I have a desktop with two computers. On one side I have a Windows PC, and on the other side is a Macbook running OS X Mavericks that is plugged into a Thunderbolt display.
I use a wireless keyboard and a magic mouse. Today, I've been working on my Windows PC, and though my Macbook is booted up, I've left the screensaver running and I haven't touched any of my Mac devices.
Off and on, all throughout the day, the login window keeps popping up on my screensaver. It appears, time's out, disappears and within 10 seconds it appears again.
I've double-checked and nothing is resting on my keyboard and no cables are touching the magic mouse. I know the mouse isn't being bumped or jostled.
Would anyone happen to know if this is an OS X bug or, possibly, a bug with the mouse, sending in micro-movement data to the Bluetooth listener? If so, is there a fix?
I really like my Thunderbolt display. I'd rather not have screen burn-in from the login window constantly overlaying the screensaver, if I can avoid this.
Also, I am not looking to disable the login prompt from the screensaver. I work in an office and it is general practice to always lock your computer(s) when you step away from your desk. I need the login window to pop-up when I need to log into my Mac.
