Update for a Apple system extension?

[BanditDD]

Hello,

MacOS 15.4.1 informs me, that a Apple system extension was updated but not completed because the security settings are too restrictive:

Why can't Apple not update their own extensions? Why should I relax the security settings? And how can I discover which extension was updated? I use MacOS 15.4.1 on a new Mac Studio M4 Max.

Did any of you receive this message?

Best regards,
BanditDD

I don't think it's an extension from Apple.

I use no other software with system/kernel extensions…

From Terminal

systemextensionsctl list

returns nothing?

Only the little snitch network extension - but that is not an extension from Apple

enabled active teamID. bundleID (version) name [state]
* * MLZF7K7B5R at.obdev.littlesnitch.networkextension (6.2.3/7153) Little Snitch Network Extension [activated enabled]

This app + network extension was installed on 2025-03-26 - and needs no reduced system security settings! And the dialog shows "system extension from Apple". Little snitch comes from Objective Development…

Do you have anything in /Library/Extensions/ ?

From @ab22's link above, if AppleMobileDevice.kext is the cause, try to install the latest one and reboot.
