Interface Builder 3.0 crashes on startup

Question

I just bought a new Mac and am running Mac OS X 10.6.4 and trying to run Interface Builder 3.2.4 and when I do it consistently crashes with the following error message:

Assertion Message: Unimplemented error handling: You don’t have permission to save the file “Library” in the folder “Interface Builder 3.0”.

Does anyone have any thoughts on this? It seems like it would be easy enough to try and modify the permissions of a folder, but I have no clue where to find the folder “Interface Builder 3.0”.

Answer 1

I feel dumb now, but hopefully this will help someone along the way. I found the "Interface Builder 3.0" folder in ~/Library/Application Support. My user account only had "Read" access so I changed the permissions to "Read & Write".
