Hi, I'm adding a Content Filtering (FilterDataProvider) on macOS to an existing app and using MDM to avoid user interaction. I start by pushing the following payloads to my machine: com.apple.system-extension-policy com.apple.webcontent-filter And then installing notarized pkg containing my app and the NE. Inspecting the system logs shows the following error: neagent Failed to find a com.apple.networkextension.filter-data extension inside of app com.company_name.app_name.daemon And calling submit(request: .activationRequest(forExtensionWithIdentifier: bundleId, queue: queue)) results in: Missing entitlement com.apple.developer.system-extension.install Installing from Xcode on a SIP disabled machine works fine and both NE and CF are working as expected. I followed the steps mentioned here https://developer.apple.com/forums/thread/737894 however the embedded entitlements already contained -systemextension suffix so I'm not sure if re signing and the subsequent steps are needed. I also double checked that com.apple.developer.system-extension.install is present, certificates are not expired and that get-task-allow is not present in the embedded profile. Here is what my release entitlement file looks like: <?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"> <dict> <key>com.apple.developer.networking.networkextension</key> <array> <string>content-filter-provider-systemextension</string> </array> <key>com.apple.security.application-groups</key> <array> <string>com.company_name.app_name.network-extension.content-filter</string> </array> </dict> and my release app entitlement: <?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"> <dict> <key>com.apple.developer.endpoint-security.client</key> <true/> <key>com.apple.developer.networking.networkextension</key> <array> <string>content-filter-provider-systemextension</string> </array> <key>com.apple.developer.system-extension.install</key> <true/> </dict> </plist> redacted logs @eskimo may I ask for your help here!
