Interactions Between Existing Kernel Extensions And SystemExtensions ?

I am seeing a situation where the activation of a SystemExtension followed by the enabling of the DNSProxy Network Extension that it hosts resultsin a kernel panic which seems to be being triggered by a third-party kernel extension.


Once the kernel panic has occured it reoccurs every time the machine is re-booted until the SystemExtension is removed.


If the third-party kernel extensions are not installed then the SystemExtension/DNSProxyNE work as expected.


Conversely there are no problems with the third-party kernel extensions if the SystemExtension is not activated/enabled.


It is the combination of the third-party software and the SystemExtension which triggers the problem.


Is this a known issue ?

It’s hard to say without seeing a lot more details. My advice is that you file a bug report about this, so that macOS engineering can take a proper look.

Please post your bug number, just for the record.
