First launch

Beta builds are not yet code-signed by Apple or Microsoft. Each OS shows a one-time warning on first launch. Past it once and the OS remembers.

macOS — Gatekeeper warning
  1. Drag Splice CAD.app into Applications.
  2. Right-click Splice CAD in Finder → Open → Open. The choice persists for future launches.
  3. If the right-click route still gets blocked (common on macOS Sequoia and later), open System Settings → Privacy & Security, scroll to the Security section, and click Open Anyway next to the "Splice CAD was blocked" message. Authenticate with Touch ID or your password, then relaunch the app from Applications.
  4. Last resort — clear quarantine attributes from Terminal: 
    xattr -cr "/Applications/Splice CAD.app"
Windows — SmartScreen warning
  1. Run the downloaded .exe installer.
  2. SmartScreen shows "Windows protected your PC". Click More info.
  3. Click Run anyway. The installer continues normally.

SmartScreen reputation accrues with install volume; later releases trigger fewer warnings.

Linux — AppImage and .deb

AppImage (any distribution):

chmod +x Splice_CAD-*.AppImage
./Splice_CAD-*.AppImage

Debian / Ubuntu:

sudo apt install ./splice-cad_*.deb
