macOS packages

Apple silicon, Intel or Universal?

A DMG or PKG can still target different processors. Check the Mac first, then read the architecture in the official filename.

Catalog checked: 16 current packages

The short answer

Use ARM64 or Apple silicon on M-series Macs, x64 or x86_64 on Intel Macs, and Universal when the project ships one file containing both builds. An Intel-only build may open through Rosetta on Apple silicon, but it should be a fallback rather than the first choice.

Read the architecture before the extension

DMG and PKG describe how the app is delivered. ARM64, x64 and Universal describe which Mac can run the binary.

  1. Apple silicon · ARM64

    For M1, M2, M3, M4 and later Apple chips. Filenames often contain ARM64, arm64 or aarch64.

  2. Intel · x64

    For Macs with an Intel processor. Look for x64, x86_64, Intel or a filename without ARM when the project documents it as Intel-only.

  3. Universal

    Contains Apple silicon and Intel code in one application. It is the simplest choice when the official release offers it.

What official slicer releases publish now

These are exact filenames from the newest stable releases in the archive, not invented package names.

Counts and filenames come from the latest stable release of each official project in the local archive.

Check your Mac in four moves

  1. Open About This Mac

    Read the Chip or Processor line. “Apple M…” means Apple silicon; an Intel model name means Intel.

  2. Match the filename

    Choose ARM64 for Apple silicon, x64 or x86_64 for Intel, or Universal for either. Do this before comparing DMG with PKG.

  3. Keep the old app briefly

    Rename the existing app or keep the old download until the new build opens your profiles and a known project correctly.

  4. Verify the source

    Open the release record and follow its official project-release link. Do not install a same-named file copied to an unrelated download site.

Sources and scope

Processor guidance follows Apple Support. Package availability and filenames are read from the projects’ official GitHub releases; a filename identifies the advertised architecture, not minimum macOS compatibility.
