I am using the Apple mouse that came with my computer. I do not change any of the settings, the only thing I changed was how fast my mouse goes and that was when I got my computer two years ago. This issue has only been happening for about a few weeks, so I have not changed anything before that.
I have the basic mods like clothing and hair, I have one to make my sims teeth more white, I have one where the CAS lighting is brighter looking, I have skins and makeup, I have MC Command Center.
And my CC is Maxis Match, not the Alpha kind. And I do not use any type of build CC or mods that adds extra playing content in game.
Also I have taken out all my mods and tried it and it still did not work.
