So basically the problem starts in system preferences -> security & privacy. There is no allow button at all. I received letter from Apple that app is successfully notarised. Digging into the problem I've found that problem is with kext. So after sudo kextutil /pathtokext I see such errors in terminal: Filesystem error: Invalid ownership (503:20) should be (0:0) on /private/var/db/KernelExtensionManagement/Staging/com.name.filesystems.P88h7Z/name.kext/Contents Filesystem error: Invalid ownership (503:20) should be (0:0) on /private/var/db/KernelExtensionManagement/Staging/com.name.filesystems.P88h7Z/name.kext/Contents/_CodeSignature Filesystem error: Invalid ownership (503:20) should be (0:0) on /private/var/db/KernelExtensionManagement/Staging/com.name.filesystems.P88h7Z/name.kext/Contents/_CodeSignature/CodeResources Filesystem error: Invalid ownership (503:20) should be (0:0) on /private/var/db/KernelExtensionManagement/Staging/com.name.filesystems.P88h7Z/name.kext/Contents/MacOS Filesystem error: Invalid ownership (503:20) should be (0:0) on /private/var/db/KernelExtensionManagement/Staging/com.name.filesystems.P88h7Z/name.kext/Contents/MacOS/name Filesystem error: Invalid ownership (503:20) should be (0:0) on /private/var/db/KernelExtensionManagement/Staging/com.name.filesystems.P88h7Z/name.kext/Contents/Info.plist" UserInfo={NSLocalizedDescription=Validating extension failed: Kext name v2080.20 in executable kext bundle bundle name at name.filesystems.P88h7Z/name.kext:
