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)? FB15513599 import SwiftUI struct ContentView: View { @State private var showEditItem = false var body: some View { VStack { VStack { Text("Instructions to reproduce the crash") .font(.title) .padding() Text(""" 1. Click on "Toggle Item" 2. In the menu go to File > New Window 3. In new window, click on "Toggle Item" """) } .padding() Button { showEditItem.toggle() } label: { Text("Toggle Item") } } .padding() .toolbar(id: "main") { ToolbarItem(id: "new") { Button { } label: { Text("New…") } } if showEditItem { ToolbarItem(id: "edit") { Button { } label: { Text("Edit…") } } } } } }

Recently, we have adapted the passkey function on the Mac, but we always encounter the error message "Unable to verify the web credentials association of xxx with domain aaa. Please try again in a few seconds." We can confirm that https://aaa/.well-known/apple-app-site-association has been configured and is accessible over the public network. Additionally, the entitlements in the app have also been set with webcredentials:aaa. This feature has been experiencing inconsistent performance. When I restart my computer or reinstall the pkg, this feature may work or it may still not work. I believe this is a system issue. Here is feed back ID: FB20876945 In the feedback, I provided the relevant logs. If you have any suggestions or assistance, please contact me. I would be extremely grateful!

I built a couple of app intents for macOS, which generally work great. However, I'm struggling with configuring an app intent that takes a parameter, so that it doesn't require the app to launch before presenting people with the list of options. If the app is running and I run the intent in Spotlight, I can see the message defined by the intent's parameterSummary and I can select a parameter from the list of entities. If the app is not running, it is launched first and only then the intent message fully populates in Spotlight and allows parameter selection. What I've tried: Support background or deferred mode in the intent. Conformed the entities to IndexedEntity. Conformed the entity query to EnumerableEntityQuery, implementing suggestedEntities and allEntities. Conformed the entity query to EntityStringQuery. Donated the intent to Spotlight on app launch. Donated the entities to Spotlight on app launch, both using indexSearchableItems and indexAppEntities. Not sure if both are required or if the latter is just a more convenient version of the former. Do I have to conform to or implement something else? Do I need to work with an app intent extension? If so, would I put all app intent code into the extension instead of the main app? Is this a system bug I should file?

Hi everyone, My MBP keeps waking from sleep every night to perform Calendar maintenance, although all UI settings that seem related are turned off (Calendar: manual refresh, time to travel = OFF, Clock: automatic time & date = OFF, Automatic Time Machine backup = OFF) Does anyone know how to stop this?

HealthKit is currently not supported on macOS nor tvOS, despite being supported by visionOS. Support for macOS was last asked about[1] here in 2018. My goal is to display interactive data visualisations over workouts collected in HealthKit on macOS. Will this be possible to do in the near future using HealthKit directly? If not, can I somehow read the information from an iPhone and display it on the mac? Cheers, Rodrigo [1] https://developer.apple.com/forums/thread/94937

I have Mac apps that embed “Helper Apps” inside their main bundle. The helper apps do work on behalf of the main application. The helper app doesn’t show a dock icon, it does show minimal UI like an open panel in certain situations (part of NSService implementation). And it does make use of the NSApplication lifecycle and auto quits after it completes all work. Currently the helper app is inside the main app bundle at: /Contents/Applications/HelperApp.app Prior to Tahoe these were never displayed to user in LaunchPad but now the Spotlight based AppLauncher displays them. What’s the recommended way to get these out of the Spotlight App list on macOS Tahoe? Thanks in advance.

When I compiled my legacy project with Tahoe's macOS 26 SDK, NSRulerViews are showing a very different design: Under prior macOS versions the horizontal and verrical ruler's background were blurring the content view, which was extending under the rulers, showing through their transparency. With Tahoe the horizontal ruler is always reflecting the scrollview's background color, showing the blurred content view beneath. And the vertical ruler is always completely transparent (without any blurring), showing the content together with the ruler's markers and ticks. It's difficult to describe, I'll try to replicate this behavior with a minimal test project, and probably file a bug report / enhancement request. But before I take next steps, can anyone confirm this observation? Maybe it is an intentional design decision by Apple?

