Thanks for the suggestions, but neither app can reposition my OS X default Dock...my real goal.
MacPilot correctly reads com.apple.dock.plist and shows that my Dock is supposed to be at the top of my screen
<key>orientation</key>
<string>top</string>but neither relocates it to that position nor offers the option. (I wonder what "Default" is if not bottom?)
(Strange, user unfriendly website...does not tell you a product's cost until you open an account.)
Dockit, on the other hand, can place a Dock where I'd like mine to be but cannot rid me of my default Dock.
The bottom line seems to be that Apple has made it impossible for users to relocate their default Dock to the top of their screen.
Clarification: My Dock is a microscopic thing that, nonetheless, annoys me when it pops up from the bottom of my screen, so I'd like to relocate it to the top, from where it is much less likely to drop down.
My only alternative appears to be
Dock Gone, but it's not worth $15 to me.
Thanks again.
