How to Fix Bluetooth Not Available Error in 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.

TL;DR fix

Start with Fix 1: Reset the Bluetooth Module (Terminal Force). If the issue persists after that, try Fix 2: Remove Bluetooth Property Lists. Full Terminal commands and step-by-step instructions are in each section below.

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.

Recommended Troubleshooting Tool

Before proceeding with manual fixes, we recommend using OnyX. The preferred tool for deep system maintenance and resetting the macOS Bluetooth stack.

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.

  1. Open Terminal.
  2. Run:
sudo pkill bluetoothd
  1. 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.

  1. Open Terminal.
  2. Execute the following:
sudo rm /Library/Preferences/com.apple.Bluetooth.plist
  1. 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:

  1. Shut down your Mac.
  2. Turn it on and immediately hold Option + Command + P + R for 20 seconds.

If the error persists after these steps, try unplugging all USB-C hubs, as some poorly shielded cables can interfere with the Bluetooth chip.
