Cannot Rotate Camera or Edit Sim Body Parts in CAS w/ mouse After Update

Platform: Mac 26.3.1 (a) (25D771280a)

Mods or Custom Content: None. I have never used mods or custom content.

Game Version: 1.123.85.1220

Description:

Since 5/6/26, my mouse controls in The Sims 4 have stopped functioning correctly on Mac.

I can no longer drag or edit body parts in Create-a-Sim (CAS). I also cannot click and drag to rotate or tilt the camera normally. The mouse wheel only zooms in and out, and right-click only allows edge scrolling. Basic clicking and selecting still works, but most mouse movement controls no longer function.

Before this started, the mouse worked perfectly fine.

I primarily play using a mouse, and this issue is severely disrupting gameplay because there do not appear to be equivalent keyboard controls on Mac for editing Sims in CAS.

The only keyboard controls I’ve found that still work are CMD + Up/Down to tilt and < or > to rotate.

I have already repaired the game 4 separate times, bought and tested a completely new mouse, and confirmed that I have no mods or CC installed.

Nothing has fixed the issue.

I searched older threads and found many players reporting similar problems over the years, but I have not found an actual solution or official fix.

I also have a video showing the problem, although I do not think I can upload it here.

Has anyone found a real fix for this on Mac?
