2 years ago

UTM 2.0 includes a redesign of the frontend for iOS 14 and introduces support for macOS 11. Due API limitations, the new design will not be available for iOS 13 and below. That means any feature that depends on the new design will also not be back-ported to iOS 13. Launching UTM 2.0 on iOS 14 will show the new design and launching UTM 2.0 on iOS 13 and below will show the old design. UTM 2.0 also updates the QEMU backend from 4.2.0 to 5.2.0 (for all supported iOS versions).

Installation instructions differ depending on what version of iOS you are running:

  • iOS 11-13: You can install and run UTM using any version of AltStore (recommended) or iOS App Signer.
  • iOS 14: You must either be jailbroken or follow the tethered launch instructions every time you launch UTM. Note that the jailbroken instructions are currently outdated. If you have a good guide, please let us know.
  • iOS 14.2: You can use either AltStore (>= 1.4.2) or iOS App Signer. Note A11 and older devices are not supported by this method and must be jailbroken or use tethered launch.

As always, please report all bugs to Github


  • Updated QEMU backend from 5.1.0 to 5.2.0-rc3 with additional patches for virtualization support on Apple M1 Macs
  • Potentially VM breaking change: For newly created VMs, -device virtio-gpu-pci is no longer added by default to virt machines (ARM64). This is due to newer versions of OVMF not supporting the option. On existing VMs, the option is moved to QEMU custom arguments.
  • An issue prevented auto-detection of CPU cores on supported configurations (weak on weak)
  • Correct missing names for some network cards (#706)
  • Some minor description changes in System settings
  • (iOS 14) Removable drives and shared directory works outside of the sandbox
  • (macOS) Bug where new VM button was not working (#704)
  • (macOS) Fix mouse dragging in capture mode
  • (macOS) Disabled App Sandbox since a macOS bug prevents Hypervisor.framework from working inside an inherited Sandbox (FB8921623)

Known Issues

  • Cannot import any drives/ISO: there is a bug in iOS where an invalid "application-identifier" entitlement causes the file picker to not work. A fix for iOS App Signer is submitted and can be manually compiled. If you are using AltStore, you need use a free (not paid) developer account.
  • Starting a VM goes to a black screen on iOS 14: you need to sign UTM with a "development" certificate. If you used a 3rd party signing service, it is probably signed with the wrong certificate. If you signed UTM yourself, make sure you chose a "development" certificate and in iOS App Signer, "No get-task-allow" is unchecked.

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