We recently received our first MacBook Pro with an M1 ARM based processor and the external NIC appears to be blocked by the "ElasticEndpoint" that is running in the Network window. Our other MacBook Pros which are all Intel chip based currently use a USB-C to Ethernet port to hard wire to the netwo…

[Screen Shot 2021-12-02 at 13.45.10] This happens to be my Mac in question. I have used two different USB NIC devices with the exact same result. DHCP or static assignment both fail. The USB NICs are totally INOP with the Elastic Agent installed. Remove the agent and both devices function normally. …

That's interesting. Our network extension doesn't have specific logic to handle M1 processor. Network traffics from either processors are handled with the same logic. Also our network extension doesn't block any network traffic on loading stage. Instead, per our testing result shows, macOS drops all…

No. Please supply make and models of ones you tested with successfully.
