Tired to use my special qemu(aarch64) on UTM(x86_64)

[Kuroshimacat]

I use the latest UTM and macOS15 with intel cpu, I'd like to use my special qemu version(aarch64) and keep the aarch64 in utm, I tried to replace a qemu(aarch64) in Frameworks with my qemu, But failed, what should I do?

macOS will refuse to load your modified UTM.app because it correctly detects that it has been tampered with.

Your best bet is to build UTM following these general instructions: https://github.com/utmapp/UTM/blob/main/Documentation/MacDevelopment.md. For the "./scripts/build_dependencies.sh" step, use -q to point to your modified QEMU source tree instead. Note that even with this method some UTM features (such as bridged networking) will not work unless you get your built application notarized by Apple.

To add to this, our fork is different enough from upstream QEMU that you have to pick your changes and put it on top of our fork for it to work.
