Thanks in advance for any help.
I downloaded a Python app called Manuskript, extracted the tarball and tried to make an App from it. Created the directory structure (Manuskript.app, Contents, MacOS, Resources) and copied the whole application tree inside 'Resources', wrote an Info.plist file, and a shell script inside 'MacOS' to launch the application. Used xattr to clear all the extended attributes from every file, and chmoded 755 the shell script.
The App shows in Finder with the correct icon, but it doesn't launch, either with Ctrl-RightClick-Open or a double LeftClick. If I launch it from Terminal, with 'open -a Manuskript.app', it starts and works correctly.
I'd appreciate any suggestions for further things to try.
