Given that we can't use isEligibleForAgeFeatures property on macOS, the documentation states that In macOS, isEligibleForAgeFeatures returns false because the system doesn’t require Age Assurance for the person or device. However, you can still call requestAgeRange in macOS to get the declared age range. But in unsuitable region the requestAgeRange request always returns DeclaredAgeRange.AgeRangeService.Error.notAvailable which is vague, as it might stand for API being unavailable just as well as "You receive this error when the system prompts a person and they decide not to share their age range with your app. ", as per documentation. Unfortunately, this error fires immediately instead of showing any kind of prompt for user, so the description is definitely wrong (or incomplete) in here. Possible solutions: expand Error cases to separate not available API and not available response expand isEligibleForAgeFeatures to properly support macOS Moreover, unlike iOS, there is still no usable tool or algorithm to test given feature for macOS (mock region, mock age, mock source of approval, revoke declared range, etc). Now I get a review with rejection, stating that I don't have age verification mechanisms present in my app. Also I found out that after filling the App Information regarding Age Ratings it spreads to all fresh releases, so even though my newest macOS release doesn't contain age verification mechanisms yet, it should, as iOS release has got this functionality up and running already and I had to check this when filling Age Ratings questionnaire. Now I'm stuck between removing this capability from App Information, so the macOS release can pass and stalling macOS releases until there is a proper usable API to implement Declared Age Range verification properly (at least the same way as on iOS). How should I properly develop and test this feature for macOS before releasing it publicly?

Dear Apple, while implementing Declared Age Range API in my app, I've noticed a mistake in documentation: the isEligibleForAgeFeatures property is marked 26.0+ in documentation, but 26.2+ in Xcode, which ultimately leads to inability to use it with OS below 26.2. Moreover, I'm thoroughly confused by this quote from documentation: This flag returns true on iOS and iPadOS based on a person’s eligibility and always returns false on macOS. It leads me to two questions: Is it possible to use Declared Age Range API for macOS apps? Will it be possible to use it in future? Will there be any changes regarding this matter in a meantime (especially after Jan 1st)? If yes - when should we expect these changes? If no - why this API declares macOS 26+ support alongside iOS/iPadOS, if it simply doesn't work for macOS now? As of now, my iOS app works flawlessly with given API (on iOS 26.2) while macOS app returns isEligibleForAgeFeatures = false and requestAgeRange request always throws AgeRangeService.Error.notAvailable. Also, does it mean that one should not use isEligibleForAgeFeatures boolean while implementing Declared Age Range API for apps below iOS 26.2 (I mean 26.0+)? Or implementing given API for iOS 26.2+ is a sufficient way to go? So shouldn't the whole API be marked as 26.2+? The minimum iOS version in my app is 16.0 and minimum macOS version is 13.0 anyway, so the significant part of users is left out of these updates, but the main goal here is legal compliance.

We have a macOS system extension with NETransparentProxyProvider which is able to intercept traffic and handle it. We also wanted to setup few search domains from our network extension. However, unlike PacketTunnelProvider, NEDNSSettings are completely ignored with NETransparentProxyProvider. So whats the best way to setup few DNS search domains when using NETransparentProxyProvider.

This example application crashes when entering any text to the token field with FAULT: NSGenericException: The window has been marked as needing another Update Constraints in Window pass, but it has already had more Update Constraints in Window passes than there are views in the window. The app uses controlTextDidChange to update a live preview where it accesses the objectValue of the token field. If one character is entered, it also looks like the NSTokenFieldDelegate methods tokenField(_:styleForRepresentedObject:) tokenField(_:editingStringForRepresentedObject:) tokenField(_:representedObjectForEditing:) are called more than 10000 times until the example app crashes on macOS Tahoe 26 beta 6. I've reported this issue with beta 1 as FB18088608, but haven't heard back so far. I have multiple occurrences of this issue in my app, which is working fine on previous versions of macOS. I haven't found a workaround yet, and I’m getting anxious of this issue persisting into the official release.

