    Nothing if your computer is secure. Everything if it is not secure.

    Secure means NO ACCESS to your computer. For example, if he has your password, your computer is not secure.

    I am not a hardware expert, but your MAC address is the unique identifier for your machine. It is burned into your Ethernet chip and cannot be changed. So, if your boss has tools that allow him to capture MAC addresses as part of a traffic analysis, he can identify your machine and where you are going on the network and on the Internet.

    First:
    a MAC-address is not unique, nor is it hardcoded. It's easy to change, or spoof.
    Second:
    a MAC-address is completely useless for anything related to getting information - it CAN be used to spoof access to networks, if someone have been stupid enough to set it up with MAC-address as validation
    Third:
    your boss has no need for this information to check your network-traffic - as long as the company has a somewhat proper setup, checking network traffic is simple as pie

    We are both right, but @PoPSiCLe is "more right" for all practical purposes. The MAC address is an unique identifier that is burned into a machine's NIC card and cannot be changed. However, it apparently is straightforward to spoof that address within the OS which really defeats the purpose of a MAC address, of course. I did not know that.

    "unique" in the way that no two cards/chips from the same manufacturer should have the same MAC. Given that there is no global database for these, and there is a limit on how many MAC addresses you can create within the set limits, MAC collision is a real thing
