I have obtained the permission of driverkit, and the compilation and notarization passed. When I activate the dext in application, it will report Error : Domain=OSSystemExtensionErrorDomain Code=8 "Invalid code signature or missing entitlements". I searched a lot of information on the forum and followed the instructions, among which is disable SIP. My App's entitlements is : <dict>         <key>com.apple.security.app-sandbox</key>         <true/>         <key>com.apple.security.files.user-selected.read-only</key>         <true/>         <key>com.apple.developer.system-extension.uninstall</key>         <true/>         <key>com.apple.developer.system-extension.install</key>         <true/>         <key>com.apple.security.get-task-allow</key>         <true/> </dict> </plist> dext's entitlements is : <dict>         <key>com.apple.developer.driverkit</key>         <true/>         <key>com.apple.developer.driverkit.transport.usb</key>         <array>                 <dict>                         <key>idVendor</key>                         <integer>2414</integer>                 </dict>         </array>         <key>com.apple.security.app-sandbox</key>         <true/>         <key>com.apple.security.get-task-allow</key>         <true/> </dict> Can some one help me ?
