I’ve been having problems with MacOS builds. I’m making a release Appstore build and uploading it to Testflight. However when running it instantly crashes, and report screen shows the following: Current flow: I sign all files in PlugIns/ (we have a number of .bundle), and I’ve tried combinations of signing with/without --entitlements, as well as with/without --deep. After this I sign Frameworks/GameAssembly.dylib and Frameworks/UnityPlayer.dylib. Again, I’ve tried combinations of with/without --entitlements and --deep, also not signing them at all. After signing PlugIns and frameworks, I sign the .app, also tried this with/without --deep (always with --entitlements). Finally I make a .pkg and upload to Testflight. It’s not the game, as I can make an enterprise version that runs fine. We have some restricted entitlements, such as Apple Arcade. Building from an M1 mac, and architecture is Universal (Intel + ARM). Unity documentation says to use --deep, but Apple documentation highly recommend against it. So basically, my question is, how and in what order should I sign the files? Much obliged!

Hi, I have a file provider based MacOS application where i have a drive added and am trying to download a folder from that drive. The folder has sub folders and large files in it. After some time of download started, i keep getting below error. error: ["The operation could not be completed. Cannot allocate memory", [code: 12, domain: "NSPOSIXErrorDomain"] The download action is triggered via Finder's download icon(cloud icon with down arrow). I am using native URLSession to download the files from server. No third party library is used. What could be the possible reasons for "can not allocate memory" issue?

Hello everyone, I’m facing an issue with running my app on my iPhone, and I’m hoping someone can help. Here’s my situation: I’m using Xcode 14.3.1 on macOS Ventura 13.7.4. My iPhone is running iOS 18.3.2 (Model: iPhone 14 Pro). When I connect my iPhone to Xcode, I get the error: "Could not locate device support files. You may be able to resolve the issue by installing the latest version of Xcode from the Mac App Store or developer.apple.com." I understand that Xcode 14.3.1 only supports up to iOS 16.4, and my iPhone’s iOS 18.3.2 is much newer. Unfortunately, I cannot update my macOS to Sonoma (14.x) due to hardware limitations, so I cannot install a newer version of Xcode (like 15.x or 16.x) that supports iOS 18.3.2. I’ve tried adding device support files manually, but the repositories I found (e.g., iGhibli/iOS-DeviceSupport and JinjunHan/iOSDeviceSupport) only have files up to iOS 16.4 or 17.3, and they don’t work for iOS 18.3.2. Does anyone have the device support files for iOS 18.3.2 (or a close version like 18.3) that I can add to my Xcode 14.3.1 to make it work with my iPhone? Alternatively, does anyone know a reliable source where I can download these files? Any other suggestions to resolve this issue without upgrading my macOS would be greatly appreciated! Thank you in advance for your help! [Your Name or Username]

Hello I was wondering if there is a way to ensure that a C program I am writing can only write to 1 virtual page. I am trying to test how space efficient different Mallocs are and I need a way to ensure that the OS will not try to swap out pages making the space efficiency test pointless. I am on Mac OS Sonoma v14.5.

My audio and MIDI sequencer application consumes about 600 % of CPU power with 10 different instruments during playback. While idle approximately 100%. What is the maximum of CPU power that an application can consume? Are there any limits and could they be modified? I am asking because if I add more instruments the real-time behaviour gets bad at 700 % of CPU power. I have got following HW: MacBook Pro 14-inch, Nov 2024 Apple M4 Pro 24 GB

