Notice: This was unfortunately never confirmed as working properly.

As of macOS 12.3 (Monterey), the MAC address of an interface cannot be modified while connected to a network. That's why LinkLiar (as of version 3.1.0) will disassociate from any connected network before modifying the MAC address. It will then reconnect to the network it was connected to.

Once it has been confirmed that this works as expected this draft release will be turned into an official release.
