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.

iOS 14 unfortunately patched the ptrace() exploit that allowed UTM to run side-loaded on non-jailbroken devices. UTM 2.0 running on iOS 14 requires either jailbreaking or tethering to the Xcode debugger (launch directly from Xcode). To better support future iOS releases, we are deprecating support for non-jailbroken devices. This means that future features may depend on jailbreak and "legacy" UTM will no longer get priority for new features.

As always, please report all bugs to Github


  • Fixed “Could not allocate dynamic translator buffer” on jailbroken devices (#459)
  • Implemented APRR JIT for < iOS 14. This means non-jailbroken devices on < iOS 13.5 (thanks to Psychic Paper) and ALL jailbroken devices get improved JIT. These devices no longer have the 1/2 JIT cache penalty (and can allocate a bit more guest RAM). The kernel instability from improper exit should also no longer affect these devices and you can now terminate UTM by swiping up from the task switcher.
