Logic Pro recently changed the way it accepts drag and drop. If the ItemProvider contains UTType.midi, then Logic Pro shows visual feedback for the drop operation, but when the item is dropped, nothing happens. In the past, drag-and-drop used to work. With today's version (Logic Pro 11.2), the only way I was able to successfully drop MIDI was to provide UTType.fileURL and no other data types. But that's not a viable solution; I need other data types to be included too. As a side note, I tested with Ableton Live 12 and it works with no issue. Is this a bug in Logic Pro? What ItemProvider structure does Logic Pro expect to correctly receive the MIDI data?

I am an audio plugin developer. 11.2.1 we were able to drag audio from the arrange page into the plugin. 11.2.2. that is now broken. I saw someone have a similar post, but MIDI. Any help would be greatly appreciated.

I submitted my last macOS application with IAP on Oct. 23rd, 2025. I was able to test-purchase a non-consumable product with the StoreKit configuration file at that time. These days, every time I test a new macOS application with the configuration file, a purchase process fails. The thing is they all now fail if I test the store with existing applications that were once working. Xcode shows the following debugging error. Purchase failed with error: systemError(Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service created from an endpoint was invalidated from this process." UserInfo={AMSDescription=An unknown error occurred. Please try again., AMSURL=http://localhost:53272/WebObjects/MZBuy.woa/wa/inAppBuy, NSDebugDescription=The connection to service created from an endpoint was invalidated from this process., AMSStatusCode=200, AMSServerPayload={ All my iOS apps don't exhibit the same problem. This StoreKit fiasco only happens for macOS applications. And I'm thinking that it all started to occur after I began using Xcode 26. Not a single line of code has changed. But the applications that were once able to process IAP all now fail. And I'm suspecting that it's Xcode 26 that is responsible for this failure. My Xcode version is 26.2, by the way. Any macOS application developer experiencing the same problem?

I am currently developing an app for MacOS that needs to control HomeKit devices like lights. However, it seems like MacOS is supported on the official documentation, but not when I try to create an app ID on developer.apple.com. On the link https://developer.apple.com/apple-home/, MacOS is clearly showed as supported for MacOS. But when I try to create an app ID, it shows that it is only compatible for iOS, VisionOS and WatchOS. Could this be clarified? Best regards, orangeidle25

Hello, we are currently integrating Writing Tools into our macOS application using NSWritingToolsCoordinator with a custom NSView. Overall, the integration is going well and we are generally satisfied with the API. However, text replacement is sometimes not using NSWritingToolsCoordinator callback function. When selecting “Replace” from a preview in a Writing Tools UI popup, the text replacement is performed via the NSTextInputClient callback function (insertText:), which does not seem correct. This is especially problematic in multi-context scenarios, because NSTextInputClient insertText: does not provide the required information about the Writing tools context being used. As a result, it is not possible to determine which context is being modified when managing more than a single context. In our view, Writing Tools should consistently use the callback function of NSWritingToolsCoordinator for text replacement, whatever is the action performed. This is essential for properly handling multi-context use cases. This issue is reproducible with the sample app project provided here https://developer.apple.com/documentation/appkit/enhancing-your-custom-text-engine-with-writing-tools. If you define a breakpoint in function writingToolsCoordinator:replaceRange:inContext:proposedText:reason:animationParameters:completion: of the Writing tools coordinator, the function is not triggered if text replacement is performed from a preview like for "Summary" with "replace" button. NSWritingToolsCoordinator callback function seems to be called only when text replacement is performed directly inline (in the text view) without external preview so. i have opened a issue with feedback assistant: FB22401950. Best regards.

I have been using this block of Swift code for weeks with no problems. Then, today, every time I invoke it it fails: let openPanel = NSOpenPanel() openPanel.canChooseFiles = true openPanel.allowsMultipleSelection = false openPanel.canChooseDirectories = true openPanel.canCreateDirectories = false openPanel.title = NSLocalizedString("Open a CSV file", comment: "Open a CSV File") var result = NSApplication.ModalResponse.OK do { try result = openPanel.runModal() } catch { print("Open Panel failed: \(error)") return } if result == .OK { CSVFile = openPanel.url!.path } else { openPanel.close() print("No CSV file selected.") return } I get this message pointing to the .openModal expression: "Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value" It's a real head-scratcher!

