There is a "local bit" in MAC addresses per RFC 7042, so MAC addresses that have their second character as E, A, 2 or 6 are "local" which effectively means "randomly selected by software". So my current macOS selected MAC address of 16:6a:d2:20:e6:eb is "local" due to the second digit in the address being 6
Oof, I wonder if this is the reason why I constantly have issues with my M1 Mac connecting to cafe hotspots. Regularly I find places that let me connect and then kick me off less than a minute later.
