Magic Mouse Secondary Click Not Working on macOS Mojave 10.14

Ever since upgrading my Mid-2012 MacBook Pro Retina 15" to macOS Mojave 10.14, the secondary click (a.k.a. right click) is no longer working on my Magic Mouse.

I have already:

Shift-Option Click Bluetooth Menu -> Debug -> Reset the Bluetooth module
Shift-Option Click Bluetooth Menu -> Debug -> Factory Reset all connected Apple devices
SMC Rest (per Apple Support's advise)
NVRAM Reset (per Apple Support's advise)
Tested with a 3rd Party USB Mouse -> Right Click works without any issues

But the issue persists with the Magic Mouse...

Anyone else having this issue and did you find a way to resolve the issue?

I saw one person on another site having this issue as well.

I am assuming that it will require an OS update to be pushed out by Apple.

MacBook Pro with Retina display, macOS Mojave (10.14)

So I connected a USB mouse, deleted all 4 files within ~/Library/Preferences/ that included the word Mouse, restarted my computer, and it fixed the issue. Thank you all for your help.

The fix is to delete com.apple.Bluetooth.plist. Before you do this you will need to:

Plug in a USB mouse (unless you have a built in Touchpad)
Go to System Preferences > Bluetooth Turn and off Bluetooth
Go to HD/Library/Preferences
Delete com.apple.Bluetooth.plist
Restart your Mac
Go to System Preferences > Bluetooth and turn on Bluetooth
Delete all listed items
Add back your Bluetooth mouse etc.
Go to System Preferences > Mouse and place a tick in Secondary click

This worked for me.

Try deleting ~/Library/Preferences/com.apple.AppleMultitouchMouse.plist and restart.

See if it works in a different user account.

Do you have access to another Mac you can test the mouse with?

Yes, you're right. I forgot to mention that. You need to go back into System Preferences and set the mouse preferences to your liking. Thank you!

HI I tried all that and still didn't work, my scroll gesture also moved to the far right of the mouse, the second click worked for a bit when i changed it fro the right to the left.

but now it doesn't even work at all.

No scroll, No second click.