Simply opening Simulator app (26.0) causes high CPU usage on macOS Tahoe (26.1). ReportCrash process usage is very high throughout and causes the system to heat up pretty soon. Looking into Console app for the logs found MercuryPosterExtension process is keep on crashing. (Check under Crash Reports) simctl Diagnose https://download.developer.apple.com/OS_X/OS_X_Logs/simctl_Diagnose_Logging_Instructions.pdf Share the Simulator Diagnose report while reporting, Thanks. I have raised a ticket/feedback with Apple. I request all of you to raise one too so this gets fixed soon. Apple Feedback Assistant - FB20985249

SwiftUI’s Menu is used also to display view controls like pop-up buttons. However, in such cases, its content is evaluated at the moment the button itself appears, although it’s not required until the menu is actually opened. Additionally, since the menu content isn’t re-evaluated when opened, if the content is dynamically generated, there could be a discrepancy between the actual state and the displayed state depending on the timing. Considering these points, I’d like to delay generating the menu content until the moment it’s actually opened. Is there a way to delay the evaluation and generation of the Menu’s content until the moment its contents are displayed? Note: I'd like to know about using it within a macOS app.

When I startAdvertising, my localName is long, more than 8 bytes. like @"123456789".    [_peripheralManager startAdvertising:@{             CBAdvertisementDataLocalNameKey: @"123456789",             CBAdvertisementDataServiceUUIDsKey: @[[CBUUID UUIDWithString:@"bbbb14c7-4697-aaaa-b436-d47e3d4ed187"]]             }]; When running on macOS 11.x though localName exceeds 8 bytes. But it can still be scanned. {   kCBAdvDataIsConnectable = 1;   kCBAdvDataLocalName = 123456789;   kCBAdvDataRxPrimaryPHY = 0;   kCBAdvDataRxSecondaryPHY = 0;   kCBAdvDataServiceUUIDs =   (     "BBBB14C7-4697-AAAA-B436-D47E3D4ED187"   );   kCBAdvDataTimestamp = "680712553.800874";   kCBAdvDataTxPowerLevel = 12; } But running after macOS 12.x, if localName exceeds 8 bytes, it will be completely ignored. In the scanned data, localName is empty. {   kCBAdvDataIsConnectable = 1;   kCBAdvDataRxPrimaryPHY = 0;   kCBAdvDataRxSecondaryPHY = 0;   kCBAdvDataServiceUUIDs =   (     "BBBB14C7-4697-AAAA-B436-D47E3D4ED187"   );   kCBAdvDataTimestamp = "680712744.108894";   kCBAdvDataTxPowerLevel = 12; } On macOS11.x, SCAN_RSP is utilized if localName exceeds 8 bytes, while on macOS12.x, SCAN_RSP is always empty. Why are there differences between macOS11.x and macos12.x, is there any documentation? What is the maximum limit for localName? (On macOS 11.x, I verified it was 29 bytes Are there other ways to broadcast longer data? Does anyone know why? This has bothered me for a long time...

I'm working on an application for viewing AMF models on macOS, using RealityKit. AMF supports several different ways to color models, including per-vertex color (where the color of a triangle is interpolated from vertex to vertex) as well as per-face color (where the color of the triangle is the same across the entire face). I'm trying to figure out how to support those color models using a RealityKit mesh. Apple's documentation (https://developer.apple.com/documentation/realitykit/modifying-realitykit-rendering-using-custom-materials) talks about per-vertex colors, but I haven't found a way to create a mesh that includes per-vertex colors, other than use a texture map (which might be the correct solution). Can someone give me some pointers?

