Enable/Disable Horizontal Scrolling with Magic Mouse
When I bought my iMac M3 - Sonoma 14.5, I found myself wanting to disable the horizontal scroll feature when moving between fullscreen apps. I looked on forums and found outdated solutions that didn't help me. I wanted to share these steps to help others.
Settings >> Bluetooth >> Click (i) next to Magic Mouse >> Mouse Settings >> More Gestures (tab) >> Swipe between full-screen applications (toggle)
As a bonus, I also found that scrolling up/down was reversed. To change the directionality, simply switch to the 'Point & Click' tab, and toggle the 'Natural Scrolling' option.
Hope this helps!
iMac 24″, macOS 14.5
