Jumping mouse on Tahoe MAC OS 26

[willybk3]

Installed OS 26 on 2 machines, 2025 Studio Ultra 3 and 2024 MBP, both machines do same thing, mouse will pulse, jump, then go to uper left hand corner making computer(s) unusable! Tried rebooting, un-installing logitech m3s drivers and using apple magic mouse, same thing! Very poor QC on apple's part.

try this - initially on your MBP:

1. remove/disconnect all devices in the bluetooth settings.
2. open a terminal. Type in the command sudo pkill bluetoothd and press return. Enter your password.
3. restart the MBP.
4. pair the BT peripherals and check.

On your Studio - depending the keyboard model you use - you might need a wired keyboard/mouse for step 3.

Found offending app -> Bartender 5. Quit = worked, loaded = jumping curser!

I don't have Bartender, but I have noticed the same from time to time.
