Right click does not work after upgrade to Mojave

After installation Mojave what apps / softwares are used in your Mac post results of etrecheck https://etrecheck.com/

Was it clean installation ( erasing the hard drive and reinstallation ) or an archive installation .

I'm having the same problem with a 2014 Retina iMac 27. If I create a new user and configure right click on that account, it works there. But returning to the original account renders right click broken again.

Thanks, dialabrain. Before I saw your reply I had just tried doing this, rebooting, and then reconfiguring the mouse:

rm ~/Library/Preferences/*[mM]ouse*

That erases every preference with "mouse" in the name, and that fixed it for me. I suspect the single suggestion from your first reply in that thread would have solved it.

The rm option in terminal also worked for me after a reboot whereas some of the other options didn't.

I did forget to reset my preferences in Mouse setup though which took me a few seconds to realise. Now I'm caffeinated, I won't make that mistake again 😉

you are using Mac with Touch Bar , in trackpad gestures check the settings for right click .See this macOS Sierra: Change the way your trackpad works

See if one of these solutions work… Magic Mouse Secondary Click Not Working on macOS Mojave 10.14

Try restarting in Safe Mode. Test. Then restart normally and see if it works.

I've got the same problem as well. Stopped working with my mouse at home, but works with the one in the office 😕

I suspect so. At least you have it working.

For some reason deleted the files in Finder didn't work for me after a reboot. I did the rm above in terminal and it worked perfect after a reboot. Thanks!
