Re: SimCity Mouse not working! (at any time)

 - Thank you for including your system specs; it appears the Mojave update may have made some changes that SimCity doesn't like.

Can you try following the steps I posted here: https://answers.ea.com/t5/SimCity-2013/Cursor-less-accurate-on-macOS-10-14-4/m-p/7784938#M127498 and let us know if it helps with your mouse issue?
