Signed and notarized — download the .dmg, open it, and drag UTM Studio into Applications. No Gatekeeper warning, no right-click bypass needed.
Fixed
- Apple Events were being silently blocked on the signed/notarized build — affecting v1.0.0 and v1.0.1 for anyone using the actual downloaded release (ad-hoc dev builds were never affected). Hardened runtime, required for notarization, blocks an app from sending Apple Events at all unless it explicitly carries the
com.apple.security.automation.apple-eventsentitlement. Without it, utmctl's calls to control UTM failed instantly with a missing-entitlement error, and macOS never even showed the normal "UTM Studio wants to control UTM" consent prompt — so VMs looked invisible, New Client failed, and there was nothing to grant. Diagnosed via a user's own investigation of System Settings → Privacy & Security → Automation, and confirmed with the exacttccdlog line pointing at the missing entitlement.
If you installed v1.0.0 or v1.0.1 and VMs never showed up: install this version instead. On first launch it should now show a real system prompt — "UTM Studio" wants to control "UTM" — click Allow.
