In this author’s humble opinion, the best place for the OS X Dock is on the right-side of the screen and pinned to the bottom (instead of floating in the middle).
It’s a pretty simple trick — you can move the Dock around all you want with a single line of code in the Terminal and a reboot of the dock.
To start, if your Dock isn’t already on the right (or left) side of your Desktop, you can easily move it by Control+Clicking on that little dividing line, and choosing your preferred position on the screen.
Then, to pin your dock to the bottom, just type this into the Terminal app:
defaults write com.apple.dock pinning -string end
Or if you’d rather pin the dock to the top or back to the center, simply replace the last word of that line (
end) with either
After typing this, you’ll need to reboot your Dock. Do this by restarting your computer, force quitting the Dock from Activity Montior, or typing this into the terminal:
If fiddling in the Terminal freaks you out, there is the more-than-capable app, Cocktail, that lets you adjust all sorts of settings for your Mac, not just where to pin the Dock.
