OS Mojave - Mouse right click still not working
I have tried deleting com.apple.AppleMultitouchMouse.plist (and also com.apple.driver.AppleBluetoothMultitouch.mouse.plist after that), then restarting. I have tried to debug. I have disconnected - restarting after each of these. None of these have solved my problem of the right click working when I select Secondary Click
If I select the "click on left side", then it works, but my normal left click action stops working.
I'm on Mac MS Mojave (v 10.14.6). It's a MacBook Pro (Retina, 15-inch, mid-2014) with 2.5 GHz Intel Core i7 processor.
According to everything I could find, the solutions I tried should solve the problem. It is not a faulty mouse - the right click worked on a different Mac running a different OS.
Thank you.
