Toot

Anybody know if the Private Wi-Fi address setting in macOS Sequoia is intended to also anonymize the local hostname? I can’t find any documentation of this, but it seems that with this setting on Fixed or Rotating, it’s giving a generic name. Running:

sysctl -n kern.hostname

…results in the following name when Private Wi-Fi address is anything other than Off:

Mac.lan

Switching it to Off gives me:

Thomas-MacBook-Pro.local

Interestingly, scutil —get LocalHostName gives the correct name rather than Mac.lan, but I’m unsure whether this inconsistency is a bug, and if so which is the intended behavior.
