Fix Magic Mouse & Keyboard Not Connecting to Mac — Quick, Reliable Steps

Symptom: Magic Mouse not connecting, Apple mouse not working, or Magic Keyboard not connecting to your iMac/MacBook via Bluetooth. This guide walks you from fast checks to advanced fixes (including resetting the Bluetooth module) so you can get back to pointing, scrolling, and typing.

Quick diagnosis: what’s actually happening?

Start by identifying the failure mode. Is the mouse undiscoverable in Bluetooth settings, shown but failing to pair, or does it pair then immediately disconnect? Each behavior points to different root causes: power issues, software/Bluetooth stack problems, device conflicts, or hardware faults. A clear symptom reduces wasted steps.

Check physical basics first: battery charge or built-in battery state, whether the device is switched on, and whether the device is listed in System Settings > Bluetooth. A drained battery or a turned-off device is the most common culprit—yes, it’s an obvious one, but you’d be surprised.

Next, determine scope. If another Bluetooth mouse or keyboard connects fine, the Mac’s radio is likely OK. If no Bluetooth devices connect, the problem is on macOS (software, drivers, or the Bluetooth adapter). Testing the Apple device on a second Mac, iPad, or iPhone helps isolate whether the device or the Mac is at fault.

Step-by-step fixes (fast → deep)

Follow these steps in order. They move from quick, low-risk fixes to deeper resets. Most users get fixed by steps 1–4.

1. Power & pairing basics: Turn the Magic Mouse or Keyboard off and on, charge or replace batteries, and ensure the device shows a green LED or charging indicator. On the Mac, turn Bluetooth off and on: System Settings (or System Preferences) → Bluetooth → toggle.
2. Unpair and re-pair: Remove the device from Bluetooth devices (click the X or right-click → Remove), then put the device into pairing mode and add it again via System Settings → Bluetooth. Re-pairing clears simple pairing-state corruption.
3. Restart macOS and device: A restart clears transient Bluetooth daemon issues. After reboot, try pairing again.
4. Safe Mode & SMC/PRAM (Intel Macs): Booting in Safe Mode narrows down third-party interference. For Intel Macs, reset SMC/PRAM/NVRAM if Bluetooth behaves oddly. (Apple silicon Macs use different steps: shutdown and wait, then power back on—macOS handles SMC tasks.)
5. Reset Bluetooth module: If the device still fails, reset the Mac’s Bluetooth module (described below). This flushes driver-level caches and paired-device records and often fixes stubborn connection loops.

When and how to reset the Bluetooth module on macOS

Resetting the Bluetooth module clears the macOS Bluetooth stack and paired-device caches. Use this when re-pairing and restarts don’t fix the issue, when multiple Apple devices conflict, or after major system updates that left Bluetooth unstable. It’s safe but will remove Bluetooth pairings—so be ready to re-pair devices.

How to reset (modern macOS): hold Shift + Option and click the Bluetooth icon in the menu bar. In the hidden menu that appears, select „Reset the Bluetooth module” or „Factory reset all connected Apple devices” (label varies by macOS version). Confirm, restart your Mac, then re-pair devices.

If you don’t see the Bluetooth icon, enable it in System Settings > Control Center > Bluetooth or run this Terminal command to show the icon:

sudo defaults write /Library/Preferences/com.apple.Bluetooth ControllerPowerState -int 1

Then restart the Menu Bar or log out and back in. For Apple silicon Macs, a full shutdown and wait (10–20 seconds) then restart also clears internal Bluetooth states managed by the system.

Advanced troubleshooting and hardware checks

If resets and re-pairing fail, inspect for non-obvious problems. Interference is common: Wi‑Fi routers (2.4 GHz), microwaves, USB 3.0 devices, and poorly shielded cables can disrupt Bluetooth. Move the Mac and the mouse/keyboard away from potential noise sources, or temporarily disable nearby 2.4 GHz devices to test.

Check for driver or macOS-level issues by creating a new macOS user account or booting into Safe Mode. If the mouse pairs under a fresh account or in Safe Mode, the issue is likely a third-party kernel extension, helper app, or background process. Look for utilities that manage Bluetooth or USB devices and disable them.

Hardware faults: inspect the mouse/keyboard lightning/USB-C cable and connectors for damage—these are used for charging and sometimes for a wired reconnection. If the Magic Mouse charges but doesn’t pair on any device, it may need service. Test the device on a different Mac or an iPad; if it fails across multiple hosts, contact Apple Support. If it works elsewhere, the issue is the Mac’s Bluetooth adapter or software.

Preventive tips and best practices

Keep your macOS up to date. Apple often includes Bluetooth stability fixes in macOS point releases. Regular updates reduce the likelihood of obscure pairing bugs. Also maintain up-to-date firmware on Apple accessories—these update automatically when connected and charging to a compatible device.

Avoid pairing too many Bluetooth devices permanently. macOS stores paired devices and, in rare cases, a crowded pairing table can introduce conflicts. If you use many Bluetooth peripherals, remove those you no longer use from System Settings → Bluetooth to keep the list lean.

For workflows relying on low-latency input (gaming, audio work), consider a wired fallback or a dedicated USB receiver mouse to avoid Bluetooth disruptions. Also, when you travel, carrying a small powered USB hub and cables gives a reliable temporary wired connection if Bluetooth gets flaky on unfamiliar networks or noisy environments.

FAQ

Why won’t my Magic Mouse connect to my Mac?

Most often it’s power (dead battery), Bluetooth disabled, or a pairing-state conflict. Try charging or replacing batteries, toggling Bluetooth, removing and re-pairing the device, and restarting your Mac. If that fails, reset the Bluetooth module and re-pair.

How do I reset the Bluetooth module on macOS?

Hold Shift + Option and click the Bluetooth icon in the menu bar, then choose the reset option (label varies by macOS). Confirm, restart the Mac, and re-pair your devices. If you lack the Bluetooth menu icon, enable it in System Settings or use the Terminal to ensure the Bluetooth menu displays.

My Magic Keyboard / Mouse works on another device but not my Mac — what now?

If the device pairs with another host, the issue is your Mac. Remove the device from Bluetooth settings, reboot, reset the Bluetooth module on the Mac, and re-pair. If the Mac still fails, test with a new macOS user or Safe Mode to find software conflicts, and check for macOS updates. Hardware repair is unlikely unless the Mac’s internal Bluetooth adapter fails diagnostics.
