Magic Mouse scrolling works for one user account, not the other

MacBook Pro 2020, running Monterey (12.6.2). If I log in as "user a" I can scroll easily with one finger. If I log in as "user b" the same mouse ignores scrolling. As "user b" I can only scroll by use of the scroll bars (click and drag). Same mouse, same Mac, same OS - user login is the only difference.

Other gestures on the mouse surface do not work as well when logged in as "user b", though they do when logged in as "user a".

I compared the system preferences > mouse for both users and they seem to be identical. But something must be different someplace.

So then I created a new user "test user" and logged in. Scrolling works!

Right now only "user b" cannot scroll using the Magic Mouse surface. I don't want to delete/create "user b" as there are many files, etc. within that user's directory already.

Any ideas where to look to fix "user b's" problem?

Thanks,

Gary

To trouble shoot further you can:

—A SafeBoot Use safe mode on your Mac - Apple Support will sort many anomalies

Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

This test will tell you if third party interference; most extensions etc are not loaded in safe boot mode.

unplug all non-essential peripherals when testing

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

all known to cause issues on the macOS

please note—

verify your software is up to date…

The current stable release of Monterey including bug fixes, security updates is macOS 12.7.4 (March 7, 2024)

Keep your Mac up to date - Apple Support

Thank you, Mr Douglas, but unfortunately after booting into Safe Mode "user b" still could not scroll using the surface of the Magic Mouse. I logged out and started normally, but no change. I'm happy to learn that the problem appears not to be caused by the interference of some competing process, though. I appreciate your time to make the suggestion.

I appear to have solved it myself. As "user b" I went into System Preferences > Accessibility > Pointer Control > Mouse Options. "Scrolling"box was ticked so I unticked it (why not?) then backed out of System Preferences. Tested scrolling (still didn't work - no surprise). Went back into System Preferences > Accessibility > Pointer Control > Mouse Options, and ticked the "Scrolling" box and closed Prefs as before. Scrolling now works.