In the attached screenshot, we have an NSSplitViewController with three split view items. The first two are viewController split view items, while the third is an inspector split view item. The NSWindow is configured for full screen content so that the inspector split view items is full height itself. However, when we enable full height content view, AppKit is automatically adding a tracking separator into the toolbar when we don't want one. (Neither of the two split views are sidebars.) This tracking separator is out of place, cannot be dragged itself, and is drawn under the center aligned segmented control. We've tried a multitude of permutations to configure the NSWindow, NSToolbar and NSSplitViewItem but to no avail. Surely we're just missing the magic combo but a lot of the properties appear to be no-ops in macOS 26. How do we use an NSSplitViewController, in a full screen content window, such that we get a full height inspector but we don't get tracking separators for the main split view divider?

I understand this is a known issue, but it’s truly unacceptable that it remains unresolved. Allowing users to customize toolbars is a fundamental macOS feature, and it has been broken since the release of macOS 15. How is it possible that this issue persists even in macOS 15.3 beta (24D5040f)?

Hi, I'm posting a boot crash here. Environment Hardware: Macbook M5 Pro OS Version: macOS 26.3.1 (25D2128) and matching version of KDK from official apple download page Kernel Version: Darwin Kernel Version 25.3.0 Reproducibility: Consistent Here is my panic log --- I truncated one field "SOCDNandContainer" as the original log is too long to post, hitting the size limit. I followed a blog post to boot the development kernel as the ReadMe file from KDK only contains instructions for Intel Macs. https://jaitechwriteups.blogspot.com/2025/10/boot-custom-macos-kernel-on-macos-apple.html I've tried a few 26.2 KDKs before 26.3.1 public launch, and they all showed same errors (26.1 and 26.0 KDKs don't have any development kernel for T8142 chip). Also, I own two fresh M5 Pro, and it is consistent across the machines. The highlight is panic(cpu 8 caller 0xfffffe0050e18010): [Exclaves] $JgOSLogServerComponent.RedactedLogServer.init(logServerNotific:OSLogServerComponent\/OSLogServerComponent_Swift.swift:815: Fatal error: invalid rawValue for TightbeamComponents.RedactedLogSer at PC ... Is this a genuine bug or am I following a wrong guide to boot the development kernel? I don't think the blog is wrong because I'm able to boot the "release" kernel included in the KDK on the same M5 Pro, and the "development" kernel on M4 Mac Mini, using the same routine. Just to be clear, I'm not compiling XNU myself, but am using the ones included in the kit.

The developer payment page is returning a 503 error, preventing me from making the payment. Why is this happening? I need to complete this payment urgently.

