v4.0.4 (Beta)

Remember to back up your VMs before running a beta release of UTM!

Highlights

• Multiple display and headless display is now supported for QEMU machines. You can configure 0 or more displays as well as 0 or more builtin terminal consoles. On macOS, a new window will be created for each display and builtin terminal. On iOS, you can create multiple windows (iPad) as well as plug in an external display or AirPlay (iPad or iPhone) and assign outputs to each window.
• Ventura updates to Virtualization. macOS Ventura introduces new features to Virtualization.framework that is now integrated into UTM. You can now create GUI Linux VMs with EFI boot. Clipboard sharing and directory sharing now works with macOS Ventura guests. Rosetta x86_64 emulation is supported for Linux VMs on Apple Silicon.
• VirtFS sharing for QEMU. This can be enabled in the VM settings under Sharing. You can mount the tag "share" in the VM. Note that macOS UID are numbered differently than Linux so you may need to set up your guest to have permission to access the shared directory.
• Easier Windows 10/11 installation and Windows guest tools downloader. You can now download and mount the Windows drivers and guest tools ISO image with a single click (macOS: disk icon in VM window, iOS: 3D touch context menu on home screen). Additionally, the ISO now include an "Autounattend.xml" which is recognized by the Windows 10/11 installer. When mounted to a second CD drive, the installer will install the correct drivers, bypass secure boot/TPM requirements, and launch the SPICE tools installer on first login.
• (macOS) Resize QEMU disk images. In the drives settings page, you can now expand the size of the QCOW2 disk image.
• (iOS) QEMU Virtualization for M1 iPad. With the release of TrollStore, you can now enable Hypervisor on iOS. Note that only M1 hardware and kernel have support for Hypervisor and it has only been tested on iOS 15.

Notes

• iOS 14 and macOS 11.3 are the new minimum supported systems. 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.
