I'm writing an app on macOS that stores passwords in the Keychain and later retrieves them using SecItemCopyMatching(). This works fine 90% of the time. However, occasionally, the call to SecItemCopyMatching() fails with errSecAuthFailed (-25293). When this occurs, simply restarting the app resolves the issue; otherwise, it will consistently fail with errSecAuthFailed. What I suspect is that the Keychain access permission has a time limitation for a process. This issue always seems to arise when I keep my app running for an extended period.

I just noticed that when you check the online documentation for Foundation using the delicious Objective-C flavor, some values are no more the expected ones: https://developer.apple.com/documentation/foundation/filemanager/copyitem(at:to:)?language=objc#return-value true if the item was copied successfully or the file manager’s delegate stopped the operation deliberately. Returns false if an error occurred. Considering that a BOOL used to be YES or NO for the last quarter of a century, I have the following question: [Q] What is the idea behind the disturbing changes of the Objective-C documentation?

Without resorting to NSViewRepresentable, is there a view or view modifier in SwiftUI that can create an NSComboButton on macOS? NSComboButton was introduced in macOS 13 and is (relatively) new to AppKit: Apple Developer - NSComboButton I only require support on macOS for this control. Note that this is not to be confused with NSComboBox, which is a completely different control.

The application I'm currently working on uses WebKit. Based on the crash analytics, we have noticed that some of our users are experiencing an unusual behavior in the app's WebKit view with macOS 15.3.2. These errors are reported for this version of the OS. The error in the crash log is a SIGABRT error, but there is no relevant information available to address it. In some crash logs, we found this error: "NSInternalInconsistencyException: Returned WKWebView was not created with the given configuration" but there is not any particular way to address it. Is there a way to identify the cause of this error? Alternatively, has anyone encountered this issue and found a solution?

For my macOS app, I'm trying to change the mouse cursor to a pointing hand while hovering over a specific view. However, when the view is scaled with an animation triggered by hovering (using .scaleEffect() and .animation()), the cursor doesn't change as expected. Is there any workaround to fix this? This is a sample code: struct ContentView: View { @State private var hovering = false var body: some View { VStack { Text("Hover me") .padding() .background(hovering ? Color.blue : Color.gray) .scaleEffect(hovering ? 1.2 : 1.0) .animation(.linear(duration: 0.2), value: hovering) .onHover { hovering in self.hovering = hovering if hovering { NSCursor.pointingHand.push() } else { NSCursor.pop() } } } .frame(width: 200, height: 200) } } This is how it works: As you can see, when the pointer enters the view, the cursor changes momentarily before reverting back to the arrow icon. I also tried using NSTrackingArea with an NSView placed over the view, but it did not solve the issue. It might be that the combination of .scaleEffect() and .animation() is causing a forced cursor reset (possibly related to the use of NSWindow.disableCursorRects() or something similar). However, I'm not entirely sure. Any insights or suggestions would be greatly appreciated. Thanks!

