Discussion

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

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