I know this question has been beaten dry all over the place because it seems this has been an issue with many and I’ve tried the following during searching for answers:
-Re-installing Unity/MonoDevelop several times
-Deleting all root files except the Temp, LIbrary, ProjectSettings, Assets folder (however problem this seems to be across all projects)
-Re-installing after the deletion of said files
-Sync’d MonoDevelop from Unity Editor
-Changed External Script Editor to point to MonoDevelop App instead of the default MonoDevelop App (built in)
-Deleted preference files from the Library folder relevant to Unity (plist, etc)
-Even tried moving the MonoDevelop app on a different level of the file structure but this seemed unnecessary due to it already being on the same level at the Unity app.
Basically… If you can google if, I’ve probably done it several times and did the steps above several times each in different orders, and I’m ripping my hair out doing so as my time would be better spent working on projects and not on this hinderance.
If anyone can help and offer a solution, I would greatly appreciate it.
