I cannot turn off Bluetooth on my iMac, 27-inch, Late 2013, Version 10.12.1. I click on the Bluetooth icon in the menu bar and then click Turn Bluetooth Off. I then get this error message: You cannot control your computer if you turn Bluetooth off at this time. I have no Bluetooth devices connected. System Report for Bluetooth does not show any connected devices. Using Bluetooth Debug I have Reset the Bluetooth Module, Factory Reset all connected Apple devices, and Removed all devices. I cannot turn off Bluetooth in Safe Mode. I did SMC and PRAM Resets. I reloaded the operating system. Apple Care says next step is taking computer in for repair. Is there anything else I should try before taking the iMac to Apple store?