I am looking at some logs that I collected through sysdiagnose and I notice several messages of the form: ... fault 2025-03-05 01:12:04.034832 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=86764 AUID=502> and <anon<java>(502)(0) pid=86764> fault 2025-03-05 01:15:05.829696 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88001 AUID=502> and <anon<java>(502)(0) pid=88001> fault 2025-03-05 01:15:06.047003 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88010 AUID=502> and <anon<java>(502)(0) pid=88010> fault 2025-03-05 01:15:06.385648 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88012 AUID=502> and <anon<java>(502)(0) pid=88012> fault 2025-03-05 01:15:07.135896 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88019 AUID=502> and <anon<java>(502)(0) pid=88019> fault 2025-03-05 01:15:07.491316 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88021 AUID=502> and <anon<java>(502)(0) pid=88021> fault 2025-03-05 01:15:07.542102 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88022 AUID=502> and <anon<java>(502)(0) pid=88022> fault 2025-03-05 01:15:07.803126 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88025 AUID=502> and <anon<java>(502)(0) pid=88025> fault 2025-03-05 01:15:59.774214 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88568 AUID=502> and <anon<java>(502)(0) pid=88568> fault 2025-03-05 01:16:00.142288 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88572 AUID=502> and <anon<java>(502)(0) pid=88572> fault 2025-03-05 01:16:00.224019 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88573 AUID=502> and <anon<java>(502)(0) pid=88573> fault 2025-03-05 01:16:01.180670 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88580 AUID=502> and <anon<java>(502)(0) pid=88580> fault 2025-03-05 01:16:01.879884 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88588 AUID=502> and <anon<java>(502)(0) pid=88588> fault 2025-03-05 01:16:02.233165 +0000 runningboardd Two equal instances have unequal identities. <anon<java>(502) pid=88589 AUID=502> and <anon<java>(502)(0) pid=88589> ... What's strange is that each of the message seems to say that it has identified two instances with unequal identities and yet it prints the same process for each such message.

Yet the message isn't clear why the same process would have two different identities. The type of this message is "fault", so I'm guessing that this message is pointing to some genuine issue with the executable of the process. Is that right? Any inputs on what could be wrong here? This is from a 15.3.1 macosx aarch64 system. On that note, is runningboardd the process which is responsible for these identity checks?

In context of entitlements that are applicable on macos platform, I was discussing in another thread about the com.apple.security.cs.allow-unsigned-executable-memory and the com.apple.security.cs.allow-jit entitlements in a hardened runtime https://developer.apple.com/forums/thread/775520?answerId=827440022#827440022 In that thread it was noted that: The hardened runtime enables a bunch of additional security checks. None of them are related to networking. Some of them are very important to a Java VM author, most notably the com.apple.security.cs.allow-jit -> com.apple.security.cs.allow-unsigned-executable-memory -> com.apple.security.cs.disable-executable-page-protection cascade. My advice on that front: This sequence is a trade off between increasing programmer convenience and decreasing security. com.apple.security.cs.allow-jit is the most secure, but requires extra work in your code. Only set one of these entitlements, because each is a superset of its predecessor. com.apple.security.cs.disable-executable-page-protection is rarely useful. Indeed, on Apple silicon [1] it’s the same as com.apple.security.cs.allow-unsigned-executable-memory. If you want to investigate moving from com.apple.security.cs.allow-unsigned-executable-memory to com.apple.security.cs.allow-jit, lemme know because there are a bunch of additional resources on that topic. What that tells me is that com.apple.security.cs.allow-jit is the recommended entitlement that retains enough security and yet provides the necessary programmer convenience for applications. In the OpenJDK project we use both com.apple.security.cs.allow-unsigned-executable-memory and com.apple.security.cs.allow-jit entitlements for the executables shipped in the JDK (for example java). I was told in that other thread that it might be possible to just use the com.apple.security.cs.allow-unsigned-executable-memory, but there are some additional details to consider. I'm starting this thread to understand what those details are.

