He notes in another article[1] that macOS turns on BT on every update, and apparently the behaviour is "functioning as intended" (Apple's own words). What's not answered is why Apple do this. Possibly as trivial as avoiding bug reports or support issues about BT devices or features not working? Apple already control the stack from hardware to software so it's hardly like they would need a nefarious reason to do this.

- bla3 2y agoTheir "Find My" network relies on many Apple devices having Bluetooth enabled and reporting seen device names to Apple (in some anonymized way), as far as I understand. If that's right, then Apple is interested in people not turning off Bluetooth.
- vulcan01 2y agoMacs without input devices (Mac Mini/Studio, iMac) are stationary devices. The devices that primarily contribute to accurate Find My info must be portable, since fixed locations wouldn't help much.
- ksec 2y agoApart from Mouse and Keyboard, I think copy and pasting between iPhone and Mac also requires Bluetooth? And AirDrop? I can see why Apple want this to be enabled.
- based2 2y agomacOS updates 1. Re-active Wifi 2. Re-active Bluetooth 3. Replace with no backup root network filtering rules file: /etc/pf.conf
- idle_zealot 2y agoThey also replace the pam config file, which disables using TouchID for sudo authentication!
- OptionOfT 2y agoThere is now a `/etc/pam.d/sudo_local` that gets queried and survives updates. There is a template here: `/etc/pam.d/sudo_local.template`, copy that one to `/etc/pam.d/sudo_local` and remove the `#` before `auth sufficient pam_tid.so`.

- rwmj 2y agoOK sorry for misattributing!
- cynicalsecurity 2y agoI wouldn't be surprised if the Bluetooth was left as a major vector of attack for people with provided exploits.
