When I tried turning on ENABLE_ENHANCED_SECURITY = YES in an Xcode 26.1 beta project, I got a bunch of "module file not found" errors like this: While building module 'CoreServices': In file included from <module-includes>:1: /Applications/Xcode26.1-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/CoreServices.framework/Headers/CoreServices.h:19:2: fatal error: module file '/Volumes/Work/Xcode-derived/PlainCalc3-gixjfymjqamwmufdwcseugzjehqa/Build/Intermediates.noindex/ExplicitPrecompiledModules/CoreFoundation-5POB3HW0BHFSPWLD7DOOKAULM.pcm' not found: module file not found 19 | #include <CoreFoundation/CoreFoundation.h> | ^ I tried deleting the project's derived data. Is this a known issue?

Hi! I am adding MacOS to a SwiftUI based multiplatform app in XCode, and have noticed an effect on the OTF font I am using. When started for a MacOSX target, the font looks a bit fuzzy, or too bold for the same display: Above is the display running in an iPhone 13 mini simulator, below the macOS version running for the "My Mac" target. The font is in both cases just fetched with static let tkDisplayFont = Font.custom("Segment7Standard", size: 38) Same applies in dark mode: This makes the numbers and especially the decimal point a bit harder to read. The same happens with the system font, but it is not such a problem there: I guess this is handled a bit differently between UIFont and NSFont underneath. Is there a way to tell the font to behave the same way as on iOS?

I have some working Objective-C code that displays a WKWebView and allows printing that content. However, it uses the method -[WKWebView printOperationWithPrintInfo:], which the documentation says is deprecated as of macOS 10.15. However, it doesn't say why this method is deprecated, or what the recommended replacement is. The declaration in WKWebView.h does not even indicate that the method is deprecated. But as an alternative, I tried using +[NSPrintOperation printOperationWithView:printInfo]. Doing it that way just prints a blank page. So, should I keep doing it the doubtful way?

Hi Team, We are trying to understand deep sleep behaviour, can you please help us clarifying on the below questions: When will we configure Hibernate 25, is it valid for M series MacBooks? Is Hibernate 25 called deep sleep mode? What are the settings I need to do on Mac, to make my Mac go in to deep sleep? When awakening from deep sleep , what would be macOS system behaviour? If we have custom SFAuthorization plug in at system.login.screensaver, what would be the behaviour with deep sleep?

My code was running with with the version before Xcode 26 RC. I recompiled one last time. Now I'm getting the error: A server with the specified hostname could not be found let now = Calendar.current.date(byAdding: .hour, value: 1, to: Date())! let nextWeek = Calendar.current.date(byAdding: .day, value: 14, to: Date())! do { let (dailyForecast, hourlyForecast, currentWeather, alertWeather) = try await weatherService.weather(for: thisLocation, including: .daily, .hourly(startDate: now, endDate: nextWeek), .current, .alerts) Suggestions?

I work on a MacBook Pro M3 Max 36GB RAM I am running macOS Tahoe Version 26.1 Beta (23B5042k) The last few days I had a couple of situations where Blender 4.5 LTS Froze and I had to forcequit, I noticed Blender would get Deleted with no notification after the forcequit, it was nowhere to be found on the Application List, Finder. Thought it was a blender issue because I run a special module with it. However around 30min ago I was using Mem and the App froze and I had to ForceQuit, The app also got removed, is not on the list of application and nowhere to be found however the icon on the dock which remained shows a Question Mark. I think this is an OS Behavior I just dont know what to attribute it to.

Hi everybody, I use a very old photo software called Snapseed v 1.2.1 on 2 MacBook, one runs with El Capitan and the second runs with Mojave. These app has no language selection during install, and no preferences language choice in menu when running. When I execute app on El Capitan, all menus and topics are translate in French, but on Mojave no translation is done. I looked Contents of app and found differents languages files (structured as xx.po where xx=country) located in Resources folder. I deduced translation was executed after getting language param. I checked values on both systems and there are same (LANG=fr_FR.UTF-8). So I tried to change Info.plist file to force code langage to 'fr' in CFBundleLocalizations key. Result is same. Does somebody has a idea of reason of issue and how to solve it ? Snapseed release was 2012, El Capitan 2015 and Mojave 2018, it seems framework used to code app runs differently and can't get language value.

