Jumpy erratic cursor
I use miniMaC Monterrey
I have a new wired mouse (logitech). I have a relatively new mouse pad. I have cleaned it twice now.
I have had the system in shutdown twice. This last shutdown, I also unplugged every single plug I could find!
NO change in jumpy cursor! Suggestions?
AND: I click on an email...It backlights in black...but then jumps to the very last line on the screen.. This is beyond irritating. What's up here?
Mac mini, macOS 13.3
