Ever wonder what the process is that manages Bluetooth on your machine? Well, it’s blued. Now, I’ve had the occasion where I wanted to outright disable blued, so I’ve actually renamed it or removed it from my system image. But what if you want to set any preferences for Bluetooth? Well, those are stored in the com.apple.Bluetooth.*.plist file. The * here is due to the fact that it’s based on your machine, thus a ByHost Preference. The location is /var/root/Library/Preferences/ByHost. So if you take that preference file and copy it to another machine it won’t actually work. The other machine will create another as it has a different machine address. So, to configure it you would essentially need to implement login hooks (older revisions you could replace the machine address with an *, which is why I used that here). For more information on login hooks, check out this site (no reason for me to reinvent the wheel here):
