UTM works on all devices running iOS 11 or higher if jailbroken. UTM can also be run tethered to Xcode on non-jailbroken devices but this is only recommended for advanced users. UTM runs untethered on non-jailbroken devices with limited compatibility depending on your iOS version and device processor. See the list below for more details.
If you are running iOS 11, 12, or 13: UTM does not require a jailbreak to use, but you must sideload it. If you are new to sideloading, it is a way to use a developer’s certificate to load unapproved apps on a non-jailbroken iOS device. There are a few limitations to sideloading:
- Free developer accounts must re-sign every 7 days
- Paid developer accounts must re-sign every 1 year
The recommended way for non-jailbreak users is to use AltStore which manages re-signing automatically.
If you are running iOS 14.2, 14.3: UTM works with sideloading (non-jailbroken) if your device has an Apple A12 chip or newer. Otherwise, you need to be jailbroken.
If you are running iOS 14.0, 14.1, 14.4, or higher: UTM only works if you are jailbroken.
Note: at this time, 3rd party repos require a beta of AltStore which is available only to the developer’s Patreon supporters. When installing from the repository, you can recieve update prompts from AltStore.
For non beta-testers, the public release of AltStore lacks the ability to add repositories and check updates but can still manage re-signing automatically.
There are many “cloud” signing services including AppCake that do not work with UTM because they use the wrong kind of signing certificate. If you get a crash or a black screen while trying to start a VM, it is likely that your signing certificate was invalid.
You can check if you have the right signing certificate by going to
Settings -> General -> Profiles & Device Management. If the certificate used for signing UTM is listed under
Developer App, then it is good. If it is listed under anything else such as
Enterprise App, then it is the wrong certificate.
UTM requires AppSync Unified which can be found on Karen’s Repo. You need to add both repositories to your package manager (Cydia, Sileo, Zebra, etc.) to install UTM.
