Ok, well I did a verify disk and once I did that the dock came back. I thought all was goood until the verify finished. The dock went away again. WTF? This is pissing me off.
Did you try Apple-Alt-D ?
I had the same problem, and this fixed it. Thank you!
It's unclear whether that refers just to post #3 or to #2 as well.none of the above worked.
It would be somewhat humorous, but not surprising, if this is the solution.You can also turn it on and off in the Dock section of System Preferences.