I am trying to make http3 client with Network.framework on Apple platforms. Codes that implement NWConnectionGroup.start with NWListener don't always work with warning below. I assume NWConnectionGroup.newConnectionHandler or NWListener.newConnectionHandler will be called to start connection from the server if it works. nw_protocol_instance_add_new_flow [C1.1.1:2] No listener registered, cannot accept new flow quic_stream_add_new_flow [C1.1.1:2] [-fde1594b83caa9b7] failed to create new stream for received stream id 3 so I tried: create the NWListener -> not work check whether NWConnectionGroup has a member to register or not NWListener -> not work (it doesn't have). use NWConnection instead of NWConnectionGroup -> not work Is my understanding correct? How should I do to set or associate listener with NWConnection/Group for newConnectionHandler is called and to delete wanings? What is the best practice in the case? Sample codes are below. Thanks in advance. // http3 needs unidirectional stream by the server and client. // listener private let _listener: NWListener let option: NWProtocolQUIC.Options = .init(alpn:["h3"]) let param: NWParameters = .init(quic: option) _listener = try! .init(using: param) _listener.stateUpdateHandler = { state in print("listener state: \(state)") } _listener.newConnectionHandler = { newConnection in print("new connection added") } _listener.serviceRegistrationUpdateHandler = { registrationState in print("connection registrationstate") } // create connection private let _group: NWConnectionGroup let options: NWProtocolQUIC.Options = .init(alpn: ["h3"]) options.direction = .unidirectional options.isDatagram = false options.maxDatagramFrameSize = 65535 sec_protocol_options_set_verify_block(options.securityProtocolOptions, {(_: sec_protocol_metadata_t, _: sec_trust_t, completion: @escaping sec_protocol_verify_complete_t) in print("cert completion.") completion(true) }, .global()) let params: NWParameters = .init(quic: options) let group: NWMultiplexGroup = .init( to: .hostPort(host: NWEndpoint.Host("google.com"), port: NWEndpoint.Port(String(443))!)) _group = .init(with: group, using: params) _group.setReceiveHandler {message,content,isComplete in print("receive: \(message)") } _group.newConnectionHandler = {newConnection in print("newConnectionHandler: \(newConnection.state)") } _group.stateUpdateHandler = { state in print("state: \(state)") } _group.start(queue: .global()) _listener.start(queue: .global()) if let conn = _group.extract() { let data: Data = .init() let _ = _group.reinsert(connection: conn) conn.send(content: data, completion: .idempotent) }

I am making a USB attached IoT device that follows the Matter approach to connectivity (IP/mDNS/DHCP). I am having conflicts with it as it appears to MacOS as an Ethernet adapter and this is causing it to be assigned as a "default" route, interfering with routing when my Mac is connected to NAT based WiFi. I'd like to be able to hint to MacOS & iPadOS that this is not a routable private network, the subnet should be respected and a default route should not be assigned to it, otherwise the order of the device connection is used by the IP routing tables and I am concerned my non-routable private network will initialize before Wifi and block NAT based internet connectivity. How can I hint to MacOS/iPadOS "this is not a routable private network, this is not a NAT, do not assign me a default route beyond the subnet I have provided you."

I'll preface by saying I am new to MacOS development. I've struggled with this issue for several days and have nowhere else to go for help. My MacOS app is an Electron build. It needs application-groups entitlement for IPC. But the developer portal, when generating the provisioning profile, always appends "groups." to the start and I am unable to remove it. This renders my provisioning profile invalid and causes my app to be rejected by Transporter because it is not supposed to start with "groups", but with my team identified for MacOS. Maybe I can still use the provisioning profile as is, but I've not found any way to do that. So I'm stuck unable to deliver. Any help with this is appreciated.

I don't understand what permissions need to be given for this code to operate. I cannot seem to work out why I'm not able to see a BSSID. I think I've given sandbox the appropriate permissions AND I've added some to the Target Properties for good measure. Yet, cannot get BSSID. import SwiftUI import CoreWLAN import CoreLocation struct ContentView: View { @State private var currentBSSID: String = "Loading..." var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Current BSSID:") Text(currentBSSID) } .padding() .onAppear(perform: fetchBSSID) } func fetchBSSID() { if let iface2 = CWWiFiClient.shared().interface() { print("✅ Found Wi-Fi interface: \(iface2.interfaceName ?? "nil")") } else { print("❌ No Wi-Fi interface found") } if let iface = CWWiFiClient.shared().interface(), let bssid = iface.bssid() { currentBSSID = bssid } else { currentBSSID = "Not connected" print("✅ BSSID: \(currentBSSID)") } } } #Preview { ContentView() } Output - WifI interface is found but BSSID is not found.

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, trying to upgrade from macOS Sequoia 15.3.2 to 15.4 gives this error. Now I can not boot from internal drive of M1 Air 2020, because it restores 15.4, that does not boot. I can only boot from external USB SSD that has macOS 15.3.2. How I can install back 15.3.2 or alternatively newer macOS to internal drive? I only have one Mac, this M1 Air 2020.

