MAC addresses were supposed to be a manufacturer ID + a local ID, so I’m not surprised.

Aren't they supposed also to be tools for the _owner_ (ie purchaser) rather than for companies to retain control of.

If you value personal property and freedom you probably don't buy Apple products to start with.

Your "burned in" MAC address doesn't have to be the MAC it tells other systems in ARP replies, which is pretty much the only way a remote system can find out your MAC (essentially, by asking). It also doesn't have to be the MAC it checks when receiving incoming Ethernet frames.

Most uses of MAC spoofing are for privacy; so that entities that collect every MAC they see over a wireless connection aren't able to track your location.

The intent was was to prevent collisions, but the use is now as a persistent ID, used for tracking.

If you're randomizing, it's best to use the full range.
