+The architectures are **not** interchangeable: an Intel Mac cannot run the

+Silicon run Intel apps, never the reverse). If a release predates the Intel
+build target and has no `x64` DMG, use the

 If the first launch is blocked by macOS Gatekeeper ("OmniVoice Studio cannot be
 opened because the developer cannot be verified"), see the next section — it
 opens with one right-click, no Terminal.
