How to debug missing libraries on macOS?

Solution 1:

Try this:

$ otool -L /usr/bin/uptime
/usr/bin/uptime:
    /usr/lib/libresolv.9.dylib (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1225.0.0)

(that's on macOS 10.11.6 but should work on newer versions)
