Urgent assistance Please

Dear I am trying to simulate a system, but I am getting an error : ERROR: Unknown improper style (../force.cpp:600)
I checked the manual and I found out that such improper style can only work with USER-NISC packages. I installed Lammps via HOMEBREW and I checked the USER-MISC packages in my machine, it is installed and enabled, so could you help me out to resolve issue ? Kindly check the error below
