UPDATE Oct 28 2011
So, I have updated Unity to the newest minor version and this problem has returned. The CodeCompletionData folder listed below, while correctly referencing all the UnityEngine and UnityEditor classes for intellisense / autocomplete, I am once again missing all the basic "System" files from native C#.
And again, if I delete all my old MonoDevelop-Unity preferences (and indeed, reinstall Unity from scratch) and allow them to autopopulate I lose all my intellisense including the UnityEngine and UnityEditor classes.
I suppose I could yet again grab the latest files from my coleague if he's already successfully updated his Unity install, but that's no way to solve this issue and is not sustainable.
Has anyone encountered any problems with the autocomplete feature of the MonoDevelop install that comes with Unity 3.3 on Mac 10.6.7? For reference, it's a version of MonoDevelop 2.4.2.
The autocomplete / intellisense won't actually show any code hints at all except for local variables/methods and static variables/methods that are in the current Class's definition.
By comparison, the "real" version of MonoDevelop has perfectly working autocomplete, but it's not usable by Unity in any real way, so I'm stuck with the broken Unity version.
How can I solve this problem? Working intellisense is very important to me.
After trying kdubb's solution below, I've found that:
Shutdown MonoDevelop and delete all of the ".pidb" files in every folder of every project in your affected solution(s). Then delete all the ".pidb" files in the CodeCompletionCache (1). This should get things working again.
(1) CodeCompletionCache location: Mac it is at "~/.config/MonoDevelop-Unity/CodeCompletionData", Windows it is at "AppDataMonoDevelop-UnityCodeCompletionData".