I have received a few crash reports for my app "Find Any File" with an assertion failure as follows: assertion failure: "displayTiming != ((void *)0)" -> %lld Googling this turns up nothing, though. I wonder if someone has some insight into why this might happen, and how to prevent it. One reporting user suggests that it happens when my app shows a very long list of items in an NSTableView (>10000 elements). I have 4 reports from 3 users, and the main thread is doing something related to the table view each time, though not the same (the few other threads are all idle): Crash 1, in macOS 14.0 (23A344: Thread 0:: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x182c69400 objc_msgSend + 0 1 AppKit 0x186f15400 -[CALayer(NSViewVisibleRect) NS_viewVisibleRectDidChange] + 40 2 AppKit 0x186900e10 NSViewHierarchyInvalidateVisibleRect + 276 3 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 4 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 5 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 6 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 7 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 8 AppKit 0x1869990e0 -[NSView translateOriginToPoint:] + 164 9 AppKit 0x186984108 -[NSClipView _immediateScrollToPoint:] + 420 10 AppKit 0x186983eb8 -[NSClipView scrollToPoint:] + 184 11 AppKit 0x186998d80 -[NSScrollView scrollClipView:toPoint:] + 84 12 AppKit 0x1869448dc -[NSClipView _scrollTo:animateScroll:flashScrollerKnobs:] + 480 13 AppKit 0x186b65b24 __62-[NSScrollingBehaviorConcurrentVBL _stopGestureScrollTracking]_block_invoke + 192 14 AppKit 0x186e6a6e8 ___NSMainRunLoopPerformBlockInModes_block_invoke + 44 15 CoreFoundation 0x18310b8c0 __CFRUNLOOP_IS_CALLING_OUT_TO_A_BLOCK__ + 28 Crash 2, in macOS 14.1.1 (23B81): Thread 0:: Dispatch queue: com.apple.main-thread 0 CoreFoundation 0x18ba401f4 DYLD-STUB$$_Block_object_assign + 0 1 libsystem_blocks.dylib 0x18b506118 _call_copy_helpers_excp + 80 2 libsystem_blocks.dylib 0x18b505c68 _Block_copy + 376 3 libdispatch.dylib 0x18b641c7c _dispatch_Block_copy + 32 4 libdispatch.dylib 0x18b658df0 _dispatch_source_set_handler + 92 5 CoreFoundation 0x18b99e1e4 __CFRunLoopCopyMode + 540 6 CoreFoundation 0x18b8b7458 CFRunLoopAddObserver + 220 7 AppKit 0x18f0a687c _PerfAddRunLoopObserver + 192 8 AppKit 0x18f87cd60 -[NSApplication(NSEventRouting) _nextEventMatchingEventMask:untilDate:inMode:dequeue:] + 368 9 AppKit 0x18f323318 -[_NSScrollingConcurrentEventMonitor startMonitoring] + 380 10 AppKit 0x18f321df8 -[NSScrollingBehaviorConcurrentVBL _scrollView:trackGestureScrollWithEvent:] + 884 11 AppKit 0x18f2e67f8 -[NSScrollingBehaviorConcurrentVBL scrollView:scrollWheelWithEvent:] + 512 12 AppKit 0x18f241770 forwardMethod + 252 13 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 14 AppKit 0x18f241770 forwardMethod + 252 15 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 16 AppKit 0x18f241770 forwardMethod + 252 17 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 18 AppKit 0x18f241770 forwardMethod + 252 19 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 20 AppKit 0x18fc45880 -[NSCollectionView scrollWheel:] + 180 21 AppKit 0x18f241770 forwardMethod + 252 22 AppKit 0x18f241770 forwardMethod + 252 23 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 24 AppKit 0x18f241770 forwardMethod + 252 25 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 26 AppKit 0x18f241770 forwardMethod + 252 27 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 28 AppKit 0x18f1d27b0 -[NSWindow(NSEventRouting) _reallySendEvent:isDelayedEvent:] + 652 As you can see, there's no code of mine involved at the time of crash.

In SwiftUI for macOS, how do I configure a Picker as a segmented control to have a flexible width? This design pattern is present in Xcode 26 at the top of the sidebar and inspector panel. I can't figure out the combination of view modifiers to achieve a similar look. import SwiftUI struct ContentView: View { @State private var selection = 0 var body: some View { VStack { Picker("", selection: $selection) { Image(systemName: "doc") Image(systemName: "folder") Image(systemName: "gear") Image(systemName: "globe") .frame(maxWidth: .infinity) // Doesn't do anything. } .labelsHidden() .pickerStyle(.segmented) .frame(maxWidth: .infinity) // Doesn't affect segment sizes. Spacer() } } } I want the entire Picker to fill the width and for each segment to be of equal widths. How? In AppKit I would use AutoLayout for the flexible width and NSSegmentedControl.segmentDistribution for the segment widths. Is there a SwiftUI equivalent? macOS 26 / Xcode 26.3

When you have multiple Apps on the Mac which all provide Quicklook extensions for the same file type, then I would assume that if I activate one of these Quicklook extensions in the system settings, this one would be used. But this doesn't seem to be the case. It looks like the macOS just looks the very first extension it can find for a certain file type, and if this Quicklook extension is switched off, the file can not be previewed anymore. The macOS just doesn't bother to look for the other existing quicklook extension for this file, even if this other is enabled. The only option right now to get this other extension to be used by the system would be to completely delete the first App, so its extension is deleted as well. Is this really the way how it is supposed to work? How can this be fixed? Can I tell my users something else than "just delete the other App"?