I have an existing Mac app which has evolved through over twenty years of development. It is currently written in a mixture of C++ and Objective-C, with a bit of C and Swift in a few places. For a few years now, I have been tinkering with replacing the UI with SwiftUI. The model has been completely rewritten in Swift and works fine. After a few tries, no version has been working acceptably, so I'm thinking that I need to rethink the architecture. The UI consists of a window with a master-detail view. The detail view is what users spend most of their time with. It contains a lot of subviews, around 100 typically. Keyboard events affect the display, so I've had a dedicated data structure to hold the state that is needed for displaying all the subviews. Using Instruments, I see that the view seems to recreate the subviews three times per keyboard event, so I'm clearly doing something wrong. A second factor is that there are a couple of dozen commands that are applicable to the detail view, driven either by menu items, keyboard shortcut, or toolbar button. Adding all of those to the view makes for a massive SwiftUI View, which seems unlikely to be good practice. The current implementation has the controller class broken up with categories, but still they are big classes. Most SwiftUI stuff on the web is iOS-oriented, and typically has a focus on fairly simple apps, so the whole topic of dealing with menu commands doesn't get a lot of coverage, so I've been doing all that through my own solutions, which are probably nothing like optimal. What I've been able to find is not particularly helpful for a full-fledged application like mine, so I'm looking for advice on how to structure the app. The existing one is largely MVC, but I've tried a similar approach and a shot at MVVM, but I'm not getting good results so far. So, pointers, places I can read more, or samples of real-world apps is what I'm after. Anyone?

Dear Team, We have developed a macOS app using Unity (6000.0.51f1) that includes learning activities, assessments/tests, audio recording, and video playback functionalities. For security and content protection, we want to restrict the ability for users to capture screenshots or screen recordings of the app (especially via the built-in Cmd+Shift+5 / Screenshot toolbar). We have attempted several approaches, but they have not been reliable. We would appreciate guidance from Apple or the developer community on the feasibility of this requirement. Our requirements: Block or disable screenshots/screen recordings (particularly the built-in Cmd+Shift+5) for the app. Preferably achieve this using public APIs so that the app remains App Store compatible and passes review. If full blocking is not possible, then at least ensure that any captured content appears blank/black for sensitive sections of the app. Additionally, we would like our app’s window behavior to work like other apps do: Red button → Close the application completely. Yellow button → Minimize the application to the Dock. Green button → Maximize to full screen while still allowing access to the Dock and menu bar. Any advice, best practices, or references to relevant documentation would be highly valuable. Thank you for your support.

I encountered an undesired DNS behaviour when using L2TP/ipsec VPN. I have DHCP configured Wi-Fi connection, which send dns servers and search domain (192.168.0.10, lan) VPN sends its own DNS server (10.0.0.2), search domain (intranet) is added manually in VPN DNS config settings. I expect, when VPN is connected, to be still able to resolve local names, i.e some-host.lan. However, they become unresolvable. quick check shows that the remote dns server is used to resolve local names. shilishper@mac ~ % host -v some-host.lan Trying "some-host.lan" Host some-host.lan not found: 3(NXDOMAIN) Received 106 bytes from 10.0.0.2#53 in 16 ms Received 106 bytes from 10.0.0.2#53 in 16 ms Actually, all dns queries are going to the remote server. I would expect that only queries for the configured domain (intranet) should go to that server. I played with the service order, but it didn't change anything. Is anything can be done about this, programmatically? PS new to macOS, but have extensive linux knowledge

Hi All, I work on a cross platform app, iOS/macOS. All devises on iOS could synchronize data from Coredata : I create a client, I see him an all iOS devices. But when I test on macOs (with TestFlight) the Mac app could not get any information from iOs devices. On Mac, cloud drive is working because I could download and upload documents and share it between all devices, so the account is working but with my App on MacOS, there is no synchronisation. idea????

Hi, I am looking for guidance on how to create a scrollable song list, such as the attachment. The song list was originally created in C#, using an RTF object and populated by about 43 lines of song criteria. What similar approach would I use in Swift and MacOS? By the way, I currently play music that resides on the Mac, no external streaming is required or desired. Thanks, Jim

