Dear Sir
Any possibility of adding the Device’s MAC address?
Thank you!
in short No. There is no accounting need for this, but more importantly this would be useless for Cloud and Server editions as routers strip the individual devices MAC addresses and replace them by the one of the router. So from your screenshot both users if on same network will not show their devices MAC address but will be showing the identical router MAC address. For desktop versions it would just be meaningless.
