Hello, I am trying without luck to create a .dmg or .pkg for my electron app that can be opened by any user on a mac. Every time I fail. All is happening by the same pattern. Here is the last try with creating a .pkg instead of .dmg. The app is built and it is signed correctly (I suppose) codesign --verify --verbose=1 dist/mac-universal/VIVIDTIME.app dist/mac-universal/VIVIDTIME.app: valid on disk dist/mac-universal/VIVIDTIME.app: satisfies its Designated Requirement I created a .pkg pkgbuild --root "dist/mac-universal/VIVIDTIME.app" \ --install-location "/Applications/VIVIDTIME.app" \ --identifier "app.vividtime.mac" \ --version "1.1.0" \ --sign "Developer ID Installer: Pavel Bochkov-Rastopchin (2QKDCTR5Y3)" \ dist/VIVIDTIME.pkg pkgbuild: Inferring bundle components from contents of dist/mac-universal/VIVIDTIME.app pkgbuild: Adding component at Contents/Frameworks/Mantle.framework pkgbuild: Adding component at Contents/Frameworks/VIVIDTIME Helper.app pkgbuild: Adding component at Contents/Frameworks/VIVIDTIME Helper (GPU).app pkgbuild: Adding component at Contents/Frameworks/Electron Framework.framework pkgbuild: Adding component at Contents/Frameworks/Squirrel.framework pkgbuild: Adding component at Contents/Frameworks/VIVIDTIME Helper (Renderer).app pkgbuild: Adding component at Contents/Frameworks/VIVIDTIME Helper (Plugin).app pkgbuild: Adding component at Contents/Frameworks/ReactiveObjC.framework pkgbuild: Using timestamp authority for signature pkgbuild: Signing package with identity "Developer ID Installer: Pavel Bochkov-Rastopchin (2QKDCTR5Y3)" from keychain /Users/innrvoice/Library/Keychains/login.keychain-db pkgbuild: Adding certificate "Developer ID Certification Authority" pkgbuild: Adding certificate "Apple Root CA" pkgbuild: Wrote package to dist/VIVIDTIME.pkg