I'd like to create a custom SwiftUI view that supports extracting its title string along with the localization comment into a string catalog. Like the SwiftUI Text view does. I have a view with an init similar to the localization init of Text. But it looks like I'm missing something obvious. Two questions: How do I get the actual localized string using a LocalizedStringKey? Why is the comment not picked up and added to the string catalog? // 1) My custom view with localization support: // I'd like to build a view which supports extraction of strings into a string catalog like the SwiftUI `Text` view does. struct MyLocalizableView: View { private var localizedTitle: String init (_ titleKey: LocalizedStringKey, table: String? = nil, bundle: Bundle? = nil, comment: StaticString? = nil) { // PROBLEM I: // The following line does not work. I is a fantasy call. It depicts my idea how I would expect it to work. // My question is: How do I get the actual localized string using a `LocalizedStringKey`? self.localizedTitle = String(localizedKey: titleKey, table: table, bundle: bundle, comment: comment) } var body: some View { // At this point I want to do an operation on an actual string and not on a LocalizedStringKey. So I can't just pass the LocalizedStringKey value along. // Do `isEmpty` or some other operation on an actual string: if localizedTitle.isEmpty { Text("Show one thing") } else { Text("Show another thing") Text("** \(localizedTitle) **") } } } // 2) The call site: struct ContentView: View { var body: some View { // PROBLEM II: "My title key" is picked up and is extracted into the string catalog of the app. But the comment is NOT! MyLocalizableView("My title key", comment: "The title of the view...") .padding() } }

I have a NSViewController as the root view and have a switui view embedded in it via NSHostingView. override func loadView() { self.view = NSHostingView(rootView: SwiftUiView()) } } In the SwiftUiView, I have a TextField and an NSTextView embedded using NSViewRepresentable, along with a few buttons. There is also a menu: Menu { ForEach(menuItems), id: \.self) { item in Button { buttonClicked() } label: { Text(item) } } } label: { Image("DropDown") .contentShape(Rectangle()) .frame(maxWidth: .infinity) .frame(maxHeight: .infinity) } The NSTextView and TextField work fine, and I can type in them until I click on the menu or show an alert. After that, I can no longer place my cursor in the text fields. I am able to select the text but not type in it. When I click on the NSTextView or TextField, nothing happens. At first, I thought it was just a cursor visibility issue and tried typing, but I received an alert sound. I've been trying to fix this for a couple of days and haven't found any related posts. Any help would be greatly appreciated.

Since macOS 15.4 Beta 2, my App Store has been unable to install or download any new applications; it can only download applications I have previously purchased. It appears as follows: when I click 'Get,' the system spins to load and then returns to the initial state. Upon checking system error reports, it seems there's an issue with AMSUIPaymentViewService_macOS [2113]. This problem persists despite changing credit cards or even removing all credit cards. macOS 15.4 Beta 3 has not fixed this error.

