Any fixes for Dock not following the mouse to move to different monitors in Mavericks?
Are you using a trackpad by any chance? I too thought the way the Dock popped up on different monitors was completely arbitrary or broken, until I found out how it actually works:


If you move the cursor to the bottom edge of either screen and keep your finger on the trackpad, the dock will pop up right away
If you flick the cursor to the bottom edge of either screen (removing your finger from the trackpad as you finish the movement), the dock will not pop up


This is designed like this intentionally so that as you're mousing around in full-screen apps, you don't inadvertently trigger the dock when you use controls at the bottom of the full-screen window.

It actually works really well, once you know how it works ;-)