There appears to be some unexplained change in behaviour in the recent version of macos 15.6.1 which is causing the BSD socket sendto() syscall to no longer send the data when the source socket is bound to a IPv4-mapped IPv6 address. I have attached a trivial native code which reproduces the issue. What this reproducer does is explained as a comment on that code's main() function: // Creates a AF_INET6 datagram socket, marks it as dual socket (i.e. IPV6_V6ONLY = 0), // then binds the socket to a IPv4-mapped IPv6 address (chosen on the host where this test runs). // // The test then uses sendto() to send some bytes. For the sake of this test, it uses the same IPv4-mapped // IPv6 address as the destination address to sendto(). The test then waits for (a maximum of) 15 seconds to // receive that sent message by calling recvfrom(). // // The test passes on macos (x64 and aarch64) hosts of versions 12.x, 13.x, 14.x and 15.x upto 15.5. // Only on macos 15.6.1 and the recent macos 26, the test fails. Specifically, the first message that is // sent using sendto() is never sent (and thus the recvfrom()) times out. sendto() however returns 0, // incorrectly indicating a successful send. Interesting, if you repeat sendto() a second message from the // same bound socket to the exact same destination address, the send message is indeed correctly sent and // received immediately by the recvfrom(). It's only the first message which goes missing (the test uses // unique content in each message to be sure which exact message was received and it has been observed that // only the second message is received and the first one lost). // // Logs collected using "sudo log collect --last 2m" (after the test program returns) shows the following log // message, which seem relevant: // ... // default kernel cfil_hash_entry_log:6088 <CFIL: Error: sosend_reinject() failed>: // [86868 a.out] <UDP(17) out so 59faaa5dbbcef55d 127846646561221313 127846646561221313 age 0> // lport 65051 fport 65051 laddr 192.168.1.2 faddr 192.168.1.2 hash 201AAC1 // default kernel cfil_service_inject_queue:4472 CFIL: sosend() failed 22 // ... // As noted, this test passes without issues on various macosx version (12 through 15.5), both x64 and aarch64 but always fails against 15.6.1. I have been told that it also fails on the recently released macos 26 but I don't have access to such host to verify it myself. The release notes don't usually contain this level of detail, so it's hard to tell if something changed intentionally or if this is a bug. Should I report this through the feedback assistant? Attached is the source of the reproducer, run it as: clang dgramsend.c ./a.out On macos 15.6.1, you will see that it will fail to send (and thus receive) the message on first attempt but the second one passes: ... created and bound a datagram dual socket to ::ffff:192.168.1.2:65055 ::ffff:192.168.1.2:65055 sendto() ::ffff:192.168.1.2:65055 ---- Attempt 1 ---- sending greeting "hello 1" sendto() succeeded, sent 8 bytes calling recvfrom() receive timed out --------------------- ---- Attempt 2 ---- sending greeting "hello 2" sendto() succeeded, sent 8 bytes calling recvfrom() received 8 bytes: "hello 2" --------------------- TEST FAILED ... The output "log collect --last 2m" contains a related error (and this log message consistently shows up every time you run that reproducer): ... default kernel cfil_hash_entry_log:6088 <CFIL: Error: sosend_reinject() failed>: [86248 a.out] <UDP(17) out so 59faaa5dbbcef55d 127846646561221313 127846646561221313 age 0> lport 65055 fport 65055 laddr 192.168.1.2 faddr 192.168.1.2 hash 201AAC1 default kernel cfil_service_inject_queue:4472 CFIL: sosend() failed 22 ... I don't know what it means though. dgramsend.c

Hallo all, I did a test integration of MetricKit into one of our apps...I'am on macOS Ventura 13.3.1 (a). The app is not distributed via the App Store. I subscribed to the MXMetricManager and implemented the didReceiveDiagnosticPayloads function. So far everything seems to work, when I use in Xcode: Debug -> Simulate MetricKit Payload I get a callback and the payload. So I did some further testing. When I build the app debug version with a test crash and then run the Debug Version (without Xcode) and let it crash the next time I start the app I get a callback to didReceiveDiagnosticPayloads with all the information about the crash. But I'am not able to get a hang report. I tested it by adding a sleep (60) and adding some intensive computation work on the main thread so that it is busy for several seconds, I get no hang reports :-( I'am using the Debug version and run it without Xcode. Are hang reports expected to be reported immediately? I also get after 24 hours no hang reports. Can someone help me? Thanks and have a nice day!

Hi, I’m expecting the demo from Apple, but I think I’m seeing different behavior on my end. Here are the steps I followed: Run the SampleEndpointApp example. Copy SampleEndpointApp to the /Applications folder. Run and enable the Extension and Full Disk Access → Everything works properly. I modify something in the example and start again from step #1, but nothing gets updated as shown in the demo video. The only way I can make it work is by going into Settings, manually removing the ES extension, and then running the app again. My concern is: if I deliver the application to clients, how can I properly update the extension without requiring them to manually remove it first? Thanks,

Hi, A user logs in to the file vault, and DisableFDEAutoLogin is false. The file vault login succeeds, but the login to the selected user fails. The user gets the login screen again. If the user puts an invalid password to try and login again, the loginwindow:FDESupport plugin will change the user's password to the invalid one.

We are in the process of updating our legacy Spotlight MDImporter to the new macOS Spotlight App Extension. The transition works well for standard attributes such as title, textContent, and keywords. However, we encounter an issue when adding custom attributes to the CSSearchableItemAttributeSet. These custom attributes are not being persisted, which means they cannot be queried using a Spotlight NSMetadataQuery. Has anyone an idea on how to append custom attributes so that they are included in the indexed file status, as displayed by the shell command mdimport -t -d3 <path> A sample project illustrating the problem is available here: https://www.dropbox.com/scl/fi/t8qg51cr1rpwouxdl900b/2024-09-04-Spotlight-extAttr.zip?rlkey=lg6n9060snw7mrz6jsxfdlnfa&dl=1

Hello all, I saw the update of xcode26 on the App store, and from the compatibility information, I saw that xcode26 supports macos15.6 and higher. I'm not sure if xcode26 can be installed on macos 15. I can't install xcode26 on macOS 15.7.
