Reproduction steps

It seems that both the current stable and beta versions of Cura are still only build for Intel / x86_64 architecture.

This causes significant performance issues as it has to be run in the Rosetta emulator on macOS.

Given that ARM / Apple Silicon has been out for 3 years now and all modern Apple machines are no longer Intel based - Cura should be built for native ARM.

Cura is the only intel-only binary still running on my machines and the differences is very noticeable.

If Cura's CI system cannot build ARM packages, it would be incredibly helpful if the build scripts / instructions worked for ARM so users could optionally build their own packages.

Actual results

Cura runs in emulated Intel x86 mode with poor performance.

Expected results

Cura to run in native mode, not emulated.

Additional information & file uploads

This is somewhat related to #11841 with the addition that it's not only beta builds - but the production stable builds that aren't created properly.

cc/ #8795, #12244, #15161, #14640, #10015 and probably others.

M1 build of 5.4.0, for others that are waiting, the thread if very long so this link will go directly to it.

#11841 (comment)

I'm in the process of setting up the workflows and hooking up the physical self-hosted runner for building Cura for the M1.

Can people try the binaries in this run, which are compiled for the native M1's: https://github.com/Ultimaker/Cura/actions/runs/5906663040

• UltiMaker-Cura-5.5.0-alpha+cura_8415_3dcba6-macos-ARM64-pkg

I am mostly curious if these run on older MacOSes

At least on newest (Sonoma M1) — works.
