I'm using py2app and package maker to install a python program. The issue I'm having is that if I install as one user selecting 'install for all users' and then switch to a different user the icon for the app is missing- I just get a blank hole, but everything else works fine. I wondered if it was a permissions issue but the only icns file I can find in the package in Contents/Resources is 775. Is this the one that is used by the app?
It's hard to give a lot of information on this but hopefully someone has come across this before or has a suggestion as to why the icon might be missing
Was due to a corrupted plist file. After removing ~/Library/Preferences/com.apple.dock.plist and logging in again it worked
