FAQs
My Bluetooth is greyed out and I can't turn it on. What should I do?
Try restarting your Mac. If that doesn't work, check System Preferences > Bluetooth and ensure that Bluetooth is not accidentally disabled. If it's still greyed out, try resetting the System Management Controller (SMC) – instructions can be found on Apple's support website. A software update might also resolve the issue.
I can see my Bluetooth device but my Mac won't connect. What's wrong?
First, ensure your Bluetooth device is discoverable. Then, try forgetting the device from your Mac's Bluetooth settings and pairing it again. Check for any software updates for your Bluetooth device. If the problem persists, try restarting both your Mac and the Bluetooth device.
My Bluetooth keeps disconnecting. How can I fix this?
Interference from other devices (like Wi-Fi routers) can cause intermittent connections. Try moving your Bluetooth device closer to your Mac or changing the position of your Wi-Fi router. Check for any conflicting software or outdated drivers. If the problem continues, try resetting the Bluetooth module within your Mac's System Preferences (this might require a restart afterwards).
