Hi. I create a dmg for my app (notarized success, it's on Big Sur, Intel), this dmg can drag the app to the applications folder. After copy the app can work on: Big Sur (intel) Big Sur (M1) but it's can't work on High Sierra, this is the message app is damaged and can't be opened. use command to check notarized spctl -a -vv to check my app, it's return accepted. If directly open the app on dmg volume, it's work. It's possible got some problem after copy?

On the macOS 10.14 I created a project(installer) that will install a .KEXT(driver) which was signed by the provider’s company. My installer can install the KEXT to the correct location which is “Library/Extensions”. But it will not work, even after reboot. Then I tried to use the command below, but the OS couldn't find the driver. kextstat Here is component plist for pkg <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <array> <dict> <key>BundleIsVersionChecked</key> <true/> <key>BundleOverwriteAction</key> <string>upgrade</string> <key>RootRelativeBundlePath</key> <string>ThirdPartyOfficial.kext</string> </dict> </array> </plist> Below is what I did. Step1 pkgbuild --identifier "com.xxxx" --root "SrcPath" --install-location "/Applications/XXXX.app" --component-plist "plistPath" "outputPath" Step2 productsign --sign "Developer ID Installer: XXXX" "PkgPath" "NewPkgPath" Step3 xcrun altool --notarize-app --primary-bundle-id "BundleName" --username "XXXXX" --password "XXXX" --file "FilePath" Both CodeSing and Notarize were successful. I don’t know why it will not work. As well as it doesn’t show the “Allow” button in the Settings/Security and Privacy. Does anyone know what I missed?
