Hi guys, I checked this and it can be reproduced on Big Sur(beta), too.

Hi Eskimo, Thank you for your nice reply! But I want to confirm is there a feature list comparison? For example, with Audit log, there are Authentication and authorization (aa) and Login/Logout (lo) events, but there seems be no such events with Endpoint Security now. Is there any suggestion for such parts? Thank you very much!

I am also facing the same problem. Is it possible to whitelist uninstalling system extension by MDM? Any one can help?

Hi guys and @eskimo, We are also having the exact same problem with a growing number of our users. For the recent customer, his macOS is 10.14.6, SIP enabled, our KEXT is notarized and can be loaded after customer reinstall 10.14.6. Customer mentioned that he apply mac security update "2020-005" before issue occurred. But from the release note, it should not be related to missing "restricted" flag. Do you have any idea? Thank you!

Hi @meaton I filled a report:FB8931220, and attached the panic-full-2020-12-03-170845.0003.ips panic report. Please help to check, thank you!

Hi eskimo, Thank you for your response. I do these steps : Use leaks command to get the memory graph Use footprint command to info: `Dirty      Clean  Reclaimable    Regions    Category     ---        ---          ---        ---    ---  925 MB        0 B          0 B      14012    Accounts framework` Use vmmap command to list the vm info, then vm info show addresses `Accounts framework          130e45000-130e56000    [   68K     0K     0K    68K] r--/r-- SM=SHM   Accounts framework          130e56000-130e67000    [   68K     0K     0K    68K] r--/r-- SM=SHM   Accounts framework          130e67000-130e78000    [   68K     0K     0K    68K] r--/r-- SM=SHM   Accounts framework          130e78000-130e89000    [   68K     0K     0K    68K] r--/r-- SM=SHM   Accounts framework          130e89000-130e9a000    [   68K     0K     0K    68K] r--/r-- SM=SHM   Accounts framework          130e9a000-130eab000    [   68K     0K     0K    68K] r--/r-- SM=SHM  ` Then get above traceTrees with the address

Hi eskimo, Thank you very much! I find the description : DEPRECATION NOTICE The audit(4) subsystem has been deprecated since macOS 11.0, disabled since macOS 14.0, and WILL BE REMOVED in a future version of macOS. Applications that require a security event stream should use the EndpointSecurity(7) API instead. On this version of macOS, you can re-enable audit(4) by renaming or copying /etc/security/audit_control.example to /etc/security/audit_control, re- enabling the system/com.apple.auditd service by running launchctl enable system/com.apple.auditd as root, and rebooting. But I want to confirm: with Audit Log, I can get the AUE_LISTEN/AUE_BIND event. I think these events should not be covered by EndpointSecurity, is it right? Will Network Extension cover these events? Thank you!
