Vulnerability Discussion

The macOS system must be configured to disable Bluetooth unless an approved device is connected.

[IMPORTANT]
====
Information system security officers (ISSOs) may make the risk-based decision not to disable Bluetooth to maintain necessary functionality, but they are advised to first fully weigh the potential risks posed to their organization.

Check

Verify the macOS system is configured to disable Bluetooth with the following command:

/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.MCXBluetooth')\
.objectForKey('DisableBluetooth').js
EOS

If the result is not "true", this is a finding.

Fix

Configure the macOS system to disable Bluetooth by installing the "com.apple.MCXBluetooth" configuration profile.
