macOS requires stripping the quarantine attribute on downloaded bundles. 
please execute macOS-install.command in finder


Or it can be done Manualy:
Quarantine bypass:
Right-click → Open (Gatekeeper dialog) OR xattr -dr com.apple.quarantine

You can do it the GUI way (right-click each bundle → Open → "Open" in the Gatekeeper dialog), but you'd need to do that three times (once per bundle). The xattr command does it in one shot and is faster. Either method works; it's just a trade-off between clicking through dialogs and running a single terminal command.

Key point: The AU artifact is ConstellationsSequencer-AU-macOS, and it contains a .component, which is the one Logic loads.
