We have a Magic Keyboard which contains a Broadcom BCM20733 BlueTooth chipset.
We need someone to code a simple driver which will allow us do the following:
1. Disable the chipset. At the moment, the chipset is automatically switched on when the keyboard is switched on. Like with a router and wi-fi, we need to be able to turn the Bluetooth off and have it stay off until we enable it again; and
2. Run the Magic Keyboard on both macOS 10.12.6 and Mac OS 10.8.5.
