I'm having the same problem. Built a piece of code as an external framework which can be optionally installed (in Library/Frameworks).
This worked fine until I've enable hardened runtime in my mac os app (even with the "Disable Library Validation" option set).
Both app and framework have the LC_VERSION_MIN set to 10.9, as suggested in this thread:
Both app and framework are signed by me. The application is not sandboxed.
See my response to your other post.
Oh, while I’m here, I thought I’d post an update on this issue…
I worked with FxFactory in a different context to uncover the root cause of their problem. It turns out that this was a
LC_VERSION_MINissue, although not one they can fix directly because the libraries in question come from Apple’s own FXPlug SDK. The fix will require Apple to ship an update to the FXPlug SDK, that is, something later than the current version of 3.1.1 (r. 44639232).
