On macOS 26.1 (25B78) I can't give Full Disk Access to sshd-keygen-wrapper. Now my Jenkins jobs do not work because they do not have the permission to execute the necessary scripts. Until macOS 26.1 everything worked fine. I restarted the machine several times and tried to give access from Settings -> Privacy & Security -> Full Disk Access but it just does not work. I tried logging with ssh on the machine and executing a script but again nothing happened.

I made a new app icon with Icon Composer, and added it to my Xcode project. In the built app, I see AppIcon.icon next to the old AppIcon.icns. But Tahoe is not showing the new icon. Is this because Tahoe has cached the old icon somewhere, and if so, is there some way to make it refresh?

Using SwiftUI on macOS, how can I add a toolbar item on the right-most (trailing) edge of the window's toolbar when an Inspector is used? At the moment, the toolbar items are all left-of (leading) the split view tracking separator. I want the inspector toolbar item to be placed similar to where Xcode's Inspector toolbar item is placed: always as far right (trailing) as possible. NavigationSplitView { // ... snip } detail: { // ... snip } .inspector(isPresented: $isInspectorPresented) { InspectorContentView() } .toolbar { // What is the correct placement value here? ToolbarItem(placement: .primaryAction) { Button { isInspectorPresented.toggle() } label: { Label("Toggle Inspector", systemImage: "sidebar.trailing") } } } See the attached screenshot. When the InspectorView is toggled open, the toolbar item tracks leading the split view tracking separator, which is not consistent with how Xcode works.

Ich habe Tahoe 26.2. installiert und bekomme nun keine Verbindungen zu externen Geräten (Keyboard, Synthesizer). KI gefragt und Antwort bekommen: Tahoe ist keine macOS-update und existiert nicht. Was ist die Wahrheit?

Hi, I have started facing an issue with Xcode since updating to macOS 26.1. The debugger is not stopping at breakpoints in Objective-C code, however breakpoints in Swift file are working fine. I am using Xcode 16.4. For breakpoints in Objective-C files I have started to get this message since the OS update - 'Xcode won't pause at this breakpoint because it has not been resolved.' I have already tried cleaning derived data and build folder. I do not want to upgrade to Xcode 26. Could someone help with the fix? Thanks

I am trying to set an image as the background in the window of a DMG. The image is: PNG file; 144x144 resolution; 1138x574 size. In macOS Tahoe, the image is added by: selecting the DMG window; opening the "Show View Options" dialog; clicking on "Picture"; dragging the image file to the small square box labelled "Drag image here"; closing "Show View Options" dialog. The DMG is then ejected. In Disk Utility, the image file is converted to "Read Only image (UDRO)". The converted image file is opened and the background image is visible. The image file is then copied to a MacBook running macOS 12 Monterey and opened. The background image is NOT shown. The image file is copied to a Mac mini running macOS 14 Sequoia and opened. The background image is NOT shown. Have read past online discussions in which it was explained that an image file called "background" should be inside a hidden folder called ".background". The above procedure did not do that. Is that old advice still correct for macOS Tahoe ? Has Tahoe somehow broken the method used for setting the background of a Window ? Is the method used in Tahoe different to past versions of macOS ? If so, is there a way of maintaining compatibility with old versions of macOS ? Is there any documentation on how to set the background image of a DMG window which might explain this behaviour ?? Thanks.

I'm trying to put a sub menu inside the context menu using the NSExtensionFileProviderActions in info.plist. Which should look like this image below I have been trying to use FPUIActionExtensionViewController for doing this task but I havent got any context menu like above. But still doing that does seem to complicate the task more. Is there a simpler way to do this task, like doing it within the info.plist so I dont have to complicate the task by creating a view controller. ?

In trying to convert some Objective-C to Swift, I have a subclass of NSWindowController and want to write a convenience initializer. The documentation says You can also implement an NSWindowController subclass to avoid requiring client code to get the corresponding nib’s filename and pass it to init(windowNibName:) or init(windowNibName:owner:) when instantiating the window controller. The best way to do this is to override windowNibName to return the nib’s filename and instantiate the window controller by passing nil to init(window:). My attempt to do that looks like this: class EdgeTab: NSWindowController { override var windowNibName: NSNib.Name? { "EdgeTab" } required init?(coder: NSCoder) { super.init(coder: coder) } convenience init() { self.init( window: nil ) } } But I'm getting an error message saying "Incorrect argument label in call (have 'window:', expected 'coder:')". Why the heck is the compiler trying to use init(coder:) instead of init(window:)?

