Hi,

I've got an unity installaiton which don't work. Unity is constantly requiring change in permissions and crashes afterwards. HTe problem did not exist before upgrading to 2.6.0. I have now installed unity on a second machine without any problems. Great exept that this machine is an old mac at home and not for work.

How do I make a total removal of unity so i can make a clean install ?

Thanks in advance Thomas

In case anyone else would want to remove their preferences:

OS-X's Unity preferences are located in 

"~/Library/Preferences/"

Windows 7's Unity preferences are located in 

"C:\Users\USERNAME\AppData\Roaming\Unity\Editor\Preferences"

Log files are located in

"C:\Users\USERNAME\AppData\Local\Unity\Editor"

or "C:\Users\USERNAME\AppData\Local\Unity\WebPlayer"

In Windows XP/Vista AND Windows 7, open the Registry Editor by typing "regedit" in the search field in the start menu (The "Run" application can also be used and is opened by holding the windows key and pressing "R"): 

"HKEY_CURRENT_USER\Software\Unity Technologies\Unity Editor"

"HKEY_CURRENT_USER\Software\Unity\UnityEditor"

"HKEY_CURRENT_USER\Software\Unity\WebPlayer"

You could try deleting your Unity preferences.

Head to `~/Library/Preferences/`

and you'll find a file called `com.unity3d.UnityEditor.plist` (or `com.unity3d.UnityEditoriPhone.plist` for Unity iPhone)

Make a backup of that, and try deleting it and starting Unity again. You'll lose your window layouts, and last projects opened etc., but other than that it's harmless (and you have a backup anyway).

If that doesn't work, to uninstall Unity simply delete the folder from your Applications folder and reinstall.

You can make it work in 4 steps.

  1. Uninstall Unity.
  2. Remove Unity preferences as described by Nicolaj Schweitz
  3. Reinstall Unity.

  4. Save new projects in a disk location without spaces in the path name.

    e.g

    c:\myUnity\UnityProject (win)

    /myUnity/UnityProject (mac)

The default file name for new projects (New Unity Project) contains spaces which in some systems cause problems. Change it in one without spaces and it will be all right. Notice that the entire path name should be without spaces too, so Documents and Settings is not a good candidate folder to host the project. Make a new folder called e.g myUnity and store your projects there.

Please let me know if this solution works for you.