We are experiencing an issue with ADCertificate auto-renewal on macOS devices enrolled via MDM.

I'd like to create a Quick Look extension for a file type for which a location or region on a Map should be shown as preview. However the MapView would only show a grid without any map. From within the MapKit delegate I can see from the "Error" parameter (a server with this domain can not be found) that this seems to be a network issue. The Quick Look extension seems to have no access to the internet and therefore the MapView can not load any map data. I've then also done some other tests via URLSession, which also only fails with connection errors. I haven't seen any limitations or restrictions mentioned in the API documentation. Is this the expected behavior? Is this a bug? Or am I missing something?

I'm trying to test the update process for an app containing an FSKit module that I'm distributing on the Mac App Store. (I'm also distributing the same app directly with Developer ID, but here I'll focus on App Store because that's the behavior I've been looking at first.) To do that I'm using an internal tester group on TestFlight and then testing an update with TestFlight. Below is the behavior I'm seeing on macOS 15.7.2 (24G325). I've noticed that if an app update is triggered while a disk is mounted using the FSKit extension, the disk is automatically unmounted without warning (FB21287341). That's already undesirable itself in my opinion, but on top of the unmount, there are two other problems: That unmount doesn't seem to be a "clean" unmount and doesn't call functions like synchronize (FB21287688). Now, in my case, my app only provides read-only access, so that doesn't actually matter much in my case. However, I'd imagine if I were to add write access at some point in the future, this would go from "doesn't matter" to "very bad." I've seen a few cases where quitting or crashing the FSModule process while a volume is mounted without actually doing a clean unmount causes a lot of "disk-related actions" (for lack of a better term) to freeze (FB21305906). For example, a use of the mount(8) command or trying to mount a disk at all freezes, and opening Disk Utility stalls on a "Loading disks" spinning indicator. This happens until the Mac is rebooted. I did notice this issue once while testing updates via TestFlight a few times. The same applies if I simply delete the app with Finder instead of updating it. Is there a way to prevent the extension's process from terminating in this case and/or another workaround I could use without waiting for a macOS update to hopefully change this behavior? And does observing this kind of behavior with TestFlight's update behavior suggest the same thing could happen on the App Store with its automatic updates? I'm concerned that pushing an update via the App Store will unexpectedly unmount disks or cause the system-wide issues described in FB21305906 at a random time, which is a pretty big disruption for users.

Mac Pro 2019, Tahoe 26.3, Xcode 26.2 Mac Mini 2023 M2, Tahoe 26.3, Xcode 26.2 On Mac Pro 2019 the app is only Intel while on Mac Mini 2023 M2 it is ARM64 only. Both have Standard Architectures (Apple Silicon, Intel). Both have Build Active Architecture Only is set to No (Debug + Release). Happen for default new projet macOS -> App and Obj-C, Xib. No change to defaults setting except uncheck "Automaticaly manage signing" and "Signing Certificate" set to "Sign to Run Locally" HOWEVER On Mac Pro 2019, BigSur 11.7.10, Xcode 14.10 the application is build Universal ! Why cannot build universal with Tahoe 26.3, Xcode 26.2 ? Can I submit a Mac applcation to App Store Connect with BigSur 11.7.10, Xcode 14.10 ? What are the minimal version of Mac Os and Xcode to submit a Mac applcation to App Store Connect ?

