github utmapp/UTM v3.2.1
v3.2.1 (Beta)

latest releases: v4.1.5, v4.1.4, v4.1.3...
pre-release9 months ago


iOS: Visit for the most up to date installation instructions.
macOS: Download "UTM.dmg" below and copy the contents to your /Applications directory.


  • QEMU 7.0.0: The backend has been updated to the latest release. Check out for more details. Additionally, other backend components such as SPICE GTK, libusbredir, and more have also been updated.
  • Reclaiming space: the host will attempt to TRIM any page of all zeros when committed to the QCOW2 disk image. Additionally, a new button in disk settings will allow you to re-convert a disk image to reclaim space (of all-zero pages) as well as compress an existing disk image (macOS 12+ only). Note compression is only done statically which means when the guest modifies a sector, it will be stored uncompressed just like before.


  • (iOS) UTM v3.2.x will be the last update to support iOS 11-13. If you are still running those versions, please make sure you report any issues now so they can be fixed by the final release of v3.2.x. After that, iOS 14+ will be required to run future versions of UTM.
  • In v3.2.0, if you added highmem=on to your QEMU Machine Properties as a workaround, please remove it after updating. If you did not use v3.2.0, you can ignore this.

Changes (v3.2.1)

  • Fixed boot of RISC-V virt platform (thanks @wegank)

  • (macOS) Added option to reclaim unused space from disk image and to compress a disk image (macOS 12+ only)

Changes (v3.2.0)

  • Checkbox for "Import VHDX Image" in the wizard now works correctly again (#3760)

  • (iOS) Fixed an issue in the legacy view where "invalid identifier" error may show up on a newly created VM (#3872)
  • (macOS) Fixed crash when changing display settings while the VM window is open (but stopped) (#3925)

  • (macOS) Prevent allowing rapid clicking of pause/resume which may lead to VM corruption (#3629)
