🎊Happy New Year!🎊

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
• The configuration backend has been massively rewritten. Please backup all VMs prior to updating as you will not be able to re-open VMs saved by UTM v4 on older versions of UTM if you decide to downgrade.

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 (#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 (#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 (#4864)
• (iOS) Fixed crash when starting a VM with UTM SE (#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

• Fixed 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 (#4815)
• Fixed some thread scheduling warning (#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 (#4842)
• (iOS) Fixed toolbar not auto-hiding before first interaction (#4844)
• (macOS) New design for global settings (Cmd+,) which better organizes the settings
• (macOS) utmctl: Fixed crash when utmctl help attach runs (#4817)
• (macOS) utmctl: Fixed utmctl stop with --request and kill (#4850)

Changes (v4.1.2)

• Localization: updated Spanish (Latin America) (thanks @JezerM)
• Localization: updated Japanese (thanks @MMP0 and @skyarrow87)
• Localization: updated Chinese Simplified (thanks @changanmoon)
• (iOS) Fix new VM wizard not appearing on < iOS 14.5 (#4776)
• (macOS) Implement OSA interface for AppleScript
• (macOS) Introduce a CLI application (UTM.app/Contents/MacOS/utmctl) that wraps around the OSA interface for automation
• (macOS 13+) New settings option to enable a menu bar extra icon for controlling VMs
• (macOS 13+) New settings option to disable the dock icon
• (macOS) Fix various alignment issues in settings (#4596) (thanks @JezerM)
• (macOS) Fix a crash when the pasteboard is updated (#4745)
• (macOS) Support custom resolutions for Apple Virtualization VMs
• (macOS) Fixed a UI freeze when canceling out of the settings for an Apple Virtualization VM

Changes (v4.1.1)

• Fixed launching SPARC machines (#4575)
• Fixed an error when attempting to save a VM where one of its removable drives is linked to a file that has been deleted
• Fixed IPSW/.utm download failing when the device goes to sleep (the download should resume after wake up)
• Restored scroll bars when system is set to always show scroll bars. Added a new SwiftUI crash workaround thanks to @evelyneee.
• Display all sizes in binary (MiB/GiB) mode in order to be consistent (#4396)

Issues

Please check the full list on Github and help report any bug you find that is not listed.

Installation

• iOS
• macOS

1. Hypervisor on iOS requires an M1 iPad.
2. Enabling JIT may require a separate JIT enabler such as Jitterbug or Jitstreamer.