I am developing a React Native app for a health monitoring device that connects via Bluetooth and streams live data on iOS. To ensure the uniqueness of the device, I initially planned to use the MAC address. However, I discovered that iOS does not provide access to the original MAC address due to privacy restrictions. Is there an alternative approach to uniquely identifying a Bluetooth device in iOS? I need a reliable way to distinguish devices while maintaining secure and stable connections. Any insights or best practices on handling this in iOS would be greatly appreciated. Looking forward to hearing your suggestions! If anyone has experience with handling Bluetooth device uniqueness on iOS, please share your insights. Thank you!

C++ code that compiled fine on Xcode 16.2 when targeting macOS 13.3 after upgrading to Xcode 16.3 gives an error that the minimum required target is macOS 13.4 with an error like: `/Applications/Xcode-16.3.0.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.4.sdk/usr/include/c++/v1/__format/formatter_floating_point.h:74:30: error: 'to_chars' is unavailable: introduced in macOS 13.4 unknown 74 | to_chars_result __r = std::to_chars(__first, __last, __value, __fmt, __precision); Here’s example taken directly from (https://en.cppreference.com/w/cpp/utility/format/format): #include <format> #include <iostream> #include <string> #include <string_view> template<typename...

The Apple documentation for C++ feature support explicitly discusses 13.3. https://developer.apple.com/xcode/cpp/ (search for P0067R5 on the page) I haven't tested it, but based on the standard library headers the minimum required iOS version has also been bumped - from 16.3 to 16.5. Am I doing something wrong? Is there a known work-around? Filed feedback: FB17081499

I'm using Swift to verify receipts in myObjective C Mac Application using the following code: @objc class MyAppTransaction: NSObject{ @objc class func checkReceipt() async -> String { do { let verificationResult = try await AppTransaction.shared switch verificationResult { case .verified(_): return "VERIFIED" case .unverified(_, _): return "NO RECEIPT" } } catch { return "ERROR" //(StoreKit.StoreKitError) unknown } } } Starting today with my upgrade to Sequoia 15.4 and XCode 16.3 receipt validation is broken. The function is going to the catch and returning "ERROR" I can't set a break point in the do {} but if I set one at the return "ERROR", in the debugger error = (StoreKit.StoreKitError) unknown. the Compiler logs an error:Failed to parse AppTransaction: missingValue(for: [StoreKit.AppTransaction.Key.appTransactionID], expected: StoreKit.BackingValue). Reading the developer documentation I can't find anything about these struct members. I tried to use refresh() to get a receipt like I used to with exit(173) but the compiler says refresh () not found. This is extremely troubling because I can't debug my receipt validation code and I don't know if this will happen to my users. Do I just have to trust Apple that my users will have an application with a receipt attached? What can I do?

