Hey, We also opened a feedback assistant request, and also opened a ticket with Apple Developer Technical Support a while ago that notice the unmount problem also but it was before we pin point the problem to the Network Extension. After a further investigation, we've found out that the root cause of this problem is cause by having a network filter from the NetworkExtension provider on (Specifically we have tested with the NEFilterDataProvider) while having a Xsan volume. The NEFilterDataProvider causing problems for the Xsan, and is stalling the shutdown until we get a panic from watchdog timeout, and only then the mac is fully shutdown. The problem from what we investigated and also talked with you, is that the Xsan process can't unmount the volume and stuck. We have also noticed that if we install a network extension and allow the popup of the network filters, i.e enabled the NEFilterDataProvider the computer is stuck, and the finder is in a non responsive state until a reboot (Also probably due to the fact the Xsan is now in a problematic state). This tests was done on latest versions of MacOs 13 & 14. We have taken a sysdiagnose from the computer while we have tested. Do you familiar with the problem (We got no answer on the feedback assistant)? Thank you, Idan

Hey, we also opened a bug regarding this behavior on April, back when you introduce the new event on MacOs 15.4 The bug ticket is: FB17139326 Starting macOs 15.4 you added a new event for the system extension framework named: tcc_modify The event should be triggered every-time there is a change regarding the tcc db (granted / revoked using various ways). One of the ways you can grant / revoke tcc db permission is by changing the user sqlite with root permissions. You can change various permissions regarding the user for example the apps that allowed to use microphone permissions. It is expected that when granted / revoked permissions using sqlite for microphone we will get notify from the system extension for tcc modify event. but the actual result is that the permission is added without any tcc modify event. We wanted to know if this is intentional that changing the user tcc db with root permissions, using sqlite and not conventional methods (user popup / settings), suppose to not initiate an event, and we should monitor them using other methods. Thank you, Idan
