Unlike other free virtualization software, UTM was created for macOS and only for Apple platforms. It is designed completely from the ground up for the new style introduced in Big Sur. UTM looks and feels like a Mac app with all the privacy and security features you expect as well.
Free Mac App Store
Under the hood of UTM is QEMU, a decades old, free and open source emulation software that is widely used and actively maintained. While QEMU is powerful, it can be difficult to set up and configure with its plethora of command line options and flags. UTM is designed to give users the flexibility of QEMU without the steep learning curve that comes with it.
UTM is and always will be completely free and open source. The Mac App Store version is identical to the free version and there are no features left out of the free version. The only advantage of the Mac App Store version is that you can get automatic updates. Purchasing the App Store version directly funds the development of UTM and shows your support .
No one here made the rules. We all follow them like you do because we're just users like you are. You need to make a google ID to get anything from the play store. You need an amazon sign in to get anything from Amazon, you need a Microsoft ID to activate a PC and get apps...so Apple is not unique.
"I've been using Anki for two years now, and I just wanted to thank you personally for contributing to the single most obvious improvement in my quality of life. I'm not being hyperbolic: consistent use of Anki has opened more doors for me intellectually than I could have imagined two years ago. And being a poor student, I'll be forever grateful that you've provided this software open-source and free of charge."
With Memory Clean, you can set the app to automatically clean your memory when free memory falls below a defined threshold amount. You no longer have to remember to keep freeing up your memory to keep your Mac running fast.
