I have VMware Workstation Pro installed on my computer, So my computer has several virtual network cards.Why do I get the MAC address of the virtual NIC when I use the getMAC method?

I think you should first determine whether the MAC address is the address of a virtual NIC after obtaining it, and if so, you should look for the address of another NIC instead
