_PN_RECORDFIELD_KEY_OVERALLDATE]; zsub.notificationInfo = inf; CKModifySubscriptionsOperation *msop = [[CKModifySubscriptionsOperation alloc] initWithSubscriptionsToSave:@[zsub] subscriptionIDsToDelete:nil]; msop.qualityOfService = NSQualityOfServiceUserInitiated; msop.modifySubscriptionsCompletionBlock = ^(NSArray<CKSubscription *> * _Nullable savedSubscriptions, NSArray<CKSubscriptionID> * _Nullable deletedSubscriptionIDs, NSError * _Nullable operationError) { dispatch_async(dispatch_get_main_queue(), ^{ if (savedSubscriptions.count == 1) { //works also when already created. compH(YES, nil); } else { compH(NO, nil); } }); }; [self.database addOperation:msop]; (code synopsis: after i create a custom zone (not shown in code), I add a ckquerysubscription to it for a specific record type, configured as a silent notification) When I change the according record in my Mac app, I get an immediate silent push on iOS. On macOS, however, after I change the record in my iOS app, I don't get one. Sometimes, one silent push makes it through every now and then a minute+ late or so, and after that, it's going missing again. What's the deal? Everything's set up correctly (com.apple.developer.aps-environment is set, container-identifiers are the same, icloud services are the same, ubiquity-kvstore-identifier are the same). I obviously register for remote notifications in both apps. I see all the records and subscriptions and zones in both the Mac and iOS app. I tried setting alertBody to an empty string, or soundName to an empty string, or both to an empty string: no difference I tried having different subscriptions for my Mac and iOS app, since they use different bundle ids, but that was merged into one subscription server-side, so I'm thinking that's not it I tried making it not-silent by setting contentAvailable to NO and adding a full alertBody, title and subtitle. Again, worked on iOS, not on macOS. This has been going on since macOS 14 Sonoma (when I first got reports of this. Now running on macOS 26.3). Before Sonoma, it worked just fine. Now I thought perhaps it's because I had a subscription on the default zone, and not a custom one, so I tried subscribing to changes on a record in a custom zone (see code above), but that did not change anything either. It's all working fine, only the push notifications are not making it through to the Mac app. If I sudo killall apsd (kill the push service daemon), the last push notification suddenly miraculously makes it through, by the way. At this point, I'm out of ideas and would very much appreciate pointers as to how to debug this. Polling every 30 seconds for changes is so 1990s. Speaking of which, this is a rather long-time-running app (started in 2011). Could my CloudKit database be “too old” or “corrupted” or whatever? Thank you kindly, – Matthias

Hello. In my app, I use RegisterEventHotkey to implement global keyboard shortcuts to trigger actions. Up until macOS Sequoia, I was able to use a keyboard shortcut with option and shift as the modifiers, like option shift 2 (⌥ ⇧ 2). Now, on macOS Sequoia, using RegisterEventHotkey to register a hotkey with those exact modifiers (option and shift), regardless of the key, fails with the error -9868 (eventInternalErr). Is this a documented and wanted change, or is this a bug? Other modifier keys (just command, command option, command shift, command control, control shift, etc), all work. Any insight into this would be appreciated. (Feedback filed: FB15163561) 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

Hello, I hope to find out more about how AppTransaction works on macOS, specifically about its internet connection requirements: if I use this to validate that the app is a legit purchase from the Mac App Store, I would not want it to have an always-on requirement just to validate. Does AppTransaction require the user to always be online for AppTransaction.shared ? When an app is downloaded from the Mac App Store, is the data needed for AppTransaction automatically embedded during that download, or is that data downloaded upon first launch of the app, therefore requiring an internet connection at launch time? Once the data/receipt has been downloaded by AppTransaction, is it cached until the app's next update, or is it cleared at some time during the version's life and needs to be re-downloaded, therefore requiring an internet connection at launch? Where is that receipt/data stored? Also, if you don't mind me sneaking in this non-related but sort of related question, in terms of receipt validation: Does macOS Sequoia's MAC address rotation feature affect receipt validation in any way when using IOKit? 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 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, 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, I've recently observed a sudden increase in support requests for one of my apps on the Mac App Store, reporting the error " is damaged and can't be opened. Please re-download it from the Mac App Store", all on different systems: macOS 12, macOS 13, and macOS 15 Sequoia. Re-downloading does not resolve the issue most of the time. One user reported that being connected to the internet resolved it - perhaps this is an OCSP issue again? I myself cannot reproduce this issue. Has there been a change in code-signing recently? Have some certificates changed? Anything else I should be aware of? What is the best course of action to have users take who experience this, when re-downloading the app from the Mac App Store does not work? Thank you, – Matthias

