There are quite a few folders, which behave absolutely normal using the Finder, but when my App tries to do:
it gets an EPERM error: "Operation not permitted”.
When my App shows an OpenPanel (with this un-opened folder), and the user clicks ok, then the open() works just fine.
Isn't that just the normal behavior of the app sandbox? Sandboxed apps aren't allowed to access arbitrary areas of the filesystem, unless the user has implicitly given permission by navigating to a file/folder in an Open panel, or dropping a document, etc.
