I see that in the link https://developer.apple.com/documentation/virtualization/vzvirtualmachineconfiguration/graphicsdevices?changes=late_7_8 graphicsDevices accepts and array. So it is possible to have multiple displays for a virtual machine. But when i tried it with multiple displays it does not work. Why do we have it as an array if it does not support multiple displays.? or how to get it work with multiple displays.

Hello, According to the official documentation, the macOS Virtualization Framework currently supports only macOS and Linux guest operating systems. I would like to know if there is any way—officially or through a supported workaround—to run Windows 11 as a guest using this framework. Additionally, is there any indication or roadmap suggesting that support for Windows guests might be introduced in a future release, such as in macOS 16? Any insights or official clarification would be greatly appreciated. Thank you.

HI, I am using mac os virtuzlation framework for running virtual machines. At prenset i add the shared folders when creating the VzVirtualMachine. Is it possible to add shared folders to running VZVirtualMachine Thannks

HI, I have a Swift UI app in the mac appstore in the upcoming release we have made lots of changes and it is working fine in debug mode but in production with testflight or direct distribution we are getting the following crash while working in the app. this is happening in the rendering phase.

I have this code in my Virutalization application let process = Process() process.executableURL = URL(fileURLWithPath: "/usr/sbin/diskutil") process.arguments = ["image", "create", "blank", "--fs", "none", "--format", "ASIF", "--size", "2GiB", url.path ] try process.run() process.waitUntilExit() if process.terminationStatus == 0 { print("✅ Disk image creation succeeded.") } else { print("❌ Disk image creation failed with exit code \(process.terminationStatus)") } } catch { print("Process failed to launch: \(error.localizedDescription)") return } this code was working fine until Tahoe 26.2. with the update of 26.3 the system freezes at process.waitUntilExit() The code never exits and i get beech balls. This is working fine with intel macs. i am getting the problem in apple silicon m4 mac mini. Any help would be appreciated.

I see this in Tahoe Beta release notes macOS now supports the Apple Sparse Image Format (ASIF). These space-efficient images can be created with the diskutil image command-line tool or the Disk Utility application and are suitable for various uses, including as a backing store for virtual machines storage via the Virtualization framework. See VZDiskImageStorageDeviceAttachment. (152040832) I'm developing a macOS app using the Virtualization framework and need to create disk images in the ASIF (Apple Sparse Image Format) to make use of the new feature in Tahoe Is there an official way to create/resize ASIF images programmatically using Swift? I couldn’t find any public API that supports this directly. Any guidance or recommendations would be appreciated. Thanks!

Hi all, I'm trying to add Spotlight support to a macOS app that handles custom virtual machine bundles with the .vpvm extension. I’ve followed the current documentation and used the modern CSImportExtension approach with a Spotlight Importer extension target. Here’s what I’ve done: App Info.plist: Declared com.makeprog.vpvm as a UTI conforming to com.apple.package. Registered it under UTExportedTypeDeclarations and CFBundleDocumentTypes. Spotlight Importer Extension: Added a new macOS target using the Spotlight Import Extension template. Set the NSExtensionPointIdentifier to com.apple.spotlight.import. Used CSSupportedContentTypes = com.makeprog.vpvm. Implemented a minimal update(_ attributes:forFileAt:) method that sets displayName, title, and contentDescription. Other steps: Verified that the .appex is embedded under Contents/PlugIns/. Confirmed it appears in mdimport -e output with correct UTI. Used mdimport -m -d2 -t /path/to/file.vpvm, but I still get: Imported '/path/to/file.vpvm' of type 'com.makeprog.vpvm' with no plugIn. The extension is never invoked. I’ve also tried: Ensuring the .vpvm file is a valid directory bundle. Restarting Spotlight / rebuilding index. Ensuring the app and extension are properly signed. Tried installing the app in test virtual machine Question: Has anyone successfully used CSImportExtension for custom UTIs? Is there something additional I need to do for the extension to be recognized and triggered? Any advice or examples would be greatly appreciated! Thanks in advance.

Hi, I would like to reset system window private picker alert with ScreenCapture kit. i can reset the ScreenCapture permission with tccutil reset ScreenCapture. but it does not reset the system window private picker alert. i tried deleting the application directory from container and it does not help. the system window private picker alert uses the old approval i gave and it does not prompt a new alert. How can i starta with fresh screencapture kit settings for an app in testing? Thanks

Hi, I'm using ScreenCaptureKit on macOS 14+ to record a single window. I've noticed that the Presenter Overlay only appears when capturing the entire screen, but it does not appear when recording a specific window or a region. Is there a way to enable the Presenter Overlay while recording a single window or a defined region, similar to how it works with full-screen capture? Any guidance or clarification would be greatly appreciated. Thanks in advance!

Hello, I'm developing a macOS application that uses the Virtualization framework to run Linux virtual machines (specifically Ubuntu and Fedora) on Apple Silicon Macs. I've noticed that while the macOS host properly supports all trackpad gestures, the two-finger tap gesture for right-click does not work within the Linux guest. Only the primary click is recognized. This behavior is consistent across different Linux distributions and desktop environments (GNOME, KDE, etc.). I would like to confirm: Is the macOS Virtualization framework expected to support trackpad gestures such as two-finger tap for right-click within Linux guest VMs? If not currently supported, is there a known workaround to enable right-click functionality for the trackpad in Linux guests? (e.g., configuration changes in the VM, Linux kernel input modules, or framework-level adjustments.) Any insights or suggestions would be greatly appreciated. Thank you!

I am using macOS virtualization farmework and able to create nad and run VMS. I need to resize the disk images using hdiutil in app sandbox environment. Is that possible? i tried disabling sandbox and it worked ok. But with sandbox i get the error message device is not configured. If this cant be done in sandbox what could be the alternative way to to achive this in sandboxed app. thanks

Hi, In mac os swift ui application when i set window.isReleasedWhenClosed and when i close the window the app is getting crashed with exc_bad_access. but when i leave it to default value the app is not crashing. for some windows setting window.isReleasedWhenClosed to true is woking properly when closing the windows. But for some windows it is crashing. If i dont set it to true the window is not removed from NSApplication.shared.windows sometimes. I am confused about setting isReleasedWhenClosed to true Could someone calrify on this please. thank in advance.

I have developed an app to create and run virual machines using mac os virtualization framework for apple siicon and intel macs. I have tried ubuntu, fedora, debian & linux mint distros and they all worked fine with intel macs. But when i try to run other distros like mx linux, manjaro, pop os, endevour os etc on intel mac they all on booting iso just shows the black screen. is there any list of officilay support linux distros for intel macs and apple silicon. the support of linux distros are fairly limited or am i missing something.