Summary Recently a number of bugs affecting our Safari extension have been introduced with various Safari 18.X updates. We've submitted feedback for all of these, but most have received no response. We need to raise this to your attention as it has been affecting our developer experience and causing a lot of frustration for our users. It's something that adds a lot of uncertainty for us. These issues affect core web functionalities but seem to be isolated to the Start Page or Extension environments. For example: using window.open, no longer works using window.location.href = ... no longer works Including a tag in our start page causes infinite reloading to occur. registering a content script more than once will crash Safari Details Unable to open new window as as start page extension in Safari 18 FB15879470 What happens: Calling window.open does nothing. This broke our links to our feedback submission, marketing site & help site. When: Nov 18, 2024 - Initial launch of Safari 18 on macOS Status: Open, No response Unable to open app url scheme with window.location.href in start page extension in iOS 18 FB15879596 What happens: Changing the URL in this way does nothing (well actually it does work about 10% of the time). This broke our navigation to in app payment. When: Nov 18, 2024 - Initial launch of Safari 18 on iOS Status: Open, No response New tab extensions broken FB16126043 What happens: Having a tag in your causes an infinite loop of reloading the start page. This broke our entire start page extension. When: Dec 19, 2024 - Safari 18.3 on iOS beta Status: 10 similar tickets found, marked for future OS update. We did get a response and a fix is identified for a future release window.open opens “about:blank” when called from Start Page extension. FB16427985 What happens: calling window.open from the start page opens about blank on iOS 18.3. Similar to the first issue, but slightly different behaviour. This broke our links to our feedback submission, marketing site & help site. When: Jan 30, 2025 - Safari 18.3 Status: Open, No response Registering a content script more than once causes Safari to crash in macOS 15.4 beta FB16831768 What happens: We have an optional content script that we were registering every time it was used. Although somewhat redundant, it was much simpler than checking if one was already registered and tracking if an updated one needed to replace it. This works fine on all other browsers and all prior Safari versions we've released it on. However if a user enables site blocker on the latest version, as soon as they visit any website, our content script registration causes Safari to crash. Essentially preventing users from using Safari until they uninstall our extension. When: Mar 11, 2025 - Safari 18.4 Status: Open, No response In Conclusion Luckily we have been able to isolate and find workarounds for most of these issues so far, but we are not guaranteed to in the future. We are raising this not only to have these issues looked into, but to raise awareness of the rising trend of basic functionality of Safari extensions breaking with Safari updates. We hope that this can influence a shift in your QA & feedback intake practices to ensure these issues are less frequent in the future. We are happy to raise future issues through your provided channels as they are discovered. But to have our feedback ignored and then have to rely solely on workarounds to prevent disruptions to our users' experience is concerning. We submitted this feedback to our developer relations contact, and he suggested we submit a TSI to look into these issues. In response to this, we were advised to post this here.

Hi, Is there a method to hide individual items in System Settings that is not Deprecated? It needs some of the settings set and hidden for the end user. I found the DisabledSystemSettings key however it is marked as Deprecated and does not include all the new items, especially those related to Apple Intelligence. Is there any method other than “Restrictions” that does not hide and only set individual settings ? It needs to hide items in system settings :)

[Q] Has there been a change in macOS 15.3.2 and later that can explain why some UDP traffic is not seen by some Network Extensions when it is in previous macOS minor and major versions?

Howdy, I'm trying to figure out how to replicate the following behavior for our app: The system is able to ascertain that the Mac equivalent of some iOS app is installed locally, and it prevents notifications from being mirrored. However, I am unable to determine how this association is inferred. When I check our iOS app under this prefpane, the switch remains enabled and toggleable—we'd like to act like Slack here. My initial assumption is that an app group containing both the Mac and iOS apps can be used to create the association; however, I would like to confirm that this is indeed the case before doing so. I'm not terribly confident about this. Details: The bundle identifiers of both apps do not match. This also applies to Slack; its iOS app is com.tinyspeck.chatlyio while its Mac app is com.tinyspeck.slackmacgap. In our case, the iOS app's identifier is like com.company.app while the Mac app's identifier is com.company.app.desktop. Both apps are signed with certificates that have matching team identifiers. The com.apple.developer.team-identifier entitlement is present on the Mac app. The Mac app shares a keychain access group with the iOS app. The Mac app is not sandboxed. The Mac app is an Electron app. The Mac app does not use APNs. It sends notifications "locally". I currently only have the iOS app installed on my iPhone via TestFlight, if that matters. Notification mirroring does work, but we'd like to forcibly disable this by associating the apps together. To my knowledge, the iOS app makes use of both a UNNotificationServiceExtension and a UNNotificationContentExtension. The iOS app currently doesn't have an assigned category (at least in Xcode). The Mac app is currently miscategorized as a developer tool (LSApplicationCategoryType = "public.app-category.developer-tools";), but that should be fixed. (Redacted) bundle information for the Mac app: CFBundleDisplayName = App; CFBundleExecutable = "App Desktop"; CFBundleName = App; Note that our CFBundleExecutable differs from the bundle's display name/name because we're currently migrating our users to a new version of the app that they'd likely want to live alongside the new one. The filename of the bundle itself is, similarly, App Desktop.app. For the iOS app, to my knowledge, the CFBundleName and CFBundleDisplayName are App.
