It's January 4th, 2026 and this exact problem persists in Mac OS Tahoe 26.2. These workarounds are shit. Don't sell games in Steam claiming they're supported on a Mac if the UI is broken. It makes the game nearly unplayable.
I had the same issue, you can disable pointer acceleration before playing the game and it "fixes" the problem.

I agree with you, it should be fixed by the game and should not require us to change our settings to play it. That said, it is a work around
