• (macOS) Fixed sending simultaneous mouse button presses (#7068)
• (macOS) utmctl: Add version command to detect current UTM version
• (macOS) Settings: New option to disable key swapping on ISO keyboards (#6976)
• (macOS) Settings: New option to randomize network MAC addresses on clone (#7035)

Changes (v4.7.1)

• New Liquid Glass icon thanks to @forcequitOS
• Added App Intents for VM operations (#6245)
• Added UEFI boot support for RISC-V64 and LoongArch64. This allows Ubuntu for RISC-V64 to work out of the box. (#7183)
• QEMU PPC: Disable bootindex when boot-device is used in prom-env. This allows Yellow Dog Linux for PPC to work out of the box. (#6436)
• QEMU x86_64: Fixed floppy boot order configuration for other PC models (isapc, i440fx) (#7166)
• QEMU PPC/M68K: Includes classicvirtio drivers to support cursor input without capture and directory sharing (#6520)
• QEMU M68K: Fixed virtio drive config (#7008)
• Fixed a rare crash after stopping VM due to a race condition in libusb
• Home: improve screenshot contrast in Dark Mode (#6894)
• Config: Fixed a crash when trying to enter a large size value when creating a new drive (#7295)
• Config: Corrected the default host IP address in port forwarding config to "0.0.0.0" when it incorrectly displayed "127.0.0.1" (#7132)
• Keyboard Shortcuts: Create custom combinations of keyboard shortcuts from either Settings -> Input or via the Keyboard icon in the VM (press and hold on iOS/visionOS). This will allow you to easily send key commands such as Ctrl+Alt+Del or Stop+A to the VM. (#5698, #6310, #6757)
• Wizard: New option to import an existing drive image when setting up a Linux VM. This allows Ubuntu for RISC-V64 to work out of the box. (#7183)
• Wizard: New option to create a serial port only Linux VM. This allows Ubuntu for RISC-V64 to work out of the box. (#7183)
• Wizard: Removed VHDX import option because Microsoft now provides ARM64 ISO images. Note: You can still create manually import an VHDX after creating a new VM.
• Wizard: New template to create classic Mac OS VMs for M68K and PPC (#3504, #6890)
• Wizard: Most common and supported machines for emulation are now listed prominently with the full list of supported QEMU architectures/targets hidden behind an "Expert" mode. This is necessary because most of the QEMU targets are not properly supported by the wizard anyways and does not generate a bootable config. They usually require a lot more manual tinkering. The page order of the wizard is also tweaked so the hardware config comes before the boot config now.
• Localization: Updated Chinese (Hong Kong, Simplified) (thanks @changanmoon)
• (iOS SE) Fixed a crash when launching ArchLinux due to mis-handling of REV32
• (iOS SE) Fixed a crash when the first instruction executed is a goto
• (iOS SE) Removed ARM32, RISC-V32, and added M68K. There is little use for ARM32 and RISC-V32 as they cannot boot anything useful that cannot also be booted by the 64-bit variant (which is still included). If you have a counter example of this, please open an issue on GitHub and we can consider re-adding it back in the future. However, removing these will make the app size a lot smaller. M68K is added to support classic Mac OS.
• (macOS 11) Fixed guest tools mounting (#7297)
• (macOS 11) Fixed stop button not working (#7298)

• Keyboard Shortcuts: Create custom combinations of keyboard shortcuts from either Settings -> Input or via the Keyboard icon in the VM (press and hold on iOS/visionOS). This will allow you to easily send key commands such as Ctrl+Alt+Del or Stop+A to the VM. (#5698, #6310, #6757)
• Wizard: New option to import an existing drive image when setting up a Linux VM. This allows Ubuntu for RISC-V64 to work out of the box. (#7183)
• Wizard: New option to create a serial port only Linux VM. This allows Ubuntu for RISC-V64 to work out of the box. (#7183)
• Wizard: Removed VHDX import option because Microsoft now provides ARM64 ISO images. Note: You can still create manually import an VHDX after creating a new VM.
• Wizard: New template to create classic Mac OS VMs for M68K and PPC (#3504, #6890)
• Wizard: Most common and supported machines for emulation are now listed prominently with the full list of supported QEMU architectures/targets hidden behind an "Expert" mode. This is necessary because most of the QEMU targets are not properly supported by the wizard anyways and does not generate a bootable config. They usually require a lot more manual tinkering. The page order of the wizard is also tweaked so the hardware config comes before the boot config now.
• Localization: Updated Chinese (Hong Kong, Simplified) (thanks @changanmoon)
• (iOS SE) Fixed a crash when launching ArchLinux due to mis-handling of REV32
• (iOS SE) Fixed a crash when the first instruction executed is a goto
• (iOS SE) Removed ARM32, RISC-V32, and added M68K. There is little use for ARM32 and RISC-V32 as they cannot boot anything useful that cannot also be booted by the 64-bit variant (which is still included). If you have a counter example of this, please open an issue on GitHub and we can consider re-adding it back in the future. However, removing these will make the app size a lot smaller. M68K is added to support classic Mac OS.

