When System Integrity Protection (SIP) is enabled on your machine, place the client library file in either of these directories and specify the path to the client library in the Client Library connection parameter:
/Applications.
/Library.
/usr/local.
Do not place the file in the following directories because these parts of the system are protected by SIP and the driver will not be able to access the library:
/System.
/usr.
/bin.
/sbin.
/var.
Pre-installed macOS applications.
If you want to disable SIP on your system, see Sandboxed applications on macOS.