In my impression, this issue has been around for years. In the Mac App Store, the app description is collapsed by default. After clicking "More" to expand it, the last few lines of the description are always cropped. It seems that the more content there is, the more content gets cropped. The following screenshots are from the same app, one with the system language set to Chinese and the other to English.

Since upgrading to Mac OS 10.5 Beta-2, daemons launched with launchctl are failing to open Desktop/Documents/Downloads files and folders even in read mode with an error "Operation not permitted".Does anyone facing this issue?

While preparing my app for Declared Age Range capability usage, I've noticed a weird behaviour: the same code works for iOS, but not for macOS. My project uses same target for both platforms, so the capability is enabled for both platforms. The business logic layer is also shared across between platforms. Both UI layers are writter in SwiftUI. The iCloud account used for testing on iOS and macOS devices is the same, so even the consent is shared across both devices. While requestAgeRange(ageGates:) seems to work just fine for iOS app, for macOS app it always throws Not available error (DeclaredAgeRange.AgeRangeService.Error.notAvailable) Am I missing something? Could the API be somehow unavailable for macOS? Should I use AgeRangeService.shared.requestAgeRange(ageGates:in:) for macOS instead of SwiftUI's @Environment-based approach? Also, after giving permission, is there a way to actually revoke it? In Age Range for Apps menu I can only view the list of apps that have my consent to share my age range, but not the ability to revoke it.

Hi everyone, I'm new to building apps on Swift and recently I've been wondering how does Apple get this blur effect behind the control center on Mac OS Tahoe. I think it would be nice to use in an app that I'm making but I can't seem to find it in the docs. Is it available through AppKit? I would appreciate some help on this

I'm having a problem on macOS 26 that has not happened on previous macOS versions. When I call guard url.startAccessingSecurityScopedResource() else { return } try url.bookmarkData(options: [.withSecurityScope]) with url being "file:///", I get an error Error Domain=NSCocoaErrorDomain Code=256 "File descriptor doesn't match the real path." Given that Google returns 0 results on this error, I suppose this is a macOS 26 novelty. (The bookmark data created before upgrading to 26 resolve well). Does anyone already met this or have an idea on how to get around it? The app is a file manager, so having bookmarked access to "/" is crucial.

I noticed, that even though my AutoFill Credential Provider Extension works with Safari for both Passwords and Passkeys, it doesn't work in context menus inside arbitrary textfields, meanwhile the same is true for the Apple Passwords app. This is a great hit to AutoFill productivity, as my extension is unable to fill textfields by just going to the context menu and clicking AutoFill > Passwords.. Is this a feature only available to Apple via private APIs, or is this something I can interface with? I checked and the Passwords app does use some undocumented but non-private entitlements: [Key] com.apple.authentication-services.access-credential-identities [Value] [Bool] true I also checked the responsible executable for some hints (AutoFillPanelService) however found nothing that would lead me to believe this is a public extension point. Another idea I had was trying to use a macOS Service for this, however Services in the "General" category won't show up in any context menu, only in the Application's Main Menu.

Running Tahoe 26.1 in a virtual machine, I can't sign into my Apple account. There is an error message saying "Could not communicate with the server." Internet access otherwise seems to be working in the VM. I tried both UTM and VirtualBuddy. Is this supposed to work?

When I pass a file path url of a file in iCloud Drive to -[NSWorkspace openURLs:withApplicationAtURL:configuration:completionHandler:], it fails. There is no exception, and the completion handler isn't called. This is in a sandboxed app on macOS 26.1. NSWorkspaceOpenConfiguration* config = NSWorkspaceOpenConfiguration.configuration; config.activates = YES; config.promptsUserIfNeeded = YES; NSLog(@"performDrag 2 with %@", filePathObs); [NSWorkspace.sharedWorkspace openURLs: filePathObs withApplicationAtURL: appURL configuration: config completionHandler: ^(NSRunningApplication * _Nullable app, NSError * _Nullable error) { NSLog(@"performDrag 3"); if (error != nil) { NSLog(@"%@\n%@", error, filePathObs); } NSLog(@"complete performDrag"); }]; NSLog(@"performDrag 4"); In the debug log, the performDrag 2 and performDrag 4 messages appear. I also looked in the Console log, but the only messages that mention my app don't mean anything to me.

