It appears that this is a change made sometime last year, applicable to all Apple newer MacBooks.
Implications of permanently fixed MAC addresses on privacy and security are hard to underestimate. Given that Windows now supports complete Wifi MAC address randomization — I am sad to admit that Microsoft looks like a champion of privacy here. What are your thoughts? Solutions anyone knows of (I’ll take a reasonable technical hack). Here are a few mentions of this elsewhere: Mac Rumors forums The GitHub repo for SpoofMAC A discussion on Stack Overflow
I’ve seen other theories about what’s going on, though the bigger question is still what’s the solution? Leave your own thoughts and suggestions in the comments.
And did MacOS stop allowing changes to wifi MAC addresses?