I am looking for inputs to better understand MacOS entitlements. I ask this in context of OpenJDK project, which builds and ships the JDK. The build process makes uses of make tool and thus doesn't involving building through the XCode product. The JDK itself is a Java language platform providing applications a set of standard APIs. The implementation of these standard APIs internally involves calling platform specific native library functions. In this discussion, I would like to focus on the networking functions that the implementation uses. Almost all of these networking functions and syscalls that the internal implementation uses are BSD socket related. Imagine calls to socket(), connect(), getsockopt(), setsockopt(), getaddrinfo(), sendto(), listen(), accept() and several such. The JDK that's built through make is then packaged and made available for installation. The packaging itself varies, but for this discussion, I'll focus on the .tar.gz archived packaging. Within this archive there are several executables (for example: java, javac and others) and several libraries. My understanding, based on what I have read of MacOS entitlements is that, the entitlements are set on the executable and any libraries that would be loaded and used by that executable will be evaluated against the entitlements of the executable (please correct me if I misunderstand). Reading through the list of entitlements noted here https://developer.apple.com/documentation/bundleresources/entitlements, the relevant entitlements that an executable (like "java") which internally invokes BSD socket related syscalls and library functions, appear to be: com.apple.security.network.client - https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.security.network.client com.apple.security.network.server - https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.security.network.server com.apple.developer.networking.multicast - https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.developer.networking.multicast Is my understanding correct that these are the relevant ones for MacOS? Are there any more entitlements that are of interest? Would it then mean that the executables (java for example) would have to enroll for these entitlements to be allowed to invoke those functions at runtime? Reading through https://developer.apple.com/documentation/bundleresources/entitlements, I believe that even when an executable is configured with these entitlements, when the application is running if that executable makes use of any operations for which it has an entitlement, the user is still prompted (through a UI notification) whether or not to allow the operation. Did I understand it right? The part that isn't clear from that documentation is, if the executable hasn't been configured with a relevant entitlement, what happens when the executable invokes on such operation. Will the user see a UI notification asking permission to allow the operation (just like if an entitlement was configured)? Or does that operation just fail in some behind the scenes way? Coming back to the networking specific entitlements, I found a couple of places in the MacOS documentation where it is claimed that the com.apple.developer.networking.multicast entitlement is only applicable on iOS. In fact, the entitlement definition page for it https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.developer.networking.multicast says: "Your app must have this entitlement to send or receive IP multicast or broadcast on iOS. It also allows your app to browse and advertise arbitrary Bonjour service types." Yet, that same page, a few lines above, shows "macOS 10.0+". So, is com.apple.developer.networking.multicast entitlement necessary for an executable running on MacOS which deals with multicasting using BSD sockets? As a more general comment about the documentation, I see that the main entitlements page here https://developer.apple.com/documentation/bundleresources/entitlements categorizes some of these entitlements under specific categories, for example, notice how some entitlements are categorized under "App Clips". I think it would be useful if there was a category for "BSD sockets" and under that it would list all relevant entitlements that are applicable, even if it means repeating the entitlement names across different categories. I think that will make it easier to identify the relevant entitlements. Finally, more as a long term question, how does one watch or keep track of these required entitlements for these operations. What I mean is, is it expected that application developers keep visiting the macos documentation, like these pages, to know that a new entitlement is now required in a new macos (update) release? Or are there other ways to keep track of it? For example, if a newer macos requires a new entitlement, then when (an already built) executable is run on that version of macos, perhaps generate a notification or some kind of explicit error which makes it clear what entitlement is missing? I have read through https://developer.apple.com/documentation/bundleresources/diagnosing-issues-with-entitlements but that page focuses on identifying such issues when a executable is being built and doesn't explain the case where an executable has already been shipped with X entitlements and a new Y entitlement is now required to run on a newer version of macos.

Accessing a directory on my custom distributed filesystem results in a kernel panic. According to the backtrace, the last function called before the panic is triggered is mac_label_verify(). See the backtrace file attached. mac_label_verify-panic.txt The panic manifests itself given the following conditions: Machine-a: make a directory in Finder. Machine-b: remove the directory created on machine-a in Finder. Machine-a: access the directory removed on machine-b in Finder. Kernel panic ensues. The panic is reproducible on both Apple Silicon and x86-64. The backtrace is for x86-64 as I wasn't able to symbolicate it on Apple Silicon. Not sure how to tackle this one. Any pointers would be much appreciated.

When a parent view is selected for the detail pane of a NavigationSplitView subviews appear as expected but not with the dimensions set by .frame on the subview. Toggling the flag works as expected, appearing the subview with the idealWidth. I persist the flag in a SwiftData @Model class so that on restart and first appearance of the parent view the Right View subview presence is as it was left. The problem is that the .frame size is ignored, apparently. No manner of programatic view refresh seems to trigger a resize to the preferred values, only toggling the flag. Is there a better way to handle a collapsing subview in an HSplitView? Why is the .frame not respected? In this example I've added the else clause so HSplitView always has two views with .frame settings but the result is the same without it. VStack { HSplitView { VStack { Text("left view") } .frame( minWidth: 100, idealWidth: .infinity, maxWidth: .infinity, maxHeight: .infinity ) if documentSettings.nwIsPieChartShowing { VStack { Text("right view") } .frame( minWidth: 100, idealWidth: 200, maxWidth: .infinity, maxHeight: .infinity ) } else { Text("") .frame( minWidth: 0, idealWidth: 0, maxWidth: 0, maxHeight: .infinity ) } } HStack { Button("Right View", systemImage: { documentSettings.nwIsPieChartShowing ? "chart.pie.fill" : "chart.pie"}(), action: { documentSettings.nwIsPieChartShowing.toggle() } ) } } } } MacOS Sequoia 15.3.1, Xcode 16.2