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, I'd like to find out if macOS Sequoia's MAC Address randomization affects the data (specifically, MAC addresses) we receive from I/O Kit. For context, I'd like to find out if it affects my Mac App Store receipt validation code in any way. Thank you, – Matthias

Hello, I'm preparing my app Tameno for iOS 18, adding a couple of Control Center widgets. One of them allows users to select their favorite interval. But in the context of my app, only seconds and minutes make sense as a unit value - I don't need milli-pseconds, nor hours. Is there a way restrict these available options that come from a ControlConfigurationIntent? @available(iOS 18.0, iOSApplicationExtension 18.0, *) struct TamenoFavoriteIntervalControlWidgetSetupIntent : ControlConfigurationIntent { static let title: LocalizedStringResource = "cw_FavoriteIntervalSetup" static let isDiscoverable: Bool = false @Parameter(title: "cw_IntervalParameter", defaultValue: 5.0, defaultUnit: .seconds, supportsNegativeNumbers: false) var interval: Measurement<UnitDuration>? @MainActor func perform() async throws -> some IntentResult { .result() } } I am able to restrict it just to seconds or minutes only (by adding unit: .seconds, or unit: .minutes to the @Parameter setup), but I'd really like to offer both. Thank you, Matthias

Hi, my app ScreenFloat can capture screenshots and record the screen (along with system- and microphone audio). It does this in an XPC service. On macOS Sequoia b1-3, recording does not work anymore (although permissions are granted to the app in System Preferences > Privacy & Security). Instead, I keep getting an error that my XPC service can access this computer's screen and audio. (of course, that's the point!) First of all, the screen is locked when the warning appears, clicks anywhere on the screen are not recognized. I have to hit Escape (or wait about a minute, at which point it resolves itself), to be able to click anywhere. Clicking on Continue To Allow doesn't do anything, either. The warning just re-appears every time. Do I need to add a new entitlement to my main app or the XPC service, or any new NSUsage strings to the InfoPlist.strings? How can I resolve this? Thank you, Matthias

FeedbackID: FB13636921 I'm using /usr/sbin/screencapture -v -x -C -k -R 0,0,500,500 /path/to/a/movfile/in/a/folder/in/my/apps/sandbox/Group/Container in my app to allow users to capture screenshots and recordings.

Hello. I'm trying to change my SwiftUI Mac app icon's menu in the Dock, using the NSApplicationDelegate's applicationDockMenu(_ : ) function. However, it does not work: The delegate function is only called once, randomly after launch, and then never again, and it will not show any items in that menu I return. When I right-click the app in the Dock, only the macOS-supplied items are shown, and my App delegate function is not called. Here's the code I use inside my NSApplicationDelegate: func applicationDockMenu(_ sender: NSApplication) -> NSMenu? { let men = NSMenu() print("applicationDockMenu called") var it = NSMenuItem(title: "Test1", action: #selector(test(_:)), keyEquivalent: "") it.target = self men.addItem(it) it = NSMenuItem(title: "Test2", action: #selector(test(_:)), keyEquivalent: "") it.target = self men.addItem(it) return men } @objc func test(_ sender: NSMenuItem) { print("application dock menu custom item called") } Is there a SwiftUI modifier I should be using instead of the NSApp delegate method, or is this just not supported at this time in SwiftUI Mac apps? Thank you, - Matthias

Using the screencapture CLI on macOS Sonoma 14.0 (23A344) results in a 72dpi image file, no matter if it was captured on a retina display or not. For example, using screencapture -i ~/Desktop/test.png in Terminal lets me create a selective screenshot, but the resulting file does not contain any DPI metadata (checked using mdls ~/Desktop/test.png), nor does the image itself have the correct DPI information (should be 144, but it's always 72; checked using Preview.app). I noticed a (new?) flag option, -r, for which the documentation states: -r Do not add screen dpi meta data to captured file. Is that flag somehow automatically set? Setting it myself makes no difference and obviously results in a no-dpi-in-metadata and wrong-dpi-in-image file. The only two ways I got the correct DPI information in a resulting image file was using the default options (forced by -p): screencapture -i -p, and by making the capture go to the clipboard screencapture -i -c. Sadly, I can't use those in my case. Feedback filed: FB13208235 I'd appreciate any pointers, Matthias