This is not exactly a feedback about the forums but I couldn't find a better location to ask this question. The macos release notes are hosted at developer.apple.com. For example, the macos 26.4 release note is here https://developer.apple.com/documentation/macos-release-notes/macos-26_4-release-notes. Would it be possible to include the release date in those release notes? Right now, it's hard to locate that information. It would also be useful to even include the sw_vers of that particular release in those release notes. For example: ProductName: macOS ProductVersion: 26.4 BuildVersion: 25E246 Having the sw_vers and the release date in the first few lines of the release note would be handy. The reason I went looking for the release date was because the corresponding sources for macos 26.4 hasn't yet been listed at https://opensource.apple.com/releases/. It usually takes a few days for that to happen, so I wanted to see how long it has been since 26.4 was released.

Mac Pro 2019, Tahoe 26.3, Xcode 26.2 Mac Mini 2023 M2, Tahoe 26.3, Xcode 26.2 On Mac Pro 2019 the app is only Intel while on Mac Mini 2023 M2 it is ARM64 only. Both have Standard Architectures (Apple Silicon, Intel). Both have Build Active Architecture Only is set to No (Debug + Release). Happen for default new projet macOS -> App and Obj-C, Xib. No change to defaults setting except uncheck "Automaticaly manage signing" and "Signing Certificate" set to "Sign to Run Locally" HOWEVER On Mac Pro 2019, BigSur 11.7.10, Xcode 14.10 the application is build Universal ! Why cannot build universal with Tahoe 26.3, Xcode 26.2 ? Can I submit a Mac applcation to App Store Connect with BigSur 11.7.10, Xcode 14.10 ? What are the minimal version of Mac Os and Xcode to submit a Mac applcation to App Store Connect ?

We're developing a Mac App Store application that embeds the V8 JavaScript engine (via Electron). The application has shipped successfully on macOS 15.x with the following entitlements: com.apple.security.app-sandbox = true com.apple.security.cs.allow-jit = true com.apple.security.cs.allow-unsigned-executable-memory = true com.apple.security.cs.disable-library-validation = true On macOS 26 Tahoe, the exact same signed binary crashes deterministically within ~1.5 seconds on Apple Silicon with EXC_BREAKPOINT (SIGTRAP), ESR 0xf2000000. The crash is in V8's background JIT compilation thread when it attempts to manage memory page protections (transitioning pages between Read-Write and Read-Execute states via mprotect). The crash does not occur in these configurations: macOS 26 + App Sandbox + Intel x86_64 — works macOS 26 + Hardened Runtime (no sandbox) + ARM64 — works macOS 15.x + App Sandbox + ARM64 — works This appears to be a regression in how the XNU kernel handles mprotect calls for sandboxed processes on ARM64 under macOS 26, specifically in the context of the allow-jit entitlement. Has the behavior of allow-jit changed in macOS 26 with respect to runtime code generation memory management on ARM64? Is there a new API or entitlement that V8-style JIT engines should use instead of mprotect-based RW↔RX page transitions?

Device Details: MBP M2 Pro AND MBP M3 Pro macOS 26.3 (25D125) Xcode Version 26.3, 26.2, 26.1 (I reinstalled all 3 of these after the macOS update) BUG: Xcode hangs indefinitely when performing Source Control operations (Pull or Push) on a Git repository that uses SSH authentication. The same repository works correctly when performing the equivalent Git operations from the Terminal using the Git CLI. The issue appears to be specific to Xcode’s internal Source Control integration. When the operation is triggered from Xcode, the UI shows a spinning progress indicator and never completes. Terminal Git commands (git fetch, git pull, git push) complete normally using the same SSH key and repository. A hang sample taken during the issue shows the Xcode main thread blocked in Source Control authentication and fingerprint handling code paths, including: IDESourceControlUIHandler IDESourceControlFingerprintManager handleAuthenticationFailure showFingerprintAlertOnWindow This suggests Xcode may be waiting on a Source Control authentication or host fingerprint UI flow that never resolves. SSH connectivity itself is functioning correctly: ssh -T git@bitbucket.org and ssh -T git@github.com both authenticate successfully. git ls-remote, git fetch, git pull, and git push all work correctly from Terminal. No Source Control accounts are configured in Xcode Preferences. Authentication relies entirely on SSH keys. Steps to Reproduce Configure an SSH key for Git access (e.g., Bitbucket or GitHub) and confirm it works via Terminal. Clone or open an existing Git repository that uses SSH (git@host:repo.git). Open the project/workspace in Xcode. In Xcode, attempt a Source Control operation such as: Source Control → Pull Source Control → Push Observe that Xcode displays a spinning progress indicator and does not complete the operation.

