Third-Party Software Notices

MFCommander is proprietary software. It links the following third-party libraries, each used under the GNU Lesser General Public License, version 2.1 (LGPL-2.1). The full license text ships beside these notices in the application bundle and is published at mfsoft.dev/licenses/LGPL-2.1.txt.

These libraries are dynamically linked and shipped as separate .dylib files inside the application bundle (MFCommander.app/Contents/Frameworks/). As permitted and required by the LGPL, you may replace them with your own compatible builds — see Replacing a bundled library below.

MFCommander's own source that calls these libraries only uses their public API and is not a derivative work of them; it remains proprietary.

Components

libsmb2 (SMB2/3 client) — via AMSMB2

• Used for: the in-app SMB connection (SMBClientProvider).
• License: LGPL-2.1 (the library and include directories; see libsmb2-COPYING.txt).
• Copyright: © Ronnie Sahlberg and contributors.
• Source: https://github.com/sahlberg/libsmb2 (shipped unmodified, vendored by AMSMB2).
• Swift wrapper: AMSMB2 by Amir Abbas Mousavian, also under LGPL-2.1 — https://github.com/amosavian/AMSMB2.
• Shipped as: Contents/Frameworks/libAMSMB2.dylib (libsmb2 is statically compiled into this dynamic library together with the AMSMB2 wrapper).

libnfs (NFS client)

• Used for: the in-app NFS connection (NFSClientProvider).
• License: LGPL-2.1 (the lib and include directories; the .x protocol definitions and generated files are simplified BSD — see libnfs-COPYING.txt).
• Copyright: © Ronnie Sahlberg and contributors.
• Source: https://github.com/sahlberg/libnfs (shipped unmodified).
• Shipped as: Contents/Frameworks/libnfs.16.dylib.

Source availability

Both libraries are shipped unmodified from the upstream projects linked above; the upstream repositories are our source offer. If a future MFCommander build patches either library, the patched fork's source will be published under the LGPL and linked here.

Replacing a bundled library

The application bundle is signed with the com.apple.security.cs.disable-library-validation entitlement, so a .dylib you build yourself will load even though it is not signed by our Developer ID. To substitute your own build of libsmb2/AMSMB2 or libnfs:

1. Build a replacement .dylib from the upstream source (keep the same install name / SONAME — @rpath/libAMSMB2.dylib or @rpath/libnfs.16.dylib).
2. Replace the file in MFCommander.app/Contents/Frameworks/.
3. Re-sign the bundle for local use if Gatekeeper requires it: codesign --force --deep --sign - MFCommander.app.