I'd like to set my macOS app written in Swift as default app when opening .mp4 file. I think I can do it with setDefaultApplication(at:toOpen:completion:). https://developer.apple.com/documentation/appkit/nsworkspace/3753002-setdefaultapplication However, permission error occurs when I use it. The error is: Error Domain=NSCocoaErrorDomain Code=256 "The file couldn’t be opened." UserInfo={NSUnderlyingError=0x6000031d0150 {Error Domain=NSOSStatusErrorDomain Code=-54 "permErr: permissions error (on file open)"}} I tried to give my app full-disk access, but it didn't work. I also tried to use setDefaultApplication(at:toOpenFileAt:completion:), then it works with no error, but it effects on only one file. What I want to do is to set my app as default app of all .mp4 files. How do I achieve this? My code is like below: let bundleUrl = Bundle.main.bundleURL NSWorkspace.shared.setDefaultApplication(at: bundleUrl, toOpen: .mpeg4Movie) { error in print(error) } Thank you.

We use File Provider Extension in our main app, and it is working fine. We always call "NSFileProviderManager.add(_:completionHandler:)" function to start the extension, and "NSFileProviderManager.disconnect(reason:options:completionHandler:)" to temporarily quit the extension with the reason which will be shown in the Finder at the top of the FP domain folder. But sometimes, when the main app calls the above functions, the following issue cases occur, and the extension does not start/stop: The completionHandler function doesn't get called (As we noticed, we waited for 2 minutes. Then, we restarted the main app.) One of the following errors returned: i) "The application cannot be used right now", ii) "Couldn't communicate with the helper application", iii) "No valid file provider found with identifier" Here, the important thing is that restarting the main app once or twice clears the issue, and the extension starts. But it is frustrating to restart the app each time we get this issue. We want to know the following things: Why and when do the above issues occur? Why do they occur only sometimes, and how does the app restart clear the issue? How do we resolve them without restarting the main app? This has become a critical issue, so a detailed explanation would be greatly appreciated. TIA.

Hi, We use Flat package installers (.pkg based installers) to install our applications on macOS. In macOS 26.1, installation is failing with the error Unable to use PK session due to incompatible packages. Terminating. 2025-11-03 14:22:36+05:30 Admin-3 installer[1160]: Install failed: The Installer could not install the software because there was no software found to install. Same installer package is working on macOS 26. Any help is greatly appreciated.

Hi everyone, I am trying to generate an .ipa file for my .NET MAUI (net9.0-ios) application, but every attempt fails with the same codesigning error. I have tried multiple approaches, including building from Windows paired to macOS, and directly building through the macOS terminal, but nothing is working. Below are the exact steps I followed: Steps I Performed Generated the Apple Development certificate using Keychain Access on macOS. Added that certificate into my developer account and created the corresponding provisioning profile. Created an App ID, attached the App ID to the provisioning profile, and downloaded it. Added the provisioning profile into Xcode. Verified that the certificate is correctly visible in Keychain Access (private key available). Attempted to build/publish the MAUI app to generate the .ipa file. Issue Whenever I run the publish command or build via Windows/macOS, codesigning fails with the following error: /usr/bin/codesign exited with code 1: Frameworks/libSkiaSharp.framework: replacing existing signature Warning: unable to build chain to self-signed root for signer "Apple Development: Created via API (8388XAA3RT)" Frameworks/libSkiaSharp.framework: errSecInternalComponent Failed to codesign 'PCS_EmpApp.app/Frameworks/libSkiaSharp.framework': Warning: unable to build chain to self-signed root for signer "Apple Development: Created via API (8388XAA3RT)" PCS_EmpApp.app: errSecInternalComponent Build eventually fails with: Build failed with 4 error(s) and 509 warning(s) Environment .NET: 9.0 MAUI: latest tools Xcode: 26.0.1 macOS: 26.0.1 Building for ios-arm64 (device) What I suspect It looks like the signer certificate might not be trusted, or the certificate chain cannot connect to an Apple root CA. But the certificate was created using the Developer website and appears valid. Need Help With Why is codesign unable to build the certificate chain? Do I need a different type of certificate? (App Store / Distribution vs Development?) Is there any special configuration required for MAUI apps using native frameworks like libSkiaSharp.framework? How can I successfully generate the .ipa file? Any guidance will be greatly appreciated. Thank you!