I've looked around quite a bit at the EventKit documentation and done all the searching I could think of, as well as examining the EKCalendar and EKEventStore types. Trying to find out how to view, modify, and create groups of reminders lists.

I recently turned on the enhanced security options for my macOS app in Xcode 26.0.1 by adding the Enhanced Security capability in the Signing and Capabilities tab. Then, Xcode adds the following key-value sets (with some other key-values) to my app's entitlements file. <key>com.apple.security.hardened-process.enhanced-security-version</key> <integer>1</integer> <key>com.apple.security.hardened-process.platform-restrictions</key> <integer>2</integer> These values appear following the documentation about the enhanced security feature (Enabling enhanced security for your app) and the app works without any issues. However, when I submitted a new version to the Mac App Store, my submission was rejected, and I received the following message from the App Review team via the App Store Connect. Guideline 2.4.5(i) - Performance Your app incorrectly implements sandboxing, or it contains one or more entitlements with invalid values. Please review the included entitlements and sandboxing documentation and resolve this issue before resubmitting a new binary. Entitlement "com.apple.security.hardened-process.enhanced-security-version" value must be boolean and true. Entitlement "com.apple.security.hardened-process.platform-restrictions" value must be boolean and true. When I changed those values directly in the entitlements file based on this message, the app appears to still work. However, these settings are against the description in the documentation I mentioned above and against the settings Xcode inserted after changing the GUI setting view. So, my question is, which settings are actually correct to enable the Enhanced Security and the Additional Runtime Platform Restrictions?

I lived with knowledge that one needs to provide his login password to unlock the login keychain. This does not seem to be entirely true after upgrading Tahoe to 26.4. For example, on 26.3: Go to ~/Library/Keychains Copy login.keychain-db to different name, say test.keychain-db. Double-click on test.keychain-db -> this should open Keychain Access with test in Custom keychains section, it will appear locked. Select test keychain and press Cmd+L to unlock it. When prompted, provide your login password. Result: the keychain is unlocked. When I preform above sequence of steps on 26.4 I am not able to unlock the copied keychain (the original login keychain appears implicitly unlocked).

Hi, I’m building a macOS tool that analyzes process behavior to detect autonomous / AI-like activity locally (process trees, file access patterns, and network usage). The system is fully user-space and runs locally in real time. I’m planning to use the Endpoint Security Framework for process and file event monitoring. This is an open-source project (non-enterprise), developed by a solo developer. My question: What are the realistic chances of getting Endpoint Security entitlements approved for this type of project? Are there specific requirements or common reasons for rejection I should be aware of? Thanks, sivan-rnd

I have an orphaned asset folder taking up 9.13GB located at: /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime/c0d3fd05106683ba0b3680d4d1afec65f098d700.asset It contains SimulatorRuntimeAsset version 18.5 (Build 22F77). Active Version: My current Xcode setup is using version 26.2 (Build 23C54). I checked the plist files in the directory and found what seems to be the cause of the issue: The "Never Collected" Flag: The Info.plist inside the orphaned asset folder explicitly sets the garbage collection behavior to "NeverCollected": <key>__AssetDefaultGarbageCollectionBehavior</key> <string>NeverCollected</string> The Catalog Mismatch: The master catalog file (com_apple_MobileAsset_iOSSimulatorRuntime.xml) in the parent directory only lists the new version (26.2). Because the old version (18.5) is missing from this XML, Xcode and mobileassetd seem to have lost track of it entirely. What I Have Tried (All Failed) Xcode Components: The version 18.5 does not appear in Settings -> Components, so I cannot delete it via the GUI. Simctl: xcrun simctl list runtimes does not list this version. Running xcrun simctl runtime delete 22F77 fails with: "No runtime disk images or bundles found matching '22F77'." Manual Deletion: sudo rm -rf [path] fails with "Operation not permitted", presumably because /System/Library/AssetsV2 is SIP-protected. Third-party Tools: Apps like DevCleaner do not detect this runtime (likely because they only scan ~/Library or /Library, not /System/Library). Has anyone found a way to force the system (perhaps via mobileassetd or a specific xcrun flag) to re-evaluate this folder and respect a deletion request? I am trying to avoid booting into Recovery Mode just to delete a cache file. Any insights on how AssetsV2 handles these "orphaned" files would be appreciated.