Hello Using a MacBook Pro Intel with macOS 12.7.6 Monterey, I test in Objective-C an event for the option key but it is not working - (void)keyDown:(NSEvent *)event { printf("%s %p\n", __FUNCTION__, self); BOOL altFlag = [event modifierFlags] & NSEventModifierFlagOption; if (altFlag) { // UpdateClass printf("option pressed\n"); } else { printf("option not pressed\n"); } } The same in Swift works fine override func keyDown(with event: NSEvent) { if event.modifierFlags.contains(.option) { print("option pressed") } else { print("option NOT pressed") } } The Obj-C code works fine on a MacBook Air Tahoe 26.3 Any idea why it does not work on the macOS 12.7.6 Intel? Many Thanks Jean

After updating to another beta of High Sierra, my internal hard drive became read-only somehow. I have a user home directory on that and many things have stopped working. I tried re-installing the OS, but it didn't help. I'm out of options by now. Anyone has ideas how can I fix that?

In macOS 26, there is a new property on NSControl called .borderShape. The WWDC 2025-310 video says it can be used to "Override preferred shape of control to suit your design." and that it's available on NSButton, NSPopUpButton and NSSegmentedControl. Is there an equivalent to that property for SwiftUI? For example, given the following SwiftUI code: Button("Eject") { } .borderShape(...) <-- ? How can I apply a .borderShape that would match those on controls created in AppKit? I'm aware that SwiftUI offers a plethora of ways to custom design a button such that it can have rounded corners, but I'm interested in this particular property so that SwiftUI buttons and AppKit buttons in the same app have the same look-and-feel.

On macOS 26.3, Xcode 26.3, why does a labelStyle of titleAndIcon not show both the title and the icon of a label? The label styles iconOnly and titleOnly behave as expected. Picker("Label Demo", selection: $selectedItem) { Label { Text("File") } icon: { Image(systemName: "doc") } Label { Text("Folder") } icon: { Image(systemName: "folder") } } .labelStyle(.titleAndIcon) .pickerStyle(.segmented) Note that there is no icon shown. Placing the .labelStyle modifier in different places has no effect. The icon is correctly shown when the labelStyle is set to .iconOnly. An NSSegmentedControl created with AppKit and presented in an NSViewRepresentable does correctly show titles and icons if configured appropriately. Tested on: macOS 26.3 (25D125) Xcode 26.3 (17C519) A brand new SwiftUI "macOS App" project.

Since the introduction of the siblings / and /System/Volumes/Data architecture, some very basic, critical commands seems to have a broken behaviour ( cp, rsync, tar, cpio…). As an example, ditto which was introduced more than 10 years ago to integrate correctly all the peculiarity of HFS Apple filesystem as compared to the UFS Unix filesystem is not behaving correctly. For example, from man ditto: --rsrc Preserve resource forks and HFS meta-data. ditto will store this data in Carbon-compatible ._ AppleDouble files on filesystems that do not natively support resource forks. As of Mac OS X 10.4, --rsrc is default behavior. [...] --extattr Preserve extended attributes (requires --rsrc). As of Mac OS X 10.5, --extattr is the default. and nonetheless: # ls -@delO /private/var/db/ConfigurationProfiles/Store drwx------@ 5 root wheel datavault 160 Jan 20 2024 /private/var/db/ConfigurationProfiles/Store                            ********* com.apple.rootless 28 *************************** # mkdir tmp # ditto /private/var/db/ConfigurationProfiles tmp ditto: /Users/alice/Security/Admin/Apple/APFS/tmp/Settings: Operation not permitted ditto: /Users/alice/Security/Admin/Apple/APFS/tmp/Store: Operation not permitted # ls -@delO tmp/Store drwx------ 5 root wheel - 160 Aug 8 13:55 tmp/Store                            * # The extended attribute on copied directory Store is empty, the file flags are missing, not preserved as documented and as usual behaviour of ditto was since a long time ( macOS 10.5 ). cp, rsync, tar, cpio exhibit the same misbehaviour. But I was using ditto to be sure to avoid any incompatibility with the Apple FS propriaitary modifications. As a consequence, all backup scripts and applications are failing more or less silently, and provide corrupted copies of files or directories. ( I was here investigating why one of my security backup shell script was making corrupted backups, and only on macOS ). How to recover the standard behaviour --extattr working on modern macOS?
