I update my Macbook Pro* today to macOS Mojave 10.14 (18A391).

I have a Magic Mouse that I've been using for years and that has so far always worked.

However, now the right click with that Magic Mouse does no longer work. I can do a right click with two fingers on my Trackpad but not using the mouse.

I checked the settings and Secondary click is enabled.

secondary click ![secondary

Double-tap to zoom does work fine.

* MacBook Pro with Touch Bar (13-inch, 2017, Four Thunderbolt 3 Ports)

  • sound like MM problem. Do they offer updates ?

  • @Buscar웃: The right click worked just a day ago when I still had High Sierra. So I don't think it's the MM problem. Unfortunately I can't test it right now with another mac.

  • sounds like the communication protocol between MM and mac Bluetooth is broken

  • I have been having this problem too, and I've been doing the command-alt-p-r thing and that works for a few days too. Also only since 14.1.1, on 2012 Retina MacBook Pro.

Reset to default

I resolved it by deleting:

  • com.apple.AppleMultitouchMouse.plist, and

  • com.apple.driver.AppleBluetoothMultitouch.mouse.plist

files from user ~/Library/Preferences/ directory.

  • This worked for me, too. However, I needed to enable the secondary click in System Preferences after removing both files and restarting my Mac.

  • This worked. First delete the .plist, then connect the mouse with a cable so it create a new profile. Also I turned off then on the bluethooth

  • I'm having the same issue, and deleting the above files and rebooting didn't change anything. Also tried resetting the Bluetooth module and factory resetting all connected Bluetooth devices. Interestingly, I only noticed the issue after updating to Mojave 10.14.1. When I was on 10.14 the magic mouse was working fine.

  • Very useful - thank you! This fixed my magic mouse that had been working happily until I installed Mojave. The upgrade to 10.14.1 didn't make a difference.

  • Tried everything without success, seems i need to reinstall macOS (press Option+Command+R while restarting).

Lets try to fix the BT

Hold Shift + Option and click on BT in the menu bar.

Then select Debug.

does anyone reads this

Then do the obvious.

    I did not know the Shift + Option trick. Good to know. I did reset the device and had to re-pair the device but the right click still does not work as you may see in my updated question.

  • It would be better if you didn't leave the last step up to the imagination. I selected the "factory reset..." option, then re-paired the devices in the Bluetooth interface. That solved the scrolling issue. If that is your suggested approach, please include it. If not, please provide your explicit alternative.

Yeah, I did this too. Still doesn't work. What is weird is that I connected the magic mouse to my old iMac running Lion and the right click works just fine. I did all the troubleshooting steps but to no avail. I went and bought a new Magic Mouse 2, and the right click works just fine. Kinda sucks that I had to buy a new mouse, but now I have a nice mouse for the old iMac!

  • Thanks for letting me know. I guess there has to be some other way. I could imagine that this will be fixed in a Mojave update at some point.

I've had to repeatedly remove the mouse from the Bluetooth connections list and repair, which works a while (day or so) before it goes 'missing' again. Haven't found a solution yet that fixes the issue!

  • Hello, thanks for your inputs. Since you haven't discovered a specific solution to this problem I would suggest adding your inputs as a comment rather than an answer.
