Fix Guide: Bluetooth "Not Available" Error on macOS Tahoe 26.2
Symptom: The Bluetooth icon in the menu bar has a line through it, or the settings say "Bluetooth: Not Available" despite your hardware being functional.
This "module missing" error is usually a software-level lock on the Bluetooth controller or a failure of the bluetoothd daemon to initialize on boot.

Fix 1: Reset the Bluetooth Module (Terminal Force)
Since the hidden "Debug" menu was removed in recent macOS versions, we must use the command line to reset the hardware controller.
- Open Terminal.
- Run:
sudo pkill bluetoothd
- Wait 10 seconds. The service will restart automatically and attempt to re-init the hardware.
Fix 2: Remove Bluetooth Property Lists
Resetting the configuration files forces macOS to rediscover the Bluetooth chip.
- Open Terminal.
- Execute the following:
sudo rm /Library/Preferences/com.apple.Bluetooth.plist
- Restart your Mac.
Fix 3: Perform a NVRAM/PRAM Reset (Intel Macs only)
For Apple Silicon (M1/M2/M3) Macs, a simple shutdown for 30 seconds performs a hardware reset. For Intel Macs:
- Shut down your Mac.
- Turn it on and immediately hold Option + Command + P + R for 20 seconds.
