Is the master OD server the same version of OSX as your replica server? If it isn't, you will have an error saying it is imcompatible with your version of MacOS.
Since your getting the 'Error: Unable to determine the master's software version.' that may also be the case but with another incompatible version of MacOS or the Server software in general.
Double check what your Master and soon to be Replicas versions are.
