We are happy to announce that UTM SE is available (for free) on iOS and visionOS App Store (and coming soon to AltStore PAL)!. Shoutouts to AltStore team for their help and to Apple for reconsidering their policy.

UTM is now running on Vision Pro (simulator)! Still need to implement input devices but here's a sneak peek.

Reminder of what is possible if virtualization was allowed in the App Store.
UTM running Windows 10 on an M1 iPad Pro (virtualized at full speed) TrollStore running on iOS 15.0-15.1.1 and an M1 iPad is needed. IPA release is coming soon but you can build it yourself from source right now.

BAD NEWS: Apple removed Hypervisor support from XNU in iOS 16.4. Here is a diff of iOS 16.3.1 and iOS 16.4. What this means is that even if a jailbreak/TrollStore comes out for iOS 16.6.1/17.0, there will not be UTM virtualization support, even on M1/M2 iPads.

Hypervisor works on iPhone 14 Pro with TrollStore 2 (< iOS 16.4 only). Also working:.- USB devices.- AirPlay to an external display.- Some 3D acceleration on Linux only.
Succesfully installed Windows 11 arm64 via NATIVE virtualization on my iPhone 14 Pro Max via @utmapp.Bootup time is roughly 25 secs from the poweroff state to the desktop.

PSA: Early report shows that in iOS 18.4, Apple may have blocked JIT enablement through get-task-allow, the technique used by AltJIT, SideJIT, Jitterbug, and similar solutions. Avoid updating to iOS 18.4 until there is more information.

Move over Parallels and VMware. QEMU + UTM runs Windows 10 ARM fully virtualized on Apple M1. Be warned, it’s still a bit rough but we’re working hard on it!

Jitterbug is an iOS app that lets you to wirelessly connect to another iOS device (neither are jailbroken) and then launch an app on the connected iOS device with JIT enabled.

Do not update to iOS 14.4 if you wish to continue using UTM. There will not be any workarounds. Future releases of UTM for iOS will focus on jailbroken devices unless Apple’s App Store policy changes. UTM for AltStore will continue to be supported for < iOS 14.4.

UTM v4.5.2 is out with support for UTM Server, a way to do remote desktop from iOS/visionOS to your VM running on macOS. You can get the free client on the App Store: (Also includes big fixes and other quality of life changes.).

Is getting a Windows 11 iso too much hassle? We made a 1-click solution for fetching the latest build from UUPdump. No Homebrew or Terminal script needed! And it’s free and open source!

UTM v4.1.3 is out… and it’s a big one. The rendering backend has been massively reworked and GPU acceleration on Linux is no longer “experimental”. Lots of bug fixes all around. Oh and QEMU is updated to 7.2.0.

PSA: If you have an M1 iPad running iOS 15.4.1 or lower, do NOT update. After Linus Henze releases fugu15 in October, we will try to port UTM with hypervisor to it.

Excited to announce UTM is now available in the Mac App Store! The DMG download will always be 100% free and the MAS version is identical to the free version and all profits will directly support UTM development.

JIT works again on iOS 14.2 (all devices, paid or free accounts). Three changes to AltStore are needed. (cc @rileytestut @altstoreio ).

Deleted a tweet about Apple removing kernel Hypervisor support in iOS 16. We jumped to conclusions based on incomplete information and we apologize for the misinformation. However, the state of UTM Hypervisor support on iOS 16 remains unchanged until a jailbreak is released.

UTM v4.4.5 is out for TrollStore users. JIT should be fixed and virtualization now works on iOS 16 (only on compatible firmware + devices, read release for more details). No changes are made for macOS and non-TrollStore users so feel free to skip this one if that applies to you.

Reminder that with today's TrollStore 2 release and future install methods up to 17.0, you are limited to JIT on 16.4 and beyond. Only 16.3.1 and below supports HV (which would only include M1 and now M2 iPads).
BAD NEWS: Apple removed Hypervisor support from XNU in iOS 16.4. Here is a diff of iOS 16.3.1 and iOS 16.4. What this means is that even if a jailbreak/TrollStore comes out for iOS 16.6.1/17.0, there will not be UTM virtualization support, even on M1/M2 iPads.

My apologies for not testing this before saying it is safe to update to 16.6.1/17.0 (if you do not have JB/MDC support). I checked on 16.0 and didn't think they would remove it in a .4 release.

People seem to be surprised at Apple Silicon performance but I’ve been testing QEMU on 2018 iPad because my 2018 Intel machine boots Windows much much slower (without virtualization).

UTM v2.0.10 is out with many macOS bug fixes (and minor iOS ones). It should now work on M1 Apple Silicon macs!

PSA: do not upgrade to 17.0.1 or 16.7.
I'd say avoid 17.0.1 and 16.7 for good measure and don't come crying back to me later, the CVE entry is similar to the one of the CoreTrust bug. But whether it's actually powerful enough to bring back TrollStore remains to be seen, I'm sceptical for now.

Update: Apple has reached out and clarified that the notarization was rejected under rule 2.5.2 and that 4.7 is an exception that only applies to App Store apps (but which UTM SE does not qualify for).

In case it wasn't clear, if you want UTM virtualization support on iOS for M1/M2 iPads or A14+ devices, stay on 16.3.1 or below (for a future jailbreak/TrollStore). (If you are on any older chip, there is still no hardware support.).

Jitterbug v1.3.1 is released with support for TrollStore installed apps. This allows you to launch UTM (Hypervisor) with JIT support as well. FYI Jitstreamer should work too.

PSA 2: if you are currently using TrollStore AND would like the possibility of updating to a potential next TrollStore, you need to do a delay OTA to iOS 17.0: To be clear, do NOT update to iOS 17.0 yet. Delay OTA gives you an opportunity to do so later!.

iOS 14.2 is out and guess what? UTM works again without Xcode tethering! (At least on iPhone 12, haven’t tested other devices yet) It likely will be gone by iOS 14.3 so make sure you upgrade before then.

Apologies for the incorrect information posted yesterday regarding different iOS 14.2 builds and their compatibility with the new JIT workaround. That turned out to be not true but we are still investigating why some users can’t get JIT to work while others can.

@rileytestut Windows 7 boot time in QEMU almost improves exactly as much as GB single threaded score each generation. Emulation is a good use case for raw CPU power.

What I would LOVE to try is iOS 15 jailbreak + hacking this framework in.
Apple's Developer site has documentation for booting macOS 12 as a guest in Virtualization.framework on Apple Silicon. There's more documentation if you read the headers.
