The MAC address is a code on each of your networking chips that allows it to talk with local networking equipment. This means its only legitimate use is to be broadcast on your local network (or in the local broadcasts for WiFi).
However, it is also often part of the UUID generated by some software and sent to all sorts of online places.
The good news about this is that there are other components of the UUID that are easier to change that will change that ID.
And you can always software mask your MAC IDs if you’re running Linux. This enables your device to pretend the various MACs are numbers of your choosing.

Also I know OP is talking about their laptop, but you can use XPosed modules on an android phone to mask your MAC address too.
edit: as someone who replied to me pointed out, you can apparently do this by default in a lot of android roms
Android can do this by default, no need to significantly increase attack surface by loading third-party code with elevated privileges. GrapheneOS, probably the most private and secure mobile OS out there even has per-connection randomization, the strongest form of MAC address randomization, built in and enabled by default for all networks.
woah, had no idea. i think i thought this bc im running miui rn and its not exactly… the most private OS.

If you’re getting a new phone anyway just get a Google Pixel and install GrapheneOS on it. It’s way more private and secure than Calyx ever will be. It also has per-connection MAC address randomization built in and it’s enabled by default.
