System Settings for mouse not saving

In Sequoia, 15.3.2: I go to System Settings > Desktop & Dock > scroll down to Mission Control, click the "Shortcuts..." button, then select my preferences (e.g. Mission Control - Mouse Shortcut - Mouse Button 3) and then, next time I log out (as user) and log back in to the same user account, the previously selected preferences have defaulted back to the factory setting.

This is very annoying: it's surprising how much muscle memory is involved with things like pressing the middle wheel/button of a mouse to do whatever you've set it to do.

I have a new Mac mini (M4) and only recently set it up. The mouse (which happens to be made by Dell) is connected via USB, via a wired Apple keyboard.

It's not a huge issue -- just odd. I have not noticed how many other System Settings are resetting when I log back in (not yet).

Thanks for any advice,

Nick

Mac mini, macOS 15.3

Many thanks for this suggestion. I tried rebooting in Safe Mode, then rebooting normally, but it did not make any difference. I can replicate the problem as described in the original post.

Is anybody else able to replicate this?

Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following;

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.
