MimikaStudio v2026.03.11

MimikaStudio v2026.03.11 Release Notes

Release Date: March 24, 2026
Platform: macOS (Apple Silicon)

---

What's New In v2026.03.11

• Fixed the packaged macOS app bundle so the bundled backend starts correctly on first launch from the release DMG.
• Rebuilt the embedded backend/python packaging flow so the final .app is re-signed and verified after resources are injected.
• Kept the existing unsigned-DMG guidance in place for Gatekeeper, while removing the broken sealed-bundle state that caused backend exit-on-start.

---

User Impact

• New DMG installs should no longer fail with Backend process exited before becoming healthy on first launch.
• The bundled backend now survives the initial startup path instead of exiting with code 1 because of an invalid packaged app seal.
• Users still need the documented first-open Gatekeeper/quarantine workaround until the app is signed and notarized.

---

Technical Notes

• Updated scripts/build_dmg.sh to strip copied extended attributes from the finished app bundle.
• Added a final app-bundle codesign --deep pass after embedding backend resources.
• Added strict post-build signature verification so broken release bundles fail during packaging instead of after shipping.

---

Previous Release: v2026.03.10

• Added desktop drag-and-drop import to the Audiobooks workflow, plus resizable/collapsible panels for Documents, Generated Audiobooks, and Upload Voice management.

2. In Applications, right-click MimikaStudio.app and select Open.
3. Click Open in the warning dialog.
4. If macOS still blocks launch, go to: System Settings -> Privacy & Security -> Open Anyway (for MimikaStudio), then confirm with password/Touch ID.

6. On first use, click Download for required models in-app.