Hello together, I'm currently trying to implement a simple way to use the new LOM commands for our new mac infrastructure. My MDM sollution is a custom instance of MicroMDM. MDM profiles are working fine, but when I send a https://developer.apple.com/documentation/devicemanagement/lom_device_request_command with any command (Reset, PowerON, PowerOFF), then it doesn't reset/restart/start the target Mac. Host X has a device profile and host Y a controller profile. Host/Mac Y = fe80::YYYY:YYYY:YYYY:8608 Host/Mac X = fe80::XX:XXXX:XXXX:cfab Now, if I send a LOM request for Mac Y to reset Mac X, I get the error "Address already in use" on Mac X (logs via log stream) log stream (private logs) And wireshark on Mac X shows there is traffic, but MacX does not respond to anything, not even tcp syn packages. This error is really weird, because there are no special ports running on that mac and I don't know what Port lightsoutmanagementd tries to listen to. lsof | grep LISTEN | grep -i ipv6 launchd 1 root 7u IPv6 0x457f571ac3303fd7 0t0 TCP *:ssh (LISTEN) launchd 1 root 11u IPv6 0x457f571ac33015d7 0t0 TCP *:rfb (LISTEN) launchd 1 root 27u IPv6 0x457f571ac3303fd7 0t0 TCP *:ssh (LISTEN) lightsout 112 root 4u IPv6 0x457f571ac3302ad7 0t0 TCP *:55555 (LISTEN) kdc 143 root 5u IPv6 0x457f571ac33023d7 0t0 TCP *:kerberos (LISTEN) screensha 403 root fp.u IPv6 0x457f571ac33015d7 0t0 TCP *:rfb (LISTEN) (fileport=0x2103) screensha 403 root 3u IPv6 0x457f571ac33015d7 0t0 TCP *:rfb (LISTEN) ARDAgent 535 devops 9u IPv6 0x457f571ac33031d7 0t0 TCP *:net-assistant (LISTEN) Did anyone have the same problem, or maybe can hint me in the right direction? I currently don't have a clue, what I can do next.

I'm writing a read-only filesystem extension. I see that the documentation for loadResource(resource:options:replyHandler:) claims that the --rdonly option is supported, which suggests that this should be possible. However, I have never seen this option provided to my filesystem extension, even if I return usableButLimited as a probe result (where it doesn't mount at all - FB19241327) or pass the -r or -o rdonly options to the mount(8) command. Instead I see those options on the volume's activate call. But other than saving that "readonly" state (which, in my case, is always the case) and then throwing on all write-related calls I'm not sure how to actually mark the filesystem as "read-only." Without such an indicator, the user is still offered the option to do things like trash items in Finder (although of course those operations do not succeed since I throw an EROFS error in the relevant calls). It also seems like the FSKit extensions that come with the system handle read-only strangely as well. For example, for a FAT32 filesystem, if I mount it like mount -r -F -t msdos /dev/disk15s1 /tmp/mnt Then it acts... weirdly. For example, Finder doesn't know that the volume is read-only, and lets me do some operations like making new folders, although they never actually get written to disk. Writing may or may not lead to errors and/or the change just disappearing immediately (or later), which is pretty much what I'm seeing in my own filesystem extension. If I remove the -F option (thus using the kernel extension version of msdos), this doesn't happen. Are read-only filesystems currently supported by FSKit? The fact that extensions like Apple's own msdos also seem to act weirdly makes me think this is just a current FSKit limitation, although maybe I'm missing something. It's not necessarily a hard blocker given that I can prevent writes from happening in my FSKit module code (or, in my case, just not implement such features at all), but it does make for a strange experience. (I reported this as FB21068845, although I'm mostly asking here because I'm not 100% sure this is not just me missing something.)

On Mac Catalyst 26, a Button bar item in a bottom toolbar look squished. This happens only when the "Mac Catalyst Interface" option is set to "Optimize for Mac". When it is set to "Scale to match iPad", the buttons look fine. For example, in the screenshots below, the text button should say "Press Me", instead of "…" A simple reproducible snippet and a screenshot below. The toolbar button comparison between "Scale to match iPad" and "Optimize for Mac" are shown. Optimize for Mac Scale to match iPad import SwiftUI struct ContentView: View { @State private var selectedItem: String? = "Item 1" let items = ["Item 1", "Item 2"] var body: some View { NavigationSplitView { List(items, id: \.self, selection: $selectedItem) { item in Text(item) } .navigationTitle("Items") } detail: { if let selectedItem = selectedItem { Text("Detail view for \(selectedItem)") .toolbar { ToolbarItemGroup(placement: .bottomBar) { Text("Hello world") Spacer() Button("Press Me") { } Spacer() Button { } label: { Image(systemName: "plus") .imageScale(.large) } } } } else { Text("Select an item") } } } }
