v4.1.6

[osy]

This is the same release as v4.1.5 but with the change to default enable GPU acceleration for Linux reverted. This is due to a number of guest-side driver issues in the latest version of Mesa (#4983). As a result of these issues, we decided to disable GPU acceleration in Linux by default for new VMs created by the wizard. If you have an existing VM with graphical issues, you can disable GPU acceleration by going into the VM settings, under Display, change the Emulated Display Card to virtio-gpu-pci or another card that does not have -gl in the name. You can verify that GPU acceleration is disabled when the checkbox below the card is unchecked.

Highlights

• QEMU backend updated to v7.2.0. Also updated usbredir (0.13.0), virglrenderer (latest commit), ANGLE (latest commit)
• Improved renderer backend. Lots of bug fixes and stability improvements to GPU accelerated Linux VMs (most common crashes when GPU acceleration is enabled should be gone now). New option to change the renderer backend to ANGLE Metal and limit FPS (in Preferences). Switching to Metal is highly recommended.
• (iOS) TrollStore build (UTM.HV.ipa) now supports JIT. Additionally, there is now in-app settings.
• (iOS) TrollStore build now supports TSO (Total Store Ordering). TSO is used by Rosetta on the Mac to improve x86_64 emulation on ARM64. It can now be used on M1 iPads with QEMU to improve performance of FEX-Emu or a patched Rosetta. Note that it is recommended that TSO be disabled if you do not need to emulate x86_64 because it can reduce performance of other tasks.
• (macOS) AppleScript (OSA) support and CLI interface. You can control parts of UTM through the OSA interface. Currently there is support for listing VMs as well as start/stop/suspend operations and the ability to print out the guest serial port connections. More functionality will be added in the future. A command line application is also provided in UTM.app/Contents/MacOS/utmctl (which you can symlink to /usr/local/bin/utmctl if desired) that can be used for automation tasks without needing to learn AppleScript.
• (macOS 13+) Menu bar extra. You can enable the menu bar extra icon in Preferences (Cmd+,) as well as disable the dock icon. The menu bar extra provides a minimal interface to start/stop/suspend VMs and is useful when paired with headless VMs (a VM that does not have any display or terminal console installed).

Notes

• iOS 14 and macOS 11.3 are the minimum supported systems for UTM v4.x. Please use UTM v3.x for support down to iOS 11 and macOS 11
• Newly created Linux VMs will now use virtio-gpu-gl-pci by default. It is recommended that you change the display card of existing QEMU backend Linux VMs to this card in order to take advantage of the improved renderer backend. This should result in improved performance in GUI rendering. Note that some applications (particularly 3D applications) may lock up or crash UTM and if you are experiencing issues, you can go back to virtio-ramfb or virtio-vga.
• Newly created Windows VMs will now use virtio-ramfb-gl (Apple Silicon) or virtio-vga-gl (Intel) by default. There is NO 3D acceleration drivers for Windows yet, so unlike Linux, this will not improve any compatibility with applications. However, the GL backend can still be beneficial to Windows users because it has smoother animations and less tearing and artifacts. The overall benefits will not be as pronounced as for Linux VMs so it is optional that you change existing VMs to a -gl display card.
• (iOS) It is recommended that you switch to the Metal backend in Preferences for better performance. However, some applications such as glxgears will not work with the Metal backend.

Changes (v4.1.6)

• Wizard: Re-introduced the checkbox for "Hardware OpenGL Acceleration" which is disabled by default due to guest-side issues in the latest Mesa driver

Changes (v4.1.5)

• Improved rendering of non-GL graphics on the new renderer backend. This should reduce some of the tearing seen in earlier updates. For the best performance, it is recommended that a GL backend is selected.
• Support read-only disk images in QEMU backend as well as selecting images that are read-only (Can't mount read-only ISOs #4838) Note: all external drive images (ISOs) are now loaded as read-only, this was not enforced in previous versions due to an error in the logic.
• Newly created Windows VMs will now use virtio-ramfb-gl (Apple Silicon) or virtio-vga-gl (Intel) by default. See the Notes section for more information.
• Fixed an issue where the incorrect tmp directory path was used by QEMU (QEMU exited from an error: Operation not permitted #4882)
• Scripting: Fixed an issue where the proper error message was not displayed in some cases.
• CLI: Improved some help text.
• Localization: updated Japanese (thanks @MMP0)

Changes (v4.1.4)

• Fixed slow rendering of GRUB and EFI menus
• Introduced new optimizations to renderer: bliting done on GPU instead of CPU now (for non-GL rendering), guest draw calls that are faster than the monitor refresh rate are now consolidated before drawing at vblank, rendering of multiple displays can happen concurrently now
• Fixed rendering to multiple displays on the new renderer backend
• Fixed an issue in QEMU where the vmnet backend uses 100% of CPU when the VM is suspended (Pausing a VM is broken: QEMULauncher uses 100% CPU after pausing VM #4803)
• (iOS) TrollStore: Fixed JIT enable in the HV builds
• (iOS) TrollStore: New option to enable TSO (Total Store Ordering) in QEMU settings (see Highlights for more details)
• (iOS) Restored the default renderer backend to GL. This was changed in v4.1.3 because Metal is faster but the new backend can introduce regressions such as glxgears not working (UTM crashes when running glxgears #4856). As a result, the new backend is now opt-in but is still highly recommended.
• (iOS) Fixed crash when changing VM settings on iOS 14 (crash on any vm settings change #4864)
• (iOS) Fixed crash when starting a VM with UTM SE (UTM SE crashes on QEMU 7.2.0 #4848)
• (macOS) A tooltip will now reveal why suspend functionality is disabled

