@westlos said in PFSense and Mac Addresses.:
What about using apps like Facebook
Why would you care if they are? If your that worried, if a real os and not some tablet or phone.. You could change your mac address.. Maybe whatever OS your running on your phone or tablet allows you do it as well?
In windows its as simple as this. You can view your mac in windows with ipconfig /all

Pretty much any OS, and nic driver should allow you to do this. Be careful with what you set it to.. It needs to be valid, and not a multicast mac, etc.
But again - why would you care if some app can see your mac address?
Again as mentioned this mac is used on the local L2 only, it not use with traffic to the internet for example, only for your PC to talk to devices on your network, ie your router lan side interface, etc.
Its a non identifying number, the 1st show you the maker of the device. 00133B for example is

The last 3 numbers would be just the numbers they put on the specific device when they manufactured it.. There is no way to track that to you.. Other than if got with the maker, and said who did you sell this too, hey store who bought this item with serial# (that is if the store actually tracked purchases based on serial# of some nic sold).. Oh F they paid cash - lets go to the camera's, oh there he is buying it with that hoodie.. ENHANCE VIDEO.. Oh its Bob! ;)
Or if that nic was sold to say DELL, then have to get with DELL - hey where did this computer go that you put nic with mac abc in?
I think maybe you been watching too many h@ck3r movies ;)