I'm looking for clarification on a SwiftUI performance point mentioned in the recent Optimize your app's speed and efficiency | Meet with Apple video. (YouTube link not allowed, but the video is available on the Apple Developer channel.) At the 1:48:50 mark, the presenter says: Writing a value to the Environment doesn't only affect the views that read the key you're updating. It updates any view that reads from any Environment key. [abbreviated quote] That statement seems like a big deal if your app relies heavily on Environment values. Context I'm building a macOS application with a traditional three-panel layout. At any given time, there are many views on screen, plus others that exist in the hierarchy but are currently hidden (for example, views inside tab views or collapsed splitters). Nearly every major view reads something from the environment—often an @Observable object that acts as a service or provider. However, there are a few relatively small values that are written to the environment frequently, such as: The selected tab index The currently selected object on a canvas The Question Based on the presenter's statement, I’m wondering: Does writing any value to the environment really cause all views in the entire SwiftUI view hierarchy that read any environment key to have their body re-evaluated? Do environment writes only affect child views, or do they propagate through the entire SwiftUI hierarchy? Example: View A └─ View B ├─ View C └─ View D If View B updates an environment value, does that affect only C and D, or does it also trigger updates in A and B (assuming each view has at least one @Environment property)? Possible Alternative If all views are indeed invalidated by environment writes, would it be more efficient to “wrap” frequently-changing values inside an @Observable object instead of updating the environment directly? // Pseudocode @Observable final class SelectedTab { var index: Int } ContentView() .environment(\.selectedTab, selectedTab) struct TabView: View { @Environment(\.selectedTab) private var selectedTab var body: some View { Button("Action") { // Would this avoid invalidating all views using the environment? selectedTab.index = 1 } } } Summary From what I understand, it sounds like the environment should primarily be used for stable, long-lived objects—not for rapidly changing values—since writes might cause far more view invalidations than most developers realize. Is that an accurate interpretation? Follow-Up In Xcode 26 / Instruments, is there a way to monitor writes to @Environment?

FaceTime’s screen-share audio balance is insanely absurd right now. Whenever I share media, the system audio that gets sent through FaceTime is a tiny whisper even at full volume (or even when connected to my speaker or headphones). The moment anyone on the call makes any noise at all, the shared audio ducks so hard it disappears, while the voice (or rustling or air conditioning noise) spikes to painful levels. It’s impossible to watch or listen to anything together. Also, the feature where FaceTime would shrink to a square during screen-sharing has been completely removed. That was a good feature and I'm really confused why it's gone. Now, the FaceTime window stays as a long rectangle that covers part of the content I'm trying to share (unless I do full screen tile, but then I can't pull up any other windows during the call) and can't be made smaller than about a third of the screen. You can't resize the window or adjust its dimensions, so it ends up blocking the actual media you're trying to watch. Here are some feature requests/fixes that would greatly improve the FaceTime screen-share experience: Option to adjust the shared media volume independently of call audio. Disable/toggle the extreme automatic audio docking while screen-sharing Reintroduce the minimized “floating square” mode or allow full manual resizing and repositioning of the FaceTime window during screen-share sessions. Overall, this setup makes FaceTime screen-sharing basically unusable. The audio balance is so inconsistent that it’s easier to switch to Zoom or Google Meet, which both handle shared sound correctly and let you move the call window out of the way. Until these issues are fixed, there’s no practical reason to use FaceTime for shared viewing at all.

On macOS, I get a system popup when running UI tests in GitHub saying: “bash” is requesting to bypass the system private window picker and directly access your screen and audio. How can I prevent these login and screen access popups from appearing during automated UI tests? Is there an official setup or configuration for running IntelliJ UI tests in CI environments (macOS, Linux, Windows) to avoid such dialogs? My builds run in GitHub Actions VMs, so I can’t manually grant these permissions, and they block the tests.

It's quite common for app bundles to be distributed in .zip files, and to be stored on-disk as filesystem-compressed files. However, having them both appears to be an edge case that's broken for at least two major releases! (FB19048357, FB19329524) I'd expect a simple ditto -x -k appbundle.zip ~/Applications (-x: extract, -k: work on a zip file) to work. Instead it spits out countless errors and leaves 0 Byte files in the aftermath 😭 Please fix.

Hello, I would like to change the system timezone in macOS, given a timezone identifier in the IANA timezone database. is 'systemsetup -settimezone' the only available tool or API that can be used to change the timezone? I have observed that TimeZone(identifier:) can initialize a TimeZone from any identifier in the tz database, but many identifiers are missing from the list accepted by systemsetup. For example, if the user has set the timezone to "Mumbai - India" in system settings, the timezone identifier returned by 'systemsetup -gettimezone' is Asia/Kolkata, which is not in the list printed by 'systemsetup -listtimezones'. What is the recommended way to map a IANA timezone name (or a TimeZone object) to one of the timezone names accepted by 'systemsetup'?