Changes (v4.1.3)

• Updated QEMU to v7.2.0
• Reworked CocoaSpice renderer to respond faster to GL updates from the guest, should improve frame pacing on GL supported Linux VMs
• Added global setting to change renderer backend, introduce ANGLE Metal as an option (and also the new default for iOS)
• Added global setting to limit FPS which can be used to improve frame pacing for a smoother rendering experience
• Settings: clearly show if the current display hardware supports GPU acceleration
• Wizard: GPU acceleration is now enabled by default when Linux is selected as the operating system
• Fixed crash due to an error with GL_DRAW_COOKIE_INVALID (QEMULauncher crashes on shutdown when using GPU accelerated display adapter (GL_DRAW_COOKIE_INVALID) #4722)
• Fixed deadlock on startup caused by gstosxaudio (Audio Output from VM causes hangs and instability #2364)
• Fixed memory leak when GPU acceleration is enabled (QEMULauncher memory leak #4449)
• Fixed crash in -[MTLResourceList releaseAllObjectsAndReset] (TestFlight: Crash in -[MTLResourceList releaseAllObjectsAndReset] #3519)
• Fixed Mesa issue causing some GNOME desktop to freeze when GPU acceleration is enabled
• Fixed incorrect logic when cloning a VM (Multiple entries in VM list show up when cloning fails #4815)
• Fixed some thread scheduling warning (Investigate ways to avoid priority inversions #4352)
• Localization: updated French (thanks @FRtranslator)
• (iOS) TrollStore build: use com.apple.private.security.no-sandbox instead of com.apple.private.security.no-container on recommendation of other devs and to align with how other apps perform JIT.
• (iOS) Fixed blank screen when choosing "Open" in the wizard (Open files in the wizard shows a blank screen #4842)
• (iOS) Fixed toolbar not auto-hiding before first interaction (Toolbar icon not auto-hiding when touch screen is not used #4844)
• (macOS) New design for global settings (Cmd+,) which better organizes the settings
• (macOS) utmctl: Fixed crash when utmctl help attach runs (utmctl help attach fails with an ArgumentParser error #4817)
• (macOS) utmctl: Fixed utmctl stop with --request and kill (Request shutdown doesn't seem to work (almost instantly stops VM). Works from menu bar. #4850)

Hello, I'm trying to run this app by an alternative method which is to insert the source code in Swift playgrounds and run it, which doesn't work. I was trying to find out if there is a way to use the app without installing stores or possibly malicious things. It gives an error that I can't eliminate (it should be noted that I still don't have much experience in programming) the error is this "The type of target, "ClangTarget" is not compatible" do you have any idea why it may be happening, investigate but I still can't find a way to remove it here is the code that I was using to try to run the app, do not directly export the app since it is a very tedious and long process with which it is easy to get confused and in the end I preferred to open the app from the zip only it gives that error ( the code below ) =

import SwiftUI
import UIKit
import PlaygroundSupport
import Zip

class ViewController: UIViewController, UIDocumentInteractionControllerDelegate {

 override func viewDidLoad() {
     super.viewDidLoad()
    
     // Get the path to the zip file
     guard let zipPath = Bundle.main.path(forResource: "UTM-4.1.6.zip", ofType: "zip") else {
         fatalError("Zip file not found")
     }
    
     // Get the path to the Documents directory
     guard let documentsPath = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first else {
         fatalError("Cannot access the Documents directory")
     }
    
     // Create a temporary directory to unzip the zip file
     let tempDirectory = documentsPath.appendingPathComponent("temp", isDirectory: true)
     try?  FileManager.default.removeItem(at: tempDirectory)
     try FileManager.default.createDirectory(at: tempDirectory, withIntermediateDirectories: true, attributes: nil)
    
     // Unzip the zip file in the temporary directory
     try Zip.unzipFile(URL(fileURLWithPath: zipPath), destination: tempDirectory, overwrite: true, password: nil)
    
     // Get the path to the application file inside the temporary directory
     let appPath = tempDirectory.appendingPathComponent("UTM-4.1.6.app")
    
     // Get the URL to open the app
     let appURL = appPath.absoluteURL
    
     // Open the app with the UIDocumentInteractionController
     let documentController = UIDocumentInteractionController(url: appURL)
     documentController.delegate = self
     documentController.presentOpenInMenu(from: .zero, in: view, animated: true)
    
     // Show the temporary directory in the Swift Playgrounds file panel
     let documentBrowserViewController = UIDocumentBrowserViewController(forOpeningFilesWithContentTypes: ["public.item"])
     documentBrowserViewController.additionalTrailingNavigationBarButtonItems = []
     documentBrowserViewController.allowsDocumentCreation = false
     documentBrowserViewController.directoryURL = tempDirectory
     PlaygroundPage.current.liveView = documentBrowserViewController
 }

 func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {
     return self
 }

}

That's not how UIDocumentInteractionController works and you can't open apps that way. There's probably a dozen reasons why it won't work in Playgrounds but even if you fix all of them, you're not going to be able to launch an app that way.