Hi all, I am looking for a futureproof way of getting the Screen Resolution of my display device using SwiftUI in MacOS. I understand that it can't really be done to the fullest extent, meaning that the closest API we have is the GeometeryProxy and that would only result in the resolution of the parent view, which in the MacOS case would not give us the display's screen resolution. The only viable option I am left with is NSScreen.frame. However, my issue here is that it seems like Apple is moving towards SwiftUI aggressively, and in order to futureproof my application I need to not rely on AppKit methods as much. Hence, my question: Is there a way to get the Screen Resolution of a Display using SwiftUI that Apple itself recommends? If not, then can I rely safely on NSScreen's frame API?

We are building a 'server' application that can either run as a daemon or can run in background without showing any GUI. Basically, the end user can either configure this to run as a daemon so that it can be tied to the user's session or will launch the process which user will start and quit as needed. I wanted to understand what is the recommended mechanism for such an application from Apple - Should this application be built as a macOS Bundle ? Apple documentation also says that we should not daemonize the process by calling fork. Hence if we create a unix-style executable, will I not need to fork to make it run in a detached state when I launch the executable via double-click ? [Reference Link] Is it fine to have an application on macOS which is a bundle but does not show any UI when launched by double click on the app-icon or via 'open'? While we have been able to achieve this by using NSApplicationMain and not showing the UI, was wondering if using CFRunLoop is best for this case as it is a non-gui application. If we can get the right documentation link or recommendations on how we should build such an application which can run in a non-gui mode and also in a daemonized manner, it will help us. Should the application be always built as a macos bundle or should it be a unix-style executable to support both the cases - by the same application/product and how should we look at the distribution of such applications.

Issue - Safari application not fetched from system_profile command Use case - We are trying to get list of installed applications in the mac. For this we use System_profiler command to fetch the details list. It is working good, but the thing is , It doesnt fetch Safari app as an installed Application. Command used - **/usr/sbin/system_profiler SPApplicationsDataType** Can anyone suggest any other way to fetch the installed applications list from the mac , which includes all the apps (including safari app) and remains effective ?

I am trying to install macOS Big Sur on my VM. It gets stuck on “About 14 minutes remaining ”Does anyone know how to get past it?

Is it possible to change the default save dialog that appears when creating a document based MacOS app in SwiftUI? I have a basic FileDocument struct that gets called to a view using a DocumentGroup scene. struct MyFile: FileDocument { static let readableContentTypes: [UTType] = [.myFileType] static let writeableContentTypes: [UTType] = [.myFileType] var list: [String] init(configuration: ReadConfiguration) throws { let data = configuration.file.regularFileContents! let JSONDecoder = JSONDecoder() do { try list = JSONDecoder.decode([String].self, from: data) } catch { throw CocoaError(.fileReadCorruptFile) } } func fileWrapper(configuration: WriteConfiguration) throws -> FileWrapper { let JSONEncoder = JSONEncoder() JSONEncoder.outputFormatting = .prettyPrinted do { data = try JSONEncoder.encode(self.list) } catch { print(error.localizedDescription) throw CocoaError(.fileWriteUnknown) } return .init(regularFileWithContents: data) } } This gets called at the DocumentGroup DocumentGroup(newDocument: MyFile(), editor: { document in ContentView(document: document.$document) }) But when I save the file, I want the save dialog that appears to have something like a 'Tags' textField that can also store information about the file. Something similar to this: (https://i.sstatic.net/AJQ3YNb8.png) From what I can find, there isn't much information about this other than manually creating an NSSavePanel class and overriding the current save function

The application search for the occurences of a string into files and folders. Everything work fine until I enable sanbox. Then opendir(path_to_folder) report "Operation not permitted". By example dp = opendir("/Users/alain/Desktop"); set dp to NULL for my own Desktop. The application need only read access. How can I get this access ?
