    v2.4.2-kx1 — macOS (Apple Silicon) Stable

    walterioo released this 2026-07-20 17:57:11 +00:00 | -23 commits to stable since this release

    macOS build (Apple Silicon / arm64) of OrcaSlicer-KX v2.4.2-kx1.

    Upstream (viewit) only publishes Linux and Windows. This release adds the .app compiled for Apple Silicon Macs (arm64).

    Install

    1. Download OrcaSlicer-KX-v2.4.2-kx1-macOS-arm64.zip and unzip it → OrcaSlicer.app.
    2. Move it to /Applications (rename to OrcaSlicer-KX.app if you also keep the official OrcaSlicer).
    3. First launch (Gatekeeper): the build is not signed/notarized, so macOS quarantines it after download. Right-click → Open (or System Settings → Privacy & Security → "Open Anyway"). After you allow it once, it opens normally.
      • Terminal alternative: xattr -dr com.apple.quarantine /Applications/OrcaSlicer-KX.app

    Stop repeated folder / keychain-password prompts (recommended)

    Because the app is only ad-hoc signed (not notarized), macOS may keep re-asking for the keychain password or folder access. To make those grants stick, sign it once with a stable identity that is local to your Mac:

    1. Download macos_codesign_local.sh (attached to this release), or get it from the repo.
    2. After installing the app, run it once: 
      chmod +x macos_codesign_local.sh
./macos_codesign_local.sh

    It creates a self-signed code-signing identity on your own machine (login keychain — no admin password, nothing shared or uploaded) and re-signs the installed app with it. On the next launch, allow the folder prompts and click "Always Allow" on the keychain prompt once; macOS then remembers them.

    Runs on any Mac — it generates that machine's own certificate; the script itself contains no certificate. If you ever rebuild the app, re-run it (it reuses the same identity).

    Details

    • Architecture: arm64 (Apple Silicon). Does not run on Intel; for Intel, rebuild with -a x86_64.
    • Includes macOS-specific fixes not present in the upstream tag (use-after-free crash on quit, Bambu network-plugin SIGABRT on quit) — built from branch macos-notes-v2.4.2.
    • How it was built / how to rebuild: see BUILD_MAC_KX.md in the repo.
    • Signature: ad-hoc (not notarized).
    • SHA-256 (zip): ffb39fca9c8bbcad33ea92191512c30f0ccd11cf5b6959367bcb569879aa6aec