Installation

• iOS
• macOS

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

Highlights

• QEMU v10.0.2 The backend has been updated to the latest upstream QEMU which brings with it a variety of bug fixes and performance improvements.
• Liquid Glass UTM adopts the Liquid Glass design on *OS 26.

Notes

• (iOS) iOS 26 breaks the technique that AltJIT and similar tools use to enable JIT. Do not update to iOS 26 if you want to use the JIT supported version of UTM.

Installation

• iOS
• macOS

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

Highlights

• QEMU v9.1.2 The backend has been updated to the latest upstream QEMU which brings with it a variety of bug fixes and performance improvements.
• (macOS 15) Nested virtualization for Linux Linux VMs using Apple Virtualization backend on macOS 15 and M3 or newer will now have nested virtualization enabled by default.
• (macOS 15) Total Store Ordering for QEMU VMs using QEMU backend on macOS 15 can now enable TSO (in QEMU settings) at the hypervisor level. When TSO is enabled on a guest operating system that is aware of the system register (i.e. Rosetta for Linux), performance of Intel emulation within the guest can be greatly improved. Note that if the guest kernel supports dynamically toggling TSO, you do not need to enable this.
• (macOS 15) Improved macOS guest support The last window size (including full screen size) will be restored when the guest supports dynamic resolution. Removable drives and shared directories can now be ejected and changed while the macOS VM is running. Copy/paste synchronization between macOS 15 guest and host now works when the guest tools are installed (from the CD icon in the toolbar).

Notes

• (macOS) There is a known issue with macOS 15.0 and 15.0.1 where accesses to files will fail due to a permission error. This issue has been resolved with macOS 15.1.
• (macOS) There is a known issue on M4 series of Macs where virtualization fails for macOS guests older than 13.4. The issue has been resolved with macOS 15.2.
• The default CPU for x86_64 emulation and virtualization will now try to match the architecture of your system or the highest architecture that QEMU supports. For example, a 2016 MacBook Pro or newer will now emulate a "Skylake" based processor instead of a generic x86_64 processor. This should improve compatibility and performance of newer operating systems but may cause issues with older operating systems. If you run into issues, you can manually change the CPU model to an older one in the VM's System settings.
• v4.6.5 reverted a change from v4.6.4 due to reports of crashes and kernel panics on some machines. As a result, there will be issues when upgrading to Windows 11 24H2 where the screen will go black. An alternative fix with an updated driver will be provided as soon as possible, but for now if you plan to upgrade to Windows 11 24H2, it is recommended you do it from v4.6.4 before updating UTM.

Changes (v4.6.5)

• Reverted virtio-ramfb changes from v4.6.4 due to some users experiencing crashes and kernel panics. An alternative fix to the black screen issue will come in a Windows Guest Support driver update in the future. Until that is released, issue #6332 and #6883 will be unfixed. (#6919)

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 or newer.
2. Enabling JIT may require a separate JIT enabler such as Jitterbug or Jitstreamer.

Highlights

• QEMU v9.1.0 The backend has been updated to the latest upstream QEMU which brings with it a variety of bug fixes and performance improvements.
• (macOS 15) Nested virtualization for Linux Linux VMs using Apple Virtualization backend on macOS 15 and M3 or newer will now have nested virtualization enabled by default.
• (macOS 15) Total Store Ordering for QEMU VMs using QEMU backend on macOS 15 can now enable TSO (in QEMU settings) at the hypervisor level. When TSO is enabled on a guest operating system that is aware of the system register (i.e. Rosetta for Linux), performance of Intel emulation within the guest can be greatly improved. Note that if the guest kernel supports dynamically toggling TSO, you do not need to enable this.
• (macOS 15) Improved macOS guest support The last window size (including full screen size) will be restored when the guest supports dynamic resolution. Removable drives and shared directories can now be ejected and changed while the macOS VM is running. Copy/paste synchronization between macOS 15 guest and host now works when the guest tools are installed (from the CD icon in the toolbar).

Notes

• (macOS) There is a known issue with macOS 15.0 and 15.0.1 where accesses to files will fail due to permission error. This issue has been resolved with macOS 15.1.
• (macOS) There is a known issue on M4 series of Macs where virtualization fails for macOS guests older than 13.4. The issue should be addressed by Apple in a future update. (#6794)
• The update to QEMU v9.1.0 will likely introduce new issues and regressions. If you experience any problem (crashes, performance, errors) that was not evident in v4.5.x, please open an issue and provide all the requested information. It would also be helpful if you can provide a reproducible example and note the last version of UTM where it worked properly.
